After Yang Peng finished dinner, he called Zhang Xiang and Zhao Jinxi to the study. Let’s discuss the options together. Yang Peng said to Zhang Xiang, "Brother, it will be difficult for us to achieve great development if we continue like this. Moreover, we are facing a behemoth like the Liao Kingdom and there is no future without a reliable base. That is just kidding with the lives of our brothers." , I'm wondering if we should build a city first, develop agriculture and other industries, and then develop the army. The Song Dynasty is not something we can rely on. Their backbone has been broken. In addition, the court emphasized civility over military affairs, and there was discord. It would be good if the Liao Kingdom encircled and suppressed us together, so don’t expect their help. I just want to build a city east of Cangzhou, by the sea, so that I won’t be afraid of the Khitan army encircling and suppressing us. Brother, let’s find a piece of land by the sea of Cangzhou first. Where do you want to take root? What do you think about slowly gathering some refugees first?"
Yang Peng said, "This is the best. We are running around like headless flies now. This will definitely not work. Also, if our goal is to regain the Sixteenth State of Yanyun, we must have cavalry weapons to fight against the Khitan. Only in this way can we hope to regain the Sixteenth Prefecture of Yanyun," Zhao Jinxi said, "Brother, right? We only have so many people now, and even if we are developing, we still have no ability to regain the Sixteenth Prefecture of Yanyun. Even the imperial court has no way, and there is this How much money do we need to spend?" Yang Peng said to Zhang Xiang and Zhao Jinxi, "Our early development was based on refugees. Those landlords who don't have money, the powerful ones have them! As long as the local powerful people and landlords are not good to the people, we are the powerful ones. We have financial resources, so that we can have the support of the people, and the support of the people is the source of financial resources, and the poor people in the Liao Kingdom are also the targets of our struggle. In terms of weapons modification, brother, you have to help us find those who have blacksmiths, carpenters and other craftsmen. We still have nearly 1.5 million taels of silver. Let's stabilize it for a while. Don't launch an attack on the Khitans at this time. When we have a certain strength, we will first rescue the common people in the iron mines. Then we will attack Yingzhou and Mozhou. . We should do it step by step. And we need to inform Yang Tong that they should also pay attention to the Khitan people's strategy. Preserve their strength."
Yang Peng said to Zhang Xiang, "Starting tomorrow, we will go east to Cangzhou to find a place where we can build a city and a place where we can live temporarily. Zhao Jinxi, you stay here, second shift You need someone to take care of you when you come with us," Zhao Jinxi looked at Yang Peng angrily with an unhappy look on his face. There was nothing he could do about Yang Peng's suggestion, so he could only nod and look at Yang Peng with some reluctance. I hope Yang Peng changes his mind.
After Yang Peng, Zhang Xiang, and Zhao Jinxi discussed it, they started observing in the camp for a while. At this time, there were less than a hundred people here. Yang Peng no longer dared to act rashly, because he couldn't afford to lose anything, and he couldn't make a big gain. Function, the most important thing now is the development stage. Without strong strength, it will not work. It depends on how this trip to Cangzhou goes. The most important thing is that you must have the support of the people, so that you can have the reserve force to obtain develop. Only in this way can we be sure to regain the sixteen states of Yanyun. Yang Peng didn't know why he had so much desire for Yanyun Sixteen States. Yang Peng was thinking about who he was, who his parents were, and who else in his family was in this world. Could he be an orphan? Fortunately, you also need to know where your hometown is. Thinking about Yang Peng gives me a headache, eh.
Yang Peng didn't think about it anymore. His head hurt when he thought about it. Zhao Jinxi returned to his room. Zhao Jinxi didn't know why, but Yang Peng was everywhere in front of him, but he felt that he was still not worthy of Yang Peng. I was also thinking that just staying by Yang Peng's side would be enough. Thinking about it, Zhao Jinxi's face was already red. Fortunately, Zhao Jinxi had experienced so much and felt that his heart was turbulent. Zhao Jinxi felt that his spring was coming.
