Under the elevated workshop of the gas plant, more than a dozen cylindrical gas furnaces stand on cast reinforced concrete bases. The gas furnaces are sealed with water jackets, and the gas pipelines have been installed on the iron supports of the elevated workshop. , the gas pipeline is made of cast iron, and the joints are sealed with water glass mixed with porcelain powder - this is currently their best anti-corrosion sealing material. [Read the latest chapter] Lingao's huge demand for porcelain powder has led to the emergence of a new industry in Guangdong and Fujian: the acquisition of broken porcelain pieces. The porcelain that was broken or damaged during the firing process in the kiln factory used to be discarded directly. Now there are businessmen who specially buy it, package it and transport it to Lingao. The industrial sector then uses a ball mill to grind the broken porcelain pieces into fine powder for later use.
The valves and flow instruments are self-produced by Lingao, and the quality is not very guaranteed. Therefore, the entire factory is fully open to maximize ventilation and avoid leaks that may cause casualties.
"What's the problem?" Jiang Ye jumped out of the car and first took a look at the birdcage hanging at the door of the workshop - they didn't have special chemicals that could be added to the gas as a warning smell, so they could only use it wherever there was gas. The simplest test for birds. The bird inside looks very lively and has no special state.
"The outlet temperature of furnace No. 4 has risen too fast," the foreman said in a panic and handed over his work record book. He used to be a kiln burner and had a unique skill. He could tell the temperature in the furnace just by looking at the color of the fire. However, since arriving in Lingao, his skills have been replaced by industrial thermometers. Although his secret skills were no longer valuable, his work experience was still useful, so he was trained as a foreman. he
Jiang Ye glanced at his work record book and looked at the situation inside the furnace through the observation window - in fact, he didn't know much about gas furnaces, but he had learned a lot of techniques in this area unexpectedly.
"It should be running sideways." Jiang Ye said. The so-called biased operation means that the ash layer in the furnace is high on one side and low on the other, and the fire layer is also skewed at the same time. The high side is running hot and hot, and the low side is dark and cold, "testing the quality of the gas."
Part of the gas generated in the furnace was directed to the special test combustion port of the branch pipe. They did not have the equipment to measure the gas content, so they had to use the simplest visual combustion method to roughly test several main components in the gas.
"Reported carbon monoxide levels have dropped and carbon dioxide levels have increased," a student who was doing an internship at the construction site reported loudly.
"Bring the stove rod. Go up to the top of the stove and poke the ashes." Jiang Ye greeted, and someone immediately brought the special stove rod over. "You guys, use the hook to pull the ashes from the ash pan and get out the ashes."
Jiang Ye first broke open the accumulated high gray layer and lowered it. Coupled with the following ash removal, a lot of ash residue was cleaned up. Even through visual inspection, it can be seen that the carbon content in the ash is relatively high, which shows that his judgment of the fault is basically correct. After removing the ashes, he asked the workers to use iron drills to compact the areas where the material layer burned fiercely, and added some materials appropriately to keep the material layer even.
After a while, the temperature and air quality of the air outlet returned to the normal range. The fault has been eliminated. Jiang Ye knew that this was the simplest fault in a gas stove, but it was also the most common. The Chuanchuan Group uses gas stoves on a considerable scale, but the problem of shortage of experienced manpower has never been solved. Even important projects like steel plants don't get enough skilled manpower.
He looked at this group of people. Except for the foreman, no one had experience in operating a gas stove. There was still a long way to go in terms of training. When faced with a problem, the foreman himself was confused.
Jiang Ye first briefly analyzed the cause of the failure, how to deal with it and why it should be dealt with in this way. These are very simple things. As long as there is a master master, a group of skilled workers can be brought out quickly. However, the current "master masters" themselves are not very reliable.
Solving the fault is one thing, and you also have to find out the cause of the fault. Jiang Ye knew from the technical manual of the gas furnace that there were not many factors causing the uneven operation. Apart from coking in the furnace, there was a problem with the charge. Judging from the situation just dealt with, the coking in the furnace has been dealt with in a timely manner.
Jiang Ye pinched a handful of coal particles in a basket - the gasifier has a variety of fuels, and what is used here is the washed coal from the coal washing plant, which is the pulverized coal dust precipitated in the coal washing wastewater. After collection, drying and grinding.
The coal powder feels a bit wet in the hand and contains too much water. Jiang Ye gave the first reason in his heart.
"Look, this coal powder is too wet." Jiang Ye opened his clenched fists, and the coal powder fell down in small clumps. "If there is too much moisture, the charging will be uneven, causing the furnace charge to be uneven. So like this The raw materials must be mixed in time after loading." He glanced at it and asked, "Who is loading today?"
"I-" A worker raised his hand hesitantly.
