Chapter 444 Natural Prescription
This is how the largest Sino-Russian cooperation since the 50s began.In order to allow the upstarts of the New West in the Russian government to have an account before Western countries, China and Russia have adopted a tacit non-governmental approach, leaving most of the cooperation to non-governmental organizations.

Hundreds of Chinese businessmen have invested in this vigorous cross-border trade. They exchanged the backlog of light industrial and agricultural products in China for various heavy industrial products from Russian companies, and then resold these heavy industrial products to domestic companies. Obtain excess profits.At that time, China had just emerged from the economic downturn, the investment in fixed assets was growing rapidly, and there was a very large demand for raw materials and machinery and equipment.

There are also some businessmen who are going further. They form a consortium to invest in various natural resources in Russia, including oil, natural gas, coal, iron ore and forests.The 3000-square-kilometer forest that Lin Zhenhua asked Wu Rongxiang to take people to log was bought out by him and dozens of other business owners.After the wood is transported back to China, it can be processed into furniture, flooring and other building panels, which just caters to the needs of Chinese families for decoration and furniture replacement after large-scale housewarming.Lin Zhenhua knows that the prosperity of the domestic timber market can continue for at least 20 years, and whoever has forest resources in their hands will have a lot of money in the future.

There are also transactions that must be completed at an official level, and that is the transaction of military equipment.Stimulated by the Gulf War, the Chinese military is eager to acquire high-tech equipment.In order to get rid of the economic predicament, Russia has provided China with a large number of equipment including destroyers, conventional submarines, high-speed anti-ship missiles, and heavy fighters, regardless of concerns such as "distance and close attack".These orders from China have also rekindled the smoke of many Russian military enterprises that have been out of food for many days.

Lin Zhenhua is an active advocate of Sino-Russian cooperation, and his Hanhua Heavy Industry has naturally become the private enterprise that has benefited the most from this cooperation.

In this cooperation, Hanhua Heavy Industry has acquired hundreds of Russian technical experts and hundreds of senior technicians. A new level has been reached.

Due to the participation of experts from Russia, the Hanhua Technology Intelligence Research Institute's analysis of Russian data has also deepened a lot.It turns out that Chinese researchers can only have a half-knowledge of these materials because they do not understand the research ideas of Russia.After the Russian experts came, they explained the cause and effect to everyone, and many problems that had troubled Chinese researchers for a long time were easily solved.

There are also a lot of equipment obtained from Russia, which greatly enriches the various production departments of Hanhua Heavy Industry.If these devices are to be purchased in the market, at least 5 billion yuan will be required.Lin Zhenhua bought them from Russia at less than a tenth of the price.Among these devices, a considerable part was bought by An Yan and Xiong Lijun with the backlog of home appliances.

In addition to talents and equipment, Lin Zhenhua also scavenged some very precious things from some large factories in Russia, that is, thousands of tons of forgings and iron castings that have been stored for many years.Don't underestimate these silly, big, black and thick iron pieces, they are priceless in industrial production.

To understand this problem, it is necessary to start with the residual stress of the material.

When steel is forged or cast, a large amount of residual stress will be generated inside the material.This is like crumpling a piece of tough paper into a ball, it will have a natural stretching force, and inside the seemingly calm steel casting and forging, there are also countless such forces waiting to be released by relaxation, that is, residual stress.The existence of such residual stress will adversely affect the performance of the material, such as deforming the processed parts, reducing the strength of the component, reducing the fatigue limit, and so on.

In order to eliminate the influence of residual stress, many methods have been developed, including heat treatment such as quenching and tempering of materials, or some mechanical treatment.Among all the various methods, the best effect is natural aging treatment, that is, to stack forgings or castings in the natural environment, and even let them withstand the sun and rain, so that the residual stress will disappear naturally.In order to maximize stress relief, some materials even have to be stacked for more than ten or decades.

The machine tool company under Hanhua wants to produce high-precision machine tools, but one of the obstacles it encounters is the problem of residual stress relief of machine tool bases.The base of the machine tool is generally a large piece of cast iron. If the residual stress cannot be eliminated after casting, the stress will be gradually released during use in the future, which may cause deformation of the base of the machine tool, thereby affecting the accuracy of the entire machine tool.In addition, during the machining process of the machine tool, strong vibration will be generated. If the base has strong residual stress, fatigue will be accelerated under this vibration, and damage such as fracture will occur.

Some large machine tool factories in the world have such a tradition, which is to cast some machine tool bases in advance, and then stack them in the warehouse to slowly eliminate the residual stress. After ten or 20 years, these bases are taken out to produce machine tools .This behavior is a bit like a winery storing wine in a cellar.The importance of a wine cellar with a long history to a winery is self-evident. Similarly, a batch of machine tool bases that have been stored for many years are also very precious to a machine tool factory.