Zhang Xiang is arranging the work of the left-behind personnel, as well as the training of the army, and arranging ten days of dry food because tomorrow Zhang Xiang will go to find a new base with Yang Peng, and it is also for everyone's future thinking, Yang Peng is also here To prepare for the follow-up arrangements, there is no choice but to mess around now, because I can't afford to lose. Since I have everyone with me, I must have a goal, because the Khitan still has nearly 400,000 cavalry, and this is not my little one. You can win the fight just by making a fuss, Yang Peng is also thinking about his brothers in the future.
Early the next morning, Yang Peng took Zhang Xiang, Zhou Dayong and others to Cangzhou with confidence. Yang Peng took the map of Yingzhou. Not to mention that the Khitan map was more useful than the map of the Song Dynasty. It was both strong and accurate. Yang Peng and his party All the way east from Cangzhou, there were basically no ordinary people around at this time, because the Khitan people liked to cut grass. The valley here was already thousands of miles barren and desolate. Yang Peng lamented that this was the result of the war. Yang Peng had walked for two days and had already seen the sea. After walking for five days, he saw a hill less than 200 meters tall. At this time, Yang Peng had made up his mind to go further north. There was also a mountainous area in front of him, which was not big, with only three hills. Arriving at the top of a hill of 500 meters, Yang Peng decided to settle down here, because basically no one would disturb his development here between the Song Dynasty and the Liao Kingdom. The Song Dynasty had no control over this place. It was all wasteland. Feiyao, as long as you grow food here, you will definitely have a bumper harvest.
Now that Yang Peng has decided, he will go back first and then bring everyone here to settle down. After it was settled, Yang Peng also explained the benefits of this place to Zhang Xiang. In addition, after two years of development, there was no local power. The powerful landlords came to earn this piece of land for themselves. Yang Peng and Zhang Xiang said, "You and they will make arrangements when you get back." People are coming over. We are arranging people in Yingzhou to buy grain, cloth, iron, and take in beggars and people in distress. We want no matter who they are. In addition, we are also arranging people in Cangzhou to take in people in distress and buy chickens. , ducks, geese, piglets, etc., just spend money to buy them. I'm here to see how to build a brick kiln first, and I'm also looking to see if there is iron ore here. If not, let's see how we do. In order to get those iron ores, you go back and discuss this with Zhao Jinxi, and that's it. Just leave me with five people here." Zhang Xiang thought about it but there was no other way, so Zhang Xiang returned with the people who took advantage of it. In the secret camp, Yang Peng and Cheng Yu's people began to look for iron ore, stone, and coal mines.
While Yang Peng was thinking about things, other people were already arranging tents and food. The next day, Yang Peng started building earthen kilns with everyone according to his own ideas. The earthen kiln where Yang Peng's team burned bricks seemed very familiar. After five days of hard work, the earth kiln was built, and Yang Peng started making adobe molds again. Yang Peng taught Zhan Jinguo how to do this, and Yang Peng went to the mountains to get some game to improve the food for everyone. Not long after Yang Peng entered the mountains, he He picked up nearly ten hares and a few pheasants. When he returned, he saw that everyone was busy, so Yang Peng cooked for everyone. Everyone saw that Yang Peng cooked the food himself and became more energetic. On the way back, Yang Peng also It was surprising to find that there is a coal mine here. It is not very big but it is enough to develop here for ten years. Wood is now used for iron making. As long as coal is used, steel can be made.
Yang Peng spent ten days exploring all the mountains here. Not to mention the harvest, there are really a lot of game here, including moose deer, goats, and there are still a lot of wild goats here. , Yang Peng was extremely happy at this time. The first batch of bricks was about to start burning. Yang Peng also asked them seriously how to burn the kiln. Nearly fifteen days later, Zhang Xiang and the others came back. This time they brought nearly 500 people, as well as nearly two white carts and nearly a hundred horses. Yang Peng was very happy.