"Why don't you follow the specifications in the operation manual?" Jiang Ye said sternly, "You are going to get into trouble if you are lazy. You didn't work evenly today, and a malfunction occurred. In a light way, it will affect production. In a serious way, if it is not dealt with in time, it will cause a burn. If you penetrate the furnace body and cause a major accident, you will not regret your own death, and you will also risk the lives of your co-workers."
The unlucky worker was so frightened that he couldn't utter a word - the word "death is not enough" was too lethal. If Lingao hadn't been in a "new society" now, he would have knelt down and begged for mercy.
"His work points will be deducted according to the regulations," Jiang Ye said to the foreman. "Have a team meeting after get off work and help him properly."
In addition to commune members, all naturalized workers and employees also began to implement the work-point system, but this kind of labor remuneration was much more complicated than the labor cents obtained by members participating in dispatched work. The HR veterans have begun to formulate and implement a complex compensation system, including the calculation of fixed wages and bonuses, additional benefits and mandatory work-related injury and labor insurance. This system is based on the calculation system of "work points".
"It was Chang who nodded repeatedly.
The foreman failed to fulfill his supervisory responsibilities and was deducted points. The leadership responsibility system is in the promotion stage: since leaders receive more remuneration and receive more benefits than ordinary workers and employees, they also have to bear more responsibility.
On the way back to the headquarters, Jiang Ye took the time to write down the entire process of handling the fault today in his work notebook. Then he wrote down a memo to send to the fuel management department - coal less than 1 omm. Do not use powder as a raw material for gasification. It is better to continue making briquettes. There is also the issue of moisture content. It is normal for the coal to have a high moisture content. At least it needs to be dried for a few more days.
The overhead gas pipeline extending from the gas workshop extends to the open hearth workshop. Most of the overhead base used to support the pipeline is made of bricks. Among the brick columns are wrought iron columns to increase the strength of the entire base. Watching the workers carrying mud buckets and using trowels to lay bricks one by one, Jiang Ye sighed: If there is enough steel, the steel supports of the welded structure will be good, which is easy to build and strong. When will the current days of "replacing melons and vegetables" with industry come to an end? Steel is the backbone of industry. Without enough steel, Lingao's so-called modern industrial system is like suffering from rickets and cannot exert its full strength.
He thought of the discussion about the iron mixing furnace at the technical seminar of the steel complex in the previous stage. At that time, some veterans of the mechanical industry and the metallurgical industry believed that the mixing furnace was an important process equipment in the open-hearth steelmaking method and should be included in the manufacturing project. The so-called mixing furnace is a device mainly used to regulate and balance the supply and demand of molten iron between the blast furnace and the converter to ensure uninterrupted supply of the molten iron required by the converter. The composition and uniform temperature of the molten iron are stored and mixed in the mixing furnace. Converter steelmaking is very beneficial. With the mixed iron furnace, the molten pig iron in the blast furnace can directly enter the open hearth for steelmaking, eliminating the need to first cast it into iron ingots and then melt it in the iron furnace for steelmaking, which can save a lot of fuel. Take full advantage of continuous production.
But in terms of specific manufacturing, the machine tool now needs to manufacture a mixing furnace with a capacity of 50 tons of molten iron, and it also needs to be able to move and turn over. There were a series of problems in the manufacturing of many key moving parts. In the end, it was decided to use the uneconomical but simple process of smelting pig iron ingots - and then purchase them after the materials are improved in the future.
This problem fully exposed the shortcomings caused by the lack of materials. Jiang Ye thought that if the metallurgical department was not able to ensure the supply of steel with sufficient grades, manufacturing these parts would not be completely impossible. Fortunately, the iron mixing furnace is only an improved auxiliary equipment, not a decisive production equipment.
The new steelmaking workshop of Lingao Steel Company no longer uses the past converter steelmaking method, also known as the Bessemer steelmaking method. Instead, the more efficient Siemens-Martin steelmaking method, the open-hearth method, was adopted. Open hearth furnaces are not only used in the steelmaking industry, but also in the glass industry and other smelting industries. It is a very productive process.
Open-hearth steelmaking is a large-scale steelmaking method that uses open-hearth furnaces with coal gas as fuel and directly heats the combustion flame to melt and refine raw materials such as pig iron, scrap steel, and high-grade iron ore into molten steel. In the old days, it was the main steelmaking method still used until the 1960s. Its production efficiency and steel quality were far higher than the traditional Bessemer converter method. The basic working principle of the open-hearth furnace is heat storage. It does not need to build an additional regenerator - it has a regenerator itself.
In the converter steelmaking method, the heat required for smelting comes from the smelting process itself, that is, the heat generated during the chemical reaction of the charge. The open-hearth method requires heat to be provided from the outside. To put it simply, it uses an efficient, controllable and relatively clean gas fuel - coal gas. . ..
