Chapter 297 excavation

Long Xiaoyue seldom has any substantive contact with Dongchen's auto business. First, she is not interested in cars and knows little about them. Second, she is busy with all kinds of things in Dongchen pharmaceutical industry every day, and she doesn't have time and mind to worry about Dongchen's auto business. However, she has made limited appearances to let the outside world know that she is the CEO of Dongchen auto , so when a company contacted her and wanted to purchase materials from her, long Xiaoyue was not surprised.

The other side is a trading company located in Zhonghai, whose main business is to purchase various products and raw materials for foreign enterprises in China. This time, the other side contacted long Xiaoyue, claiming to import the raw materials used for the production of transmission system from Dongchen at a high price. The price given by the other side is also very high. 20CrMnTi carburizing steel is commonly used to make gears, The price per ton is about 15000 yuan, but the price of the other party's purchase actually reaches 150000 yuan per ton, which is ten times more expensive than 20CrMnTi carburizing steel, and the first batch of intended purchase volume is more than 100000 tons.

Long Xiaoyue didn't know the strategic significance of this material or Zhang Yunfeng's positioning in this area. She just thought that there might be high profits hidden in this area, so she left all the other party's materials, sent an email to Zhang Yunfeng, and informed Zhang Yunfeng of this situation by phone.

Zhang Yunfeng is very surprised. Zhongchen's new material business has not been really disclosed until now. Besides government and military procurement, Dongchen is the only one in the civil field. The application of aluminum alloy in the engine is very obvious. As soon as someone who is a little knowledgeable opens the engine cover of Dongchen car and looks at the engine manufacturing process, he will know It is inevitable that new materials are used to make the engine block. However, the transmission system is hidden in the car. Moreover, the strength of the steel alloy it uses far exceeds the demand of the civil car. Even if it is an ordinary car, it is difficult for ordinary people to find out the difference of the materials used in the transmission system. Without precise testing, it is impossible to know the potential of this material In strength.

But now, someone even asked long Xiaoyue to buy this material at a price ten times higher than that of ordinary carburizing steel. If they didn't master the specific characteristics and relevant parameters of Dongchen steel alloy, no one would be foolish enough to buy this material at such a high price.

Zhang Yunfeng speculates that this purchase intention is definitely not from the automobile manufacturing industry, because for the industry, the new aluminum alloy used in the engine means a lot more to them than the steel alloy. Then, it's even more strange. In addition to the automobile industry, other people in the industry, who pay so much attention to the situation of Dongchen automobile, and at one breath What's the price? How about purchasing such a large quantity?

Zhang Yunfeng always thought there was something wrong with this, so he opened his mouth and said to Xiaoer, "Xiaoer, please thoroughly check this company called wanshen trade and see who it represents behind it."

Xiaoer also said unambiguously, "don't worry, boss. I will search all the information on the Internet now. Whether it is public or private, as long as its relevant information exists on the Internet, I can find it."

Before long, the waiter opened his mouth to Zhang Yunfeng and said, "boss, I checked all the e-mails sent by the company's official and private affairs, and found that most of the private e-mails were sent to Dong'ou Mitsubishi Heavy Industry. According to the content of the e-mails, the purchase was operated by Mitsubishi Heavy Industry behind the scenes."

Zhang Yunfeng suddenly became alert. If the ordinary people heard the four words, they might think of only Mitsubishi cars and some engineering vehicles. However, Mitsubishi Heavy Industry produced nearly half of Dong'ou's submarines and destroyers, as well as tanks, aircraft and missiles. Even the f 15 fighters of Dong'ou self defense force, more than 200 of them were born by Mitsubishi Produced.

If Mitsubishi wants to buy its own steel alloy, all of this will be explained. Mitsubishi Heavy Industry is bound to have an extreme desire for this material. The significance of this material is mainly in the field of military industry, and its application is very wide. Since Mitsubishi wants to buy it from its own hands, is the price of 150000 too low?

It's impossible for Zhang Yunfeng to directly sell this material to Dong'ou military enterprise. In fact, he has made a statement to the senior management through director Liu. Except for his own use, the flow of this new material is determined by the senior management, who will never sell it to anyone. However, Mitsubishi secretly operated this matter, which made Zhang Yunfeng come up with an idea 。

Any steel alloy has different requirements for forging and smelting methods and addition of alloy elements, such as carburizing steel. Even if the carbon content is 0.01 percentage point different, the material characteristics will change greatly. Moreover, this kind of steel has a unique characteristic, that is, it can't be smelted again, for example, once the steel alloy produced by itself is cooled down After that, the characteristics tend to be stable. At this time, the use can only be carried out in the way of cutting, never melting and then re processing with a new mold. Once re processing is carried out, the characteristics will disappear and become a pile of ordinary steel.