Zhao Jinxi looked very haggard. Yang Peng stepped forward and hugged Zhao Jinxi. Then he and Zhang Xiang hugged each other. They separated after a long time. Then Yang Peng said to everyone, "Hello fellow villagers, I am your head. Here we are." We must start to implement our ideals. There is no oppression here, there is no distinction between high and low, everyone is equal. This is also our beginning, and now we will develop from here. Don't look at the small number of people, a spark can make a difference. Start a prairie fire, as long as we have ideals, we will definitely achieve it. Blacksmiths and other craftsmen should go to Zhang Xiang to sign up, those who know how to farm should go to Miss Zhao to sign up, and those under twelve years old should go to Liu Zhiliang to sign up. , from now on, all children must go to school and learn to read, including girls, and no one can stop them. This is our most important policy. Okay, everyone will arrange to stay here first. Zhang Xiang, please arrange for 20 people to go to the brick kiln factory. Help, from now on we will all have brick houses and there will no longer be those thatched houses.”
Zhao Jinxi led a group of girls to set up camp not far from Yang Peng, and Yin Mingde led 20 people to start training. Yang Peng asked them to buy a large number of items from the surrounding cities this year, including grain seeds and other vegetable seeds. The blacksmith shop also began to make plows. It is the center line, and the left and right sides maintain a balance of equal amounts and unequal shapes; from a color perspective, the color of wood is cold, and iron is also cold, which can achieve visual balance; the plowshare is V-shaped, which is a kind of symmetry, which can give people With a sense of comfort, solemnity, and seriousness, symmetry itself is also a good balance.
Stability is mainly reflected in two aspects: actual stability and visual stability. From a modeling point of view, the plow wall, plow bottom, and press trowel below have a large volume and mass, a downward center of gravity, and are extremely stable. This is actual stability; from a visual balance point of view, the plow frame is made of wood, and the plow frame below is made of wood. The plowshare is made of iron. Since the mass fraction of iron is greater than that of wood, it gives people the feeling that the center of gravity has moved downwards, giving a strong sense of visual stability. In product modeling, change and unity are a very important aesthetic law, which can also be called the general law of formal beauty. The main form of change is contrast, which refers to the degree of difference that highlights certain parts of the shape. Unification mainly refers to the consistency of form and function and the consistency of overall style. In order to obtain the change and unity of product modeling, the main modeling techniques used are: seeking unity in change; seeking change in unity.
In the shape of the curved shaft plow in the Tang Dynasty, although there are straight plow bases, press trowels, foreheads, plow arrows and curved plow shafts and plow tips, their connection methods are the same, and most of them are connected and fixed with arbors, tips and tenons. , and the main body is mainly straight lines. This is seeking unity amidst change.
In the Tang Dynasty, the shape of the curved shaft plow was mainly linear, giving people a strong and stable feeling; but the curves of the shaft and plow tip made the shape richly varied, giving people a dynamic feeling, and acting as a contrast and foil. The curved shaft plow is mainly made of wood, and the iron plowshare and the wooden plow frame form a contrast. This is seeking change in unity. Yang Peng and the others had already stocked a large amount of pig iron at this time, which was enough for them to use for a year. Yang Peng also began to arrange carpenters to make carriages. 1. What are the chassis and steering components of a four-wheel carriage? 2. The carriage of the carriage should not look like a Western style, but should be changed into a Chinese bridge. How to do it. 3. Western-style carriages use belts to pull the carriage. If it stops, won’t the inertia of the carriage collide with the horses? How is it solved in reality? We want to make a small carriage that can be pulled by dogs. In reality, we don’t have four wheels... 4. What are the chassis and steering components of a four-wheel carriage?
Yang Peng finally drew the drawings after two days of hard work in his tent. There are also bearing manufacturing methods. Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving components, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and their prices are also higher. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling elements and cage. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.
