Chapter 396 Information in Tons
"Manager Lin, are you saying that Hanhua Heavy Industries intends to take over Jiangbei Petrochemical's 45-ton ethylene project?" Jiang Wuyuan immediately figured out the details, and asked in surprise.

Lin Zhenhua said: "It's not a plan, but a contract has been signed. The National Petroleum Corporation, the State Planning Commission, and the Major Equipment Office of the State Council have jointly agreed with Hanhua Heavy Industry to be responsible for the general contracting of Jiangbei Petrochemical's 45-ton ethylene transformation project. Petrochemical equipment companies across the country subcontract related equipment.”

"Are we going to make 45 tons of ethylene ourselves?" Jiang Wuyuan asked.He Lan noticed that Jiang Wuyuan used the word "self", that is to say, in Jiang Wuyuan's mind, both the Northern Petroleum Machinery Factory and Hanhua Heavy Industry belonged to "self", and this "self" of course refers to domestic enterprises .

Lin Zhenhua said: "Director Jiang, we must master such things as large-scale ethylene, otherwise, it will be too uncomfortable to be controlled by others. This time ALK has given us a warning, and the country has made up its mind , we must show the spirit of the oil battle back then, and engage in another big ethylene battle.”

"Great!" Jiang Wuyuan slapped the table heavily, startling both Xu Minxia and He Lan.In the eyes of the two girls, this technical director, who is already five years old, is already at the level of an uncle, so why is he so impulsive.

"Our Hanhua Heavy Industry is still a little brother in terms of petrochemical equipment, so the success or failure of this project depends to a large extent on you big brothers. For example, the design and manufacture of large vinyl spherical tanks of this scale, we still have He is very inexperienced and needs to be guided by an experienced authority like Director Jiang." Lin Zhenhua said very politely.

Jiang Wuyuan picked up the blueprint again and looked at it vaguely, a ray of sadness gradually floated on his face.

"Manager Lin, your spirit of daring to be the first in the world is really admirable. But, let me tell the truth, large-scale ethylene equipment is not a simple thing. We dare not accept it from several large factories. Because we are timid, but because there are indeed many technical problems that we cannot solve for a while." Jiang Wuyuan said.

"We know this." Lin Zhenhua said, "I came to Beishiji this time, and I also wanted to ask Director Jiang to see what the main technical problems are, and then discuss how to solve them. Nothing is difficult in the world. , as long as you are willing to climb. I think there is a solution to everything, right?"

Jiang Wuyuan pointed to the drawing and said: "Let's just talk about this vinyl spherical tank. Our country has also produced spherical tanks in the past, large and small, with more than 1000. But this kind of large vinyl spherical tank, we still have to rely on imports. .What is the reason? The biggest problem is the material, low-temperature steel, we can’t figure it out.”

The spherical tank is a container used to store various raw materials and finished products in chemical plants. Its shape is a spherical shape, hence the name.The ethylene spherical tank is used to store ethylene in the ethylene cracking unit. As the scale of ethylene equipment increases, the volume of the ethylene spherical tank should also increase accordingly.The blueprint that Lin Zhenhua just showed to Jiang Wuyuan is a spherical tank with a capacity of 1500 cubic meters. The diameter of this spherical tank is 14 meters, which is equivalent to the height of a five-story building. It is a giant.

It doesn't matter if it's just bulky. The Northern Petroleum Machinery Factory has also manufactured larger containers.The biggest difficulty in the manufacture of ethylene spherical tanks is that the storage medium is ethylene whose temperature is as low as minus 30 degrees Celsius.In order to avoid the extreme low temperature that may occur when the spherical tank is replaced, pre-cooled, and emptied, the design temperature of the general ethylene spherical tank should reach about minus 40 degrees Celsius.

The properties of materials under low temperature conditions are quite different from those under normal temperature conditions. Ordinary steel materials will become very fragile at around minus 40 degrees and cannot withstand normal impacts at all.Ethylene spherical tanks are bulky and need to be manufactured with large-format steel plates, which also puts forward very high requirements for technologies such as smelting and rolling.In addition, the welding seam of a large vinyl spherical tank is hundreds of meters long, and the welding dressing used must also be able to withstand low temperature conditions, and the technical requirements in this regard are also very high.

At that time, China could not produce low-temperature steel plates suitable for the manufacture of ethylene spherical tanks, but needed to import them from Japan, Germany, Sweden and other countries.Jiang Wuyuan has always hoped that the factory can provide some funds to support him in developing China's own low-temperature steel plate, but the factory is not active in this regard.Jiang Wuyuan also knew in his heart that the production of low-temperature steel plates might not be solved by the strength of a single factory, and it needed the investment of the state to guarantee it.But there are more than one or two technologies that the country wants to develop, and low-temperature steel plates are not on the agenda for a while.

"Manager Lin, to make this kind of ethylene spherical tank, you need imported steel plates, such as Japan's LT50-V-50G, with a yield strength of more than 600 MPa. But now foreign countries are imposing sanctions on China. This type of steel plate It is also included in the embargoed catalog. Without steel plates, this spherical tank cannot be made at all." Jiang Wuyuan said.

