"Manager Lin, are you saying that your Hanhua plans to take over the 450,000-ton ethylene project of Jiangbei Petrochemical?" Jiang Wu Yuan immediately figured out the joints in it, and couldn't help but ask in surprise.

Lin Zhenhua said: "It's not an intention, but a contract." The Petroleum Corporation, the State Development Planning Commission, and the Major Equipment Office of the State Council have jointly agreed that Hanhua Heavy Industry will be responsible for the general contracting of Jiangbei Petrochemical's 45-ton ethylene transformation project, and at the same time call on petrochemical equipment enterprises across the country to subcontract relevant equipment. ”

"We're going to make 450,000 tons of ethylene ourselves?" Jiang Wuyuan asked. He Lan noticed that Jiang Wuyuan used the word "self", that is to say, Jiang Wuyuan's psychology, whether it was the North Petroleum Machinery Factory or Hanhua Heavy Industry, belonged to "himself", and this "self" of course referred to his own enterprises.

Lin Zhenhua said: "Director Jiang, we must master this kind of thing by ourselves, otherwise, it will be too uncomfortable to be controlled by others." This time, ALK picked on the child, which gave us a warning, the country has made up its mind to show the spirit of the oil battle of the year 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, how can he be so impulsive.

"We at Hanhua Heavy Industries are still little brothers in terms of petrochemical equipment, so the success or failure of this project depends largely on your big brothers. For example, we are still very inexperienced in the equipment and manufacture of large-scale ethylene spherical tanks of this scale, and we need to ask an experienced authority like Director Jiang to guide us. Lin Zhenhua said very politely.

Jiang Wuyuan picked up the drawings again, looked at them seriously, and a wisp of flipping gradually surfaced on his face.

"Manager Lin, your spirit of daring to be the first in the world is indeed admirable. However, I also told the truth that large-scale ethylene equipment is not a simple thing, and we dare not accept it, not because we are timid, but because there are indeed many technical problems that we cannot solve for a while. Jiang Wuyuan said.

"We know that." Lin Zhenhua said, "I came to Beishi Machinery this time, and I also wanted to ask Director Jiang for advice, see what are the main technical problems, and then discuss how to solve these problems." There is nothing difficult in the world, as long as you are willing to climb. I thought, there's a solution to everything, right? ”

Jiang Wuyuan pointed to the drawings and said: "Let's just talk about this ethylene spherical tank, our country has also engaged in spherical tanks in the past, and there are more than 1,000 large and small." But we still have to rely on imports for this kind of large vinyl spherical tank. Why? The biggest problem is the material, low-temperature steel, we can't figure it out. ”

Spherical tanks are containers used in chemical plants to store various raw materials and finished products, and the shape is a spherical shape, hence the name. The ethylene spherical tank is used to store ethylene in the ethylene cracking unit, and with the increase of the scale of ethylene equipment, the volume of the ethylene spherical tank should also increase accordingly. The drawing that Lin Zhenhua just showed Jiang Wuyuan was a spherical tank with a volume of 1,500 cubic meters, and the diameter of this spherical tank was 14 meters, which was equivalent to a five-story building.

If it's just a huge volume, it doesn't matter, a larger volume of containers has also been manufactured by the Northern Petroleum Machinery Plant. The biggest difficulty in the manufacture of ethylene spherical tanks is that the medium in which they are stored is ethylene at temperatures as low as minus 30 degrees Celsius. In order to avoid the extreme low temperature that may occur under the conditions of replacement, pre-cooling and emptying, the design temperature of the ethylene spherical tank should reach about minus 40 degrees Celsius.

The properties of the material at low temperature are very different from those at room temperature, and the general steel will become very fragile at about minus 40 degrees Celsius, and it will not be able to withstand normal impact 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 smelting, rolling and other technologies. In addition, the welds of a large vinyl spherical tank are hundreds of meters long, and the welding dressings used must also be able to withstand low temperature conditions, which is also very demanding. 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 had been hoping that the factory would provide some funding to support him in developing China's own low-temperature steel plates, but the factory was not enthusiastic about this. Jiang Wuyuan himself also knows in his heart that to engage in low-temperature steel plates, I am afraid that it is not something that can be solved by the strength of a factory, which requires the investment of the state to guarantee. However, the country has to engage in more than one or two technologies, and low-temperature steel plates are not on the agenda for a while. ,

"Manager Lin, to engage in this kind of ethylene spherical tank, you need to have imported steel plates, such as the target LT50-V50G", with a yield strength of more than 600 megapascals. But now foreign countries are imposing sanctions on China, and this type of steel plate has also been added to the list of embargoes. Without the steel plate, this spherical tank simply could not be made. Jiang Wuyuan said.