If we seize this feature and dig a big hole for Mitsubishi Heavy Industries to let them jump in, the potential impact will be very huge.

"If I promise to sell them steel alloy, but because of the limitation of export, I can only export it to them in the way of ingot, do you think Mitsubishi will pay?" Zhang asked

Small two clever to smoke, take off the mouth to ask: "eldest brother, you want to pit small East good offices?"

Zhang Yunfeng nodded and said, "yes, I export the ingot to them. If they want to make use of it, they must rebuild the furnace. In that way, what they get is ordinary steel, which is not stronger than ordinary carburized steel."

"No fun." "In this way, xiaodongou will only be fooled by you once. For example, this time, they will buy 100000 tons and transport them back. After the furnace is rebuilt and tested, they will find that if they are fooled, they will not have another time. Moreover, these steel alloys will not be used in actual manufacturing."

Zhang Yunfeng frowned and asked, "what do you mean?"

"I can calculate a new smelting method to shorten the service life of the steel alloy to one year," said the second child with a wry smile

"What do you mean?" Zhang asked, frowning? A year? How is it possible? Even ordinary steel, if properly maintained, has a service life of at least several decades. "

Xiaoer said with a smile, "so we have to design a new way through calculation. In the steel alloy, add some other elements to reduce its tolerance to the change of temperature difference. For example, it can not be heated for a long time. After the heating temperature exceeds the double standards of temperature and time, the strength of the alloy begins to decline."

Zhang Yunfeng asked, "is there a specific plan? More detailed. "

"Any material is very sensitive to temperature, humidity and stress. For example, steel itself is not only affected by heat expansion and contraction, but also eroded by moisture and other substances. Stress will change itself. We can redesign a steel alloy. At first, in terms of parameters, it will not change with our own alloy steel There is a big difference, but once the temperature of a special steel alloy exceeds 60 degrees for a long time, it will start to change its own properties and accumulate to a certain time, for example, half a year or one year. This material will completely lose its original characteristics. If you use it on the tank, the transmission performance of the tank in the first year will be very good, but if the time comes, the transmission performance It will even fade to the point where it can't drive its own weight. Before the engine's output power can be transmitted to the track, the transmission system will collapse, and the gears will all break like porcelain chips. "

Zhang Yunfeng exclaimed, "that's ok?"

"Of course." "I can calculate the use time accurately in hours. Naturally, it will not bring the temperature of the material to more than 60 degrees, but once it is used, the temperature can be easily reached. If the use time is only 500 hours, then after 500 hours, the material will become scrap iron."

"Won't they systematically test this material?" Zhang asked? If they find this characteristic, they will never apply it to military products. "

"It doesn't matter." Xiaoer said with a smile: "in laboratory test, the temperature of transmission parts will not be too high. However, if it is used in practice, there will be a lot of heat generated in the interior of the machine. In addition to the heat conduction effect and the strong airtightness, the temperature will soon rise. Therefore, this material is not worried about laboratory test. Even if it can reach the temperature line in the laboratory, it is difficult for them to connect Five hundred hours of continuous temperature testing. If you think it's not safe, I can set the time to one thousand hours. "

Zhang Yunfeng nodded and said with a smile, "I'd like to give a briefing to Liu Ganshi about this matter. If the senior management approves it, we will do it. If we don't accept it, we can't do it."

Immediately, Zhang Yunfeng arrived in Zhangjiakou. On the one hand, he checked the current progress of the project. On the other hand, he asked director Liu to meet him. The diesel engine production line in Zhangjiakou is now in multiple staffing and 24-hour continuous operation, so it's almost a day. When Zhang Yunfeng last came, thousands of people were busy digging the foundation of the plant. This time, a large area of the plant has already been built Half of the time, many single story plants can be completed only by roof sealing and sealing test.

According to this speed, in another half month, the factory building can be completed, and the production equipment is ready. Once the factory building is completed, it can enter immediately.

Zhang Yunfeng has purchased more than 2000 mechanical arms, and the second child is also building his own more accurate mechanical arms for precision manufacturing, so that after the equipment enters the site, the mechanical arms can be installed and enter the production stage.

After checking the progress of the workshop, Zhang Yunfeng met with Liu in private. As soon as he met, Zhang Yunfeng told the actual situation and said: "two days ago, a domestic trading company found long Xiaoyue and tried to purchase the steel alloy used to make transmission parts from Dongchen automobile. The price they gave was very high, reaching 150000 yuan per ton, and the quantity was very large. The first batch It's 100000 tons, which is more than 10 billion yuan. After the verification of the behind the scenes team, it's determined that the company's behind the scenes is operated by Dong'Er Mitsubishi Heavy Industry in secret. "