Lin Zhenhua asked: "Then, Director Jiang, have you ever thought about making steel plates yourself?"

Jiang Wuyuan smiled wryly and said: "If I can do it myself, of course I want to do it. In fact, there are two steel factories in our country that have tried to produce a similar steel plate, the model is 07MnNiCrMoVDR. I have participated in the appraisal of this kind of steel plate. It is a pity that our The low-temperature impact energy of the product at minus 40 degrees is less than 25J, while the average low-temperature impact energy of others is above 47J, and the individual value is above 35J. There is still a big gap between us and others.”

Lin Zhenhua said: "It's not terrible to have a gap, just continue to improve. To improve the performance of the steel plate, it is nothing more than changing the trace elements in the formula and the smelting method. As long as the experiment is done in this regard, there will always be results."

"What about money?" Jiang Wuyuan said, "To test the effects of trace elements, I am afraid that thousands of experiments will be required. It costs tens of thousands of yuan to smelt a furnace of steel. Thousands of times, that is tens of millions of investment, who can get it?" out?"

Lin Zhenhua smiled and said: "Director Jiang, we may not need to conduct thousands of experiments. I have some data here, which is about the data of low-temperature steel plate experiments. Are you interested in taking a look?"

Speaking of this, Lin Zhenhua made a gesture to He Lan, and He Lan took out a large stack of documents from a small trolley box beside him, and pushed them in front of Jiang Wuyuan.

"This is..." Jiang Wuyuan was a little dazed for a while, but when he picked up a file to read, he couldn't help but get excited: "Oh my God, this is the experimental record of low temperature materials! It's so detailed, and... so much?"

"Director Jiang, look, this is a document with a recipe." Xu Minxia also picked up a copy of the document and looked at it. After only a few glances, she shouted like Jiang Wuyuan.She majored in cryogenic materials, and had worked with Jiang Wuyuan for so long, so she could naturally see how valuable the materials in her hands were.These materials record failed experiments again and again, but such materials are also valuable, because it can tell the latecomers that the road is not working, which can save the latecomers a lot of money and time.

"Manager Lin, where did you get these materials?" Jiang Wuyuan asked Lin Zhenhua.

Lin Zhenhua said: "These are all the materials we obtained from the Soviet Union. The experimental records of low-temperature materials alone are about a dozen tons."

"More than ten tons!" Jiang Wuyuan's eyes glowed with gold.Ton!What a heaven-defying unit this is. Who uses tons to calculate experimental data?If more than ten tons of materials are piled up, they will be more than 20 cubic meters, which can be piled up to a thickness of 20 meter in a room of 1 square meters.If all the data recorded in these materials are the experimental data of low-temperature materials, then after analyzing these data, it is estimated that no further experiments are needed to develop a suitable formula.

"Manager Lin, why are your experimental data calculated in tons?" Xu Minxia asked stupidly.

Lin Zhenhua smiled and said: "No way, there are too many materials. When we transported back, we first loaded the train, and then loaded the truck. We need to consider the weight issue. You also know that the train can't actually hold much. Even if the wagon is stretched to death, it can hold 60 tons.”

What is domineering?This is domineering.Pulling information back from others, I actually think that the load capacity of the train is not enough.Sitting next to Lin Zhenhua, He Lan couldn't hold back her laughter. Brother Xiaohua is really showing off.

"Then...how many wagons did you bring back?" Jiang Wuyuan was completely taken aback by Lin Zhenhua, he asked dully.

"There must be a hundred and ten wagons." Lin Zhenhua said.

"Great generosity, really great generosity." Jiang Wuyuan widened his eyes and murmured, "Manager Lin, I finally believe that you are really a person who does great things. You will need hundreds of millions of funds to obtain these materials, right?" ?”

"Uh...hehe, hehe, in fact, it can't reach hundreds of millions, maybe a little less than this number." Lin Zhenhua replied with duplicity.To get these materials, he spent a little more than buying waste paper, which costs five cents a catty, or 100 yuan for a ton.However, he was still willing to let Jiang Wuyuan maintain a sense of awe. If he knew that the precious materials in front of him were only a few hundred dollars, he might have to buy and sell them by force on the spot.

"Manager Lin, if you can lend us those materials for reference, I think it shouldn't be a problem to produce low-temperature steel plates. With steel plates, the rest is the welding process..." Jiang Wuyuan said.

"We also have some information about the low-temperature welding process. We know that the Soviet Union is a very cold place, and the temperature in winter can be as low as minus 40 degrees. Therefore, regarding the welding process of equipment that can work at minus 40 degrees , They have studied it quite thoroughly." Lin Zhenhua said.

Jiang Wuyuan said: "It's really great! If we have the data guarantee, we only need to apply for a small amount of experimental funds from the factory, and basically we can solve the main technical problems of the vinyl spherical tank."

"So, Director Jiang agreed to cooperate with us?" Lin Zhenhua asked.

"Of course I agree!" Jiang Wuyuan said, "However, there is still a procedural issue. I can't make the decision on this matter, it needs to be decided by the factory. How about it, Manager Lin, let's go to the administrative building to find the factory manager now. If the factory manager does not agree, I will quit, I will resign and go to Hanhua Heavy Industry!"