Lin Zhenhua and Ma Shengfan both work in machinery, so they naturally know about natural aging.Although Cen Youjun didn't understand it in the past, he gradually learned this knowledge when he became the general manager of the machine tool company.For the sustainable development of the machine tool company, Lin Zhenhua ordered a batch of machine tool bases to be cast, stored in a special warehouse, and prepared to let them sleep for 20 years.But this kind of action is only a pre-arrangement for the future. The machine tool company is about to produce products right now, and the problem of the base will be difficult to solve.

In this world, almost everything can be bought with money, but time cannot be bought.I didn’t do enough accumulation in the past, but now I’m just starting to do it, which kind of means that I can’t quench my thirst at a distance.

By chance, Lin Zhenhua discovered a large number of precious machine tool bases and semi-finished shaft parts in some machine tool factories in Russia.These semi-finished products have been piled up for decades, and they are only waiting to be produced for new machine tools before they are taken out for reprocessing.With the dilapidation of the factory, these semi-finished products lost the meaning of continuing to preserve. Lin Zhenhua bought them almost at the price of scrap iron, and then transported them back to Hanhua Heavy Industry for thousands of miles.

"These are all good things! The old man has more experience in industry than us." When these forgings and castings were transported to Luzhong Machine Tool Factory, Ma Shengfan looked around them and praised them repeatedly.On each casting and forging, the production date is marked with red paint. Looking around, most of them are stocks with a history of more than ten years.

"Should I learn this from the Germans?" Lin Zhenhua guessed, "I read from the data that there are many cannon barrels stored in the Krupp Arsenal in Germany. They have been stored for decades, and the purpose is to Let the stress go away completely."

Ma Shengfan nodded and said: "This is the correct approach. There are very few companies in our country that can do this. In the past, our Luzhong Machine Tool Factory also practiced the natural aging method, but generally it just put the castings and forgings on a Two years, how can you give up 20 years in one breath."

Technical section chief Wang Haisheng said: "There is no way. The main reason is that our country was too poor in the past and there was a shortage of materials. We used as many things as we had. If you get a machine tool base and put it on for 20 years, you won't let the gang from the Material Bureau Are the old men scolded to death?"

Lin Zhenhua patted the pile of castings and forgings, and said: "Everyone, these things are hard to come by, but they are hard to buy. You should cherish them. These bases can only be used when producing high-precision machine tools. If it is an ordinary machine tool, Just use new castings and artificial aging."

"Boss Lin, you don't need to explain what you said, these things are all precious lumps, who would be willing to use them casually." Ma Shengfan said to Lin Zhenhua with a laugh.

Wang Haisheng said greedily: "Mr. Lin, it seems that Russia really has a lot of good things, so you can make a few more trips and exchange some more for Taobao."

Lin Zhenhua said: "No problem, I have already told some bad guys who are engaged in trade in Russia, and asked them to go to various companies to inquire, no matter what it is, as long as it is valuable, I will find a way to get it back. However, I reckon , That’s all that can be obtained from Russia. Russia’s production has lagged behind in recent years, and its technology is a generation behind the West. If we want to participate in international competition, we still have to rely on our own things.”

Ma Shengfan patted his chest and said: "Mr. Lin, you don't have to worry about this matter. Our Hanhua Machine Tool Company has almost reached a level in the past few years. Now in the domestic machine tool industry, we are not number one, at least It is also within the top ten. If we want to talk about CNC machine tools, let’s say that it is the second, and no one dares to say that it is the first. The next step is to develop and expand, and strive to enter the top ten in the international machine tool industry as soon as possible line of names."

Ma Shengfan's words are not bragging. In the past few years, Hanhua Machine Tool Co., Ltd. has successfully developed more than a dozen high-end CNC machine tools through cooperation with the 858 Factory of the National Defense Science and Industry System and the Spischer Company of the United States. Also included are two five-axis linkage machines.Although the machining accuracy of the five-axis linkage is not satisfactory at present, the problem of whether or not it has been solved after all, the next step is how to optimize it.

With the advent of a large number of new products, the business scale of Hanhua Machine Tool Co., Ltd. has also continued to expand. It has achieved the annual output value of 10 billion yuan proposed by Lin Zhenhua a few years ago, and is moving towards the output value of 20 billion yuan.Lin Zhenhua found a competitive target for Hanhua Machine Tool Company, that is, Japan's Xihu Company.

　I would like to recommend a book to everyone, Takeshita Rika's "50 Years of Masanori", the content of superficial history is written quite easily. Of course, readers who are obsessed with historical knowledge should not read it. Superficial texts will definitely not stand up to scrutiny of.I don't know the author. I saw it by accident in the historical area, and then I saw the latest updated content in one breath. I think it's pretty good.It's a very good book, and the collection and clicks are not high. It shouldn't be. Everyone should contribute to the collection.Let me say something secretly: I have been reading his books for the past two days, so I forgot to write my own book, sorry.
