important!
The value and importance of this technology cannot be described in words. Although the three of them have not yet formally experienced the power of modular construction technology, they have been deeply shocked by their imagination and paper data.
Not only is the construction efficiency more than ten times that of traditional construction methods, but the scope of application is also extremely broad, involving many important fields.
Let’s see what application fields Yu Hua mentioned? Engineering and construction fields, house construction, shipbuilding, aircraft building, and tank building.
"If we use modular construction technology on a large scale from a national perspective, wouldn't our country soon become an industrial power?" Lin Wan, whose thoughts were surging, stared at Yu Hua with burning eyes.
All eyes fell on Yu Hua.
Seeing the expectant looks on the faces of Lin Wan and the others, Yu Hua shook his head gently and had to pour cold water on them: "Yes, and no."
"How?" Zhou Yuan asked curiously.
"The advantages of modular construction technology are very obvious. It can greatly shorten the construction period and improve construction efficiency. It can indeed speed up the industrial development process and shorten the time to become an industrial power. But the premise is that you must first have a set of basic industries covering major categories. Systems and industrial standards are the two key things I mentioned before, standardization and industrialization, which are the soul of modular construction technology."
Yu Hua slowly explained: "The so-called standardization and industrialization are directly reflected in the industrial standard system and basic industrial system. These two things are currently unavailable in our country. Without a complete standard system covering major industrial categories, unified design cannot be achieved. Without a basic industrial system, we cannot produce products that meet the design. In addition, we also need a strong government that is willing to invest money."
The warships of the Chinese Navy in the prosperous times, super bridges, large-scale infrastructure, and high-rise buildings all reveal the presence of modular construction technology.
From an objective perspective, modular construction technology is indeed an artifact in the industrial field. However, in order to use this technology, prerequisites must be met.
Without basic industry and standardization, without a strong government that is willing to invest money, you can just implement modularization with a hammer.
After hearing what Yu Hua said, the three people all woke up. The situation in the country was obvious to all, and it was simply unrealistic to expect the National Government to use modular construction technology on a large scale.
However, organizations can use it.
"Team leader, were you the first to create the concept of this technology?" Fang Yu recorded all the key points about modular technology, put down his pen and raised his hand, and asked.
"Of course not. This technical concept was used in the Crystal Palace of the 1851 World Expo. I just summarized and refined it and stood on the shoulders of giants." Yu Hua smiled.
"The prerequisite for standing on the shoulders of giants is to be able to climb on the shoulders of giants first. Team leader, you are really outstanding." Fang Yu said word by word, giving a heartfelt evaluation.
"Fang Yu is right." Zhou Yuan agreed.
Lin Wan nodded.
Yu Hua smiled: "Thank you, but we are not holding a commendation meeting, but a technical seminar. Let's continue the discussion."
"As for the issue of obtaining processing equipment, Lao Liu has already given me an answer. All the processing equipment and materials you listed can be obtained, but the price is very expensive, especially the submerged arc welding machine. An American named Johnson in Tianjin Wei owns it. There is a semi-automatic submerged arc welding machine, the asking price is 2,000 oceans per unit, and the fusible sintering flux is 500 oceans per ton." Lin Wan nodded, raised her right hand, and then informed the investigation status of the processing machinery and equipment.
By the end of the sentence, my eyelids were twitching.
You really wouldn't know if you didn't check. Once you checked, you would be shocked. The cost of these processing equipment and materials was completely beyond Lin Wan's imagination.
After almost all the efforts of the Northern Department were mobilized to investigate and collect information overnight, we have basically found the 16 types of machinery and equipment and required materials on the equipment and materials list. Fortunately, these equipment and materials can be purchased in Tianjin Wei. The question Yes, it's expensive.
"How many submerged arc welding machines does this American have?" Yu Hua suddenly perked up, his eyes flashed, and he looked at Lin Wan with a hint of urgency in his words.
Seeing Yu Hua's anxious look, Lin Wan was confused and responded: "It is said that there are three units with ten tons of flux. What's wrong?"
"Jinyu, Xiaoyu, Lao Zhou, if you want to put the seven-tower device into large-scale production and construction after it is successfully developed, listen to me and buy all three submerged arc welding machines and fluxes. Don't give up the core just because of money. Equipment, you have to know that some important equipment cannot be bought with money." Upon hearing this, Yu Hua looked slightly serious and made personal suggestions to the three of them.
purchase!
Buy them all!
money?
In front of three submerged arc welding machines, it is nothing. You must know that this is the latest welding technology that was born in the 1930s, and it is a real high-end welding technology.
The most important thing is that the submerged arc welding machine can not only solve the welding problem of the core pressure vessel of the seven-tower device, but is also the front-end technology of electroslag remelting technology.
Among the three advanced metallurgical processes of later generations, electroslag remelting technology has not yet shown its charm to the world. The working principle comes from submerged arc welding, which uses the protective method of slag to isolate air to refine and purify metals.
The world's first electroslag remelting furnace and the world's first submerged arc welding machine were both created in 1930 by Americans. However, submerged arc welding was vigorously promoted, and electroslag remelting was not used at the beginning of its birth. It received great attention and was later carried forward by the Soviet Union and became one of the strategic processing technologies in the military field.
The electroslag steel after electroslag remelting has high purity, dense and uniform internal structure, smooth surface, and excellent various properties. Products such as gun barrels and bearings made of electroslag steel are several times more expensive than ordinary steel. .
With this high-end metallurgical technology, the Eighth Route Army, which has always been short of artillery, will completely solve the problem of lack of artillery and weapons. What tank barrels, what mortar barrels, what howitzer barrels, cannon barrels, gun barrels, these are no longer Dream well.
If the oxygen top-blown converter technology that Yu Hua plans to develop can solve the problem of steel sources for the Eighth Route Army, then the electroslag remelting technology can solve the source of high-end military weapons materials.
As for why Yu Hua knows that the front-end technology of electroslag remelting technology is submerged arc welding, the reason is very simple. There is a high-end knowledge community with an average of 985 per capita - Zhihu.
"Okay, I'll ask Old Liu to buy them all immediately." Lin Wan nodded. Although she could not realize the value of the submerged arc welding machine, Yu Hua's serious attitude and words made her understand the importance and luck of this equipment.
Yu Hua is right. Some important equipment cannot be bought with money, and people simply don't buy it.
By chance, she was lucky enough to come across three submerged arc welding machines.
Fang Yu and Zhou Yuan did not object and nodded in agreement with the suggestion.
"Has the location for the experimental device been chosen?"
"Initially, we are considering setting up a village in Zhaobeikou, Baiyangdian. It has abundant water resources, convenient transportation and is remote. The construction is not easy to be discovered by the outside world. What do you think?"
"Baiyangdian? Okay."
"I think it's not good to call the seven-tower device this way. There are five, six, and seven towers in the chemical industry around the world. It's impossible to make an effective distinction. We should give the project a formal name. Didn't the team leader say that Yu's Seven Pagodas? I think it can be renamed Yu’s Seven Pagodas directly to facilitate management and recording.”
"Fang Yu is right, I agree with calling it Yu's Seven Pagodas."
"Okay, let's call it Yu's Seven Pagodas."
The seven-tower device officially became Yu's Seven Towers. Everyone then continued to discuss technical issues one by one, and quickly summarized and revised them. Yu Hua accepted the good suggestions and rejected the bad suggestions.