Lin Zhenhua asked: "So, Director Jiang, have you ever thought about doing steel plates yourself?" ”

Jiang Wuyuan smiled bitterly: "If I can do it myself, of course I want to do it." In fact, we also have two steel mills in China that have tried to produce similar steel plates, and the model is 07MNMCCMMOWDR. I have participated in the identification of this kind of steel plate, but unfortunately, our products, the low temperature impact energy at minus 40 degrees is less than 25J, the average low temperature impact energy of others is below 47J, and the single value is above 35J, and the gap between us and others is still very large. ”

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 to change the trace elements in the formula and the smelting method, as long as the experiment is done, there will always be results. ”

"Where's the money?" Jiang Wuyuan said, "To test the effect of trace elements, I am afraid that thousands of experiments will be required." It costs tens of thousands of dollars to refine a furnace of steel, thousands of times, that is, tens of millions of investments, who can get it? ”

Lin Zhenhua said with a smile: "Director Jiang, we may not have to do thousands of experiments. I have some information here, which is the data of the low-temperature steel plate experiment, 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 materials from a small trolley box beside him and pushed it in front of Jiang Wuyuan.

"This is ......" Jiang Wuyuan was a little enlightened for a while, but when he picked up a document to read, his expression couldn't help but become excited: "My God, this is the experimental record of low-temperature materials!" It's so detailed, and it's ...... So much? ”

"Director Jiang, you see, this is information with a formula."

Xu Minxia also picked up a copy of the information and looked at it, only glanced at it a few times, and shouted in a fuss like Jiang Wuyuan. She majored in cryogenic materials, and she had worked with Jiang Wuyuan for so long, so she could naturally see how valuable the information in her hand was. These materials record failed experiments again and again, but such information is also valuable because it can tell latecomers that the road is not going to work, which can save 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 materials we got from the Soviet Union, and there are about a dozen tons of experimental records on low-temperature materials alone." ”

"A dozen tons!" Jiang Wuyuan's eyes lit up with gold.

Ton! What a unit against the sky, who used tons to calculate experimental data? More than a dozen tons of data, if piled up, almost more than 20 cubic meters, can be stacked in a room with 20 false truths 1 meter thick. If all the experimental data recorded in these data are low-temperature materials, then after these data are analyzed, it is estimated that no more experiments will be required to study the appropriate formula.

"Lin experience, how can your actual information be calculated in tons?"

Lin Zhenhua said with a smile: "No way, there are too many materials, when we ship back, we first load the train, and then load the truck, and we need to consider the weight." As you know, trains can't actually hold much, and a wagon can hold up to 60 tons if it dies. ”

What does it mean to be domineering? It's called domineering. Pulling back information from others, I actually think that the carrying capacity of the train is not enough. He Lan sat next to Lin Zhenhua, holding back his laughter, this brother Xiaohua is really too showy.

"What about you...... How much did you save wagons back? Jiang Wuyuan was completely stunned by Lin Zhenhua, and he asked sneeringly.

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

"It's a big deal, it's a big deal." Jiang Wuyuan's eyes widened, and he muttered, "Manager Lin, I finally believe it now, you are really a person who does great things." How can you get hundreds of millions of dollars to get these materials, right? ”

"Uh...... Hehe, hehe, in fact, it can't reach hundreds of millions, a little less than this number. Lin Zhenhua replied duciously. To get this information, he spent slightly more money than waste paper, and one pound of waste was five cents, a ton, or 100 yuan. However, he was still willing to let Jiang Wuyuan maintain a sense of awe, if he knew that the precious information in front of him was only a few hundred yuan, I was afraid that he would have to take out the money to buy and sell it on the spot.

"Manager Lin, if your information can be lent to us for reference, I think it shouldn't be a problem to make a low-temperature steel plate. With the steel plate, all that remains 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, so they have studied the welding process of equipment that can work at minus 40 degrees. Lin Zhenhua said.

Jiang Wuyuan said: "It's really good! If there is a guarantee of information, we only need to apply for a small amount of experimental funds from the factory, and basically the main technical problems of the ethylene spherical tank can be solved. ”

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

"Of course I agree!" Jiang Wuyuan said, "However, there is still a little procedural problem, I can't make the decision on this matter, and it needs to be decided by the factory." In this way, Manager Lin, let's go to the administrative building to find the factory director now. If the factory director doesn't agree, I won't do it, I will resign, and I will go to your Hanhua Heavy Industry! ”