Bearings are important basic components of various types of mechanical equipment. Their accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. Among mechanical products, bearings are high-precision products that not only require comprehensive theoretical support from many disciplines such as mathematics and physics, but also require material science and heat treatment technology. Therefore, bearings are another product that represents the country's scientific and technological strength. Needle roller bearings are equipped with thin and long rollers (the roller length is 3 to 10 times the diameter, and the diameter is generally not larger than 5mm). Therefore, the radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter The smallest diameter, especially suitable for support structures with limited radial installation size. Depending on the use occasion, needle roller bearings can be selected as bearings without inner rings or needle roller and cage assemblies. At this time, the journal surface and shell match the bearing. The hole surface directly serves as the inner and outer rolling surfaces of the bearing. In order to ensure that the load capacity and operating performance are the same as those of bearings with rings, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or shell hole should be consistent with the bearing rings. Purpose Combined Rolling The needle bearing is a bearing unit that is composed of a radial needle roller bearing and a thrust bearing component. It has a compact structure, small size, and high rotation accuracy. It can withstand a high radial load and a certain axial load at the same time. Moreover, the product structure is diverse, adaptable and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery, and printing machinery, and can make the mechanical system design very compact and smart.
Aligning ball bearing: A bearing equipped with drum-shaped rollers between the inner ring of two raceways and the outer ring with a spherical raceway. The center of curvature of the outer ring raceway surface is consistent with the center of the bearing, so it has the same alignment function as a self-aligning ball bearing. When the shaft or housing deflects, it can be automatically adjusted without increasing the burden on the bearings. Spherical roller bearings can bear radial loads and axial loads in two directions. Aligning ball bearings have large radial load capacity and are suitable for heavy loads and impact loads. Bearings with a tapered bore in the inner ring can be installed directly. Or use an adapter sleeve or disassembly barrel to install it on the cylindrical shaft. The cage is made of steel plate stamping cage and polyamide molding. Aligning ball bearings are suitable for supporting
Yang Peng also began to build a small blast furnace. Based on Yang Peng's experience, efforts must be made in three aspects: raw material management, furnace operation, and equipment maintenance. Strengthening raw material management is particularly important. The central requirement for improving pig iron quality is to minimize the sulfur content in pig iron. Sulfur comes from coke and ore. To eliminate it, we must first control the raw materials and restrict them from entering the furnace. This is the same as the implementation of the "prevention first" policy in health work. If prevention work is done well, the task of treatment will be greatly reduced; if sulfur is eliminated from raw materials to a minimum, desulfurization in smelting will be easier to handle. In desulfurization before smelting, the contradiction is simple, the operation is simple, and you get twice the result with half the effort; bringing a large amount of sulfur into the furnace for processing will cause a series of changes in the slagging ingredients in the furnace, which is much more complicated than desulfurization before smelting. The successful experience of small blast furnaces in many places shows that the basic requirements for raw material management are "coarse grains and fine grains" and "fine grains and fine grains", so that the blast furnaces can eat fine grains and clinker. By doing this, the improvement of pig iron quality will be the most basic guarantee. But this requires a series of detailed work.
In addition to striving to improve product quality in all aspects of coal mining, coal washing, coking, mining, mineral processing, and sintering, iron smelting plants mainly focus on the five links of roasting, crushing, washing, weighing, and loading. Get rid of the "four hazards" of mud, soil, foam, and impurities (impurities), carry out particle size classification, quality classification, mixing and storage, determine materials by furnace, and strengthen furnace material testing. The measures mentioned above are fundamental measures to improve pig iron quality and increase pig iron production. After layers of checks and measures, most of the sulfur in the raw materials has been removed, and the remaining sulfur must be processed during the smelting process. The successful experience of small blast furnaces in many places shows that improving desulfurization efficiency in smelting, which is the central link in increasing pig iron production, is to implement operating methods of high smelting intensity, high air temperature and large air volume; secondly, it is necessary to strengthen technical management and improve operating procedures , establish a responsibility system and establish a good production order. To ensure that small blast furnaces continue to have high quality and high production, it is necessary to strengthen equipment maintenance, formulate reasonable maintenance procedures, prepare necessary supplies and spare parts, and do everything possible to fight against accidents. If these tasks are done well, the machine can operate normally and the molten iron in the blast furnace can flow continuously.
Yang Peng arranged for fifty people to go to the coal mine to start digging coal, and gave good ideas and methods, and arranged for a hundred people to start building houses. All Yang Peng and the others burned were red bricks, red tiles, red bricks are made of clay, page Sintered building bricks are made from rock, coal gangue, etc., which are crushed, mixed and kneaded, pressed manually or mechanically, dried and fired with an oxidizing flame at a temperature of about 900 degrees Celsius. Also called clay bricks. The technical markings of red bricks are generally No. 75 to No. 100. The size of ordinary fired bricks (red bricks), also called standard bricks, is 240*115*53. (unit mm) Color is bright red, sometimes dark black. Ordinary clay bricks not only have certain strength and durability, but also have certain advantages in thermal insulation and sound insulation because of their porous nature. Therefore, it is suitable for wall materials, and can also be used for building columns, arches, chimneys, floors and foundations, etc. It is often used as a building material in old-fashioned buildings. It is made of clay, waste materials or other local resources as the main raw materials and made with different processes. The bricks used to build load-bearing and non-load-bearing walls in construction are collectively called wall bricks.
The sintered ordinary bricks, which use clay as the main raw material and are batched, prepared, dried and baked, are referred to as clay bricks (symbol is N). There are two types of red bricks and green bricks. When the brick kiln is roasted in an oxidizing atmosphere, red bricks are produced. If the bricks are fired in an oxidizing atmosphere and then stifled in a reducing atmosphere, the red high-priced iron oxide in the bricks is reduced to cyan-gray low-priced iron oxide, and the green bricks are obtained. Green bricks are stronger than red bricks, have good alkali resistance and durability. But the price is more expensive than red brick.
According to different baking methods, sintered clay bricks can be divided into internal combustion bricks and external combustion bricks. Internal combustion bricks are made by mixing combustible industrial waste such as cinder and fly ash into clay raw materials. When the bricks are fired to a certain temperature in the kiln, the fuel in the bricks burns and the porcelain is formed into bricks. Compared with externally fired bricks, internal combustion bricks save a lot of external coal, save 5% to 10% of raw material clay, increase the strength by about 20%, reduce the apparent density of the bricks, and enhance the sound insulation and thermal insulation performance.
When roasting bricks, the heat should be properly controlled to avoid under-fired bricks and over-fired bricks. Underfired bricks have light color, dull knocking sound, low strength, high water absorption rate and poor durability. Overfired bricks have dark color, crisp sound when struck, high strength, low water absorption, but tend to bend and deform. Underfired bricks and overfired bricks are both unqualified products. (1) Basic physical properties: The standard lay size of sintered ordinary bricks is 240*115*53 mm. Adding 10 mm masonry mortar joints, 4 bricks are long or 8 bricks are wide, and 16 bricks are 1 meter thick. 1 cubic meter of masonry requires 512 bricks.
(2) Appearance quality The appearance quality of bricks mainly requires that six items, including the height difference between the two surfaces, bending, protruding height of impurities, chip size, crack length and complete surface, comply with the specifications.
(3) Anti-weathering performance Anti-weathering performance refers to the ability of bricks to resist damage under comprehensive conditions such as wind, rain, freezing and thawing for a long time. Sintered products with small open porosity and small water saturation coefficient have strong weathering resistance.
(4) Flooding and lime bursting Flooding is a salt precipitation phenomenon when bricks are in use. Excessive soluble salts in the brick absorb moisture and dissolve, then migrate to the brick surface as the water evaporates, and crystallize out under supersaturation, causing the brick surface to appear as white attachments or expand, causing the brick surface to peel off from the mortar plaster layer. For high-quality bricks, no frost is allowed, and qualified bricks must not be severely frosted. Lime bursting refers to the phenomenon of lime blocks mixed in the brick body, which absorb moisture and mature to cause expansion and bursting. For high-quality bricks, burst areas with a maximum damage size greater than 2 mm are not allowed; for qualified bricks, burst areas with a damage size greater than 15 mm are not allowed.
What happened after all, let’s see what happens next.
