(Please watch the movie network start!) 🔥 Ad-free HD playback! Please tell each other! This is how the largest Sino-Russian cooperation since the 50s began. In order to allow the new Western upstarts in the Russian government to be accountable to the West, China and Russia have adopted a tacit non-governmental approach, handing over the vast majority of cooperation to non-governmental organizations.

Hundreds of Chinese businessmen have plunged into this vigorous cross-border trade, exchanging China's backlog of light and agricultural products for various heavy industrial products from Russian enterprises, and then reselling these heavy industrial products to domestic enterprises to obtain super-profits. At that time, China had just come out of the economic downturn, and the investment in fixed assets was growing rapidly, and there was a very large demand for raw materials and machinery and equipment.

Other businessmen have gone even further, forming consortia to invest in Russia's natural resources, including oil, gas, coal, iron ore and forests. The 3,000 square kilometers of forest that Lin Zhenhua asked Wu Rongxiang to take people to cut down were bought out by him and dozens of other business owners. After the timber is shipped back to China, it can be processed into furniture, flooring and other building panels, which cater to the needs of Chinese families to renovate and replace furniture after large-scale housewarming. Lin Zhenhua knows that the prosperity of the domestic timber market can last for at least 20 years, and whoever has the forest resources in his hands will have a lot of money in the future.

There are also deals that must be done at the official level, and that is in the area of military equipment. Stimulated by the Gulf War, the Chinese military is desperate to acquire high-tech equipment. In order to extricate itself from its economic predicament and to consider such scruples as "long-distance relations and close attacks," the Russian side has provided China with a large amount of equipment, including destroyers, conventional submarines, high-speed anti-ship missiles, and heavy fighter planes. These orders from China have also rekindled the smoke of many Russian military-industrial complexes that have been without food for many days.

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

In this cooperation, GCA has obtained hundreds of Russian technical experts and hundreds of senior technicians, who are assigned to various projects such as chemical equipment, machine tools, steam turbines, refrigeration equipment, etc. The technical level of each project has been raised to a new level.

Thanks to the participation of experts from Russia, the analysis of Russian data by the Hanhua Institute of Technical Information has also deepened a lot. Originally, Chinese researchers could only understand the Russian research materials because they did not understand the research ideas of the Russian side. After the Russian experts came and explained the causes and consequences, many of the problems that had plagued Chinese researchers for a long time were solved.

There is also a lot of equipment from Russia, which greatly enriches the various production departments of Hanhua Heavy Industries. If these equipment are to be purchased on the market, at least 3.5 billion yuan will be required. And Lin Zhenhua bought them from Russia for less than a tenth of the price. in these devices. There are also a considerable number of An Yan and Xiong Lijun, who exchanged the backlog of household appliances.

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

To understand this problem, we must start with the residual stress of the material.

When steel is forged or cast, a large amount of residual stress is generated inside the material. It's like crumpling a piece of tough paper, it will have a natural relaxation force, and inside the seemingly calm steel casting forging, there are also countless such forces waiting to be released by relaxation, that is, residual stress. The presence of this residual stress. It can adversely affect the properties of the material, such as deforming the machined part, reducing the strength of the component, reducing the fatigue limit, etc.

In order to eliminate the effects of residual stress, many methods have been developed, including heat treatment of the material such as quenching and tempering, or some mechanical treatment. Of all the various methods, the one that works best is natural aging. That is, the forgings or castings are stacked in a natural environment, and even let them withstand the sun and rain, so that the residual stress disappears naturally. In order to eliminate stress to the maximum, some materials are even stacked for more than ten years or decades. …,

In order to produce high-precision machine tools, one of the obstacles encountered by Hanhua's machine tool company is the problem of residual stress relief at the base of the machine tool. The machine tool base is generally a large piece of iron casting, if the residual stress can not be eliminated after casting, in the process of use in the future, the stress is gradually released, which may lead to the deformation of the machine tool base, thereby affecting the accuracy of the whole machine tool. Furthermore. In the process of machining, the machine tool will produce strong vibration, and if the base has strong residual stress, it will also accelerate fatigue under this vibration, and damage such as fracture will occur.

Some large machine tool factories in the world have such a tradition. It is to cast some machine bases in advance, and then stack them in the warehouse to slowly eliminate the residual stress, and after ten or twenty years. Then take these bases out and make the machine. This behavior is a bit like a winery storing wine in a wine cellar. The importance of a historic winery to a winery cannot be overstated. Similarly, a batch of machine tool bases that have been stored for many years is for a machine tool factory. It's also precious.

Lin Zhenhua and Ma Shengfan are both engaged in machinery, so they naturally know that there is such a thing as natural aging. Although Cen Youjun didn't understand it in the past, he became the general manager of the machine tool company and slowly learned this knowledge. For the sustainable development of the machine tool company, Lin Zhenhua ordered a batch of machine tool bases to be cast and stored in a special warehouse, ready to let them sleep for 20 years. But this kind of initiative is only for the future to make arrangements, machine tool companies are about to produce products now, the problem of the base is difficult to solve.

In this world, money can buy almost everything, but you can't buy time. I didn't do enough accumulation in the past, but now I have started to do it, which is quite a bit far from quenching my thirst.

By chance, Lin Zhenhua found 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 stacked for decades and are only ready to be used for reprocessing when new machines are being produced. With the dilapidated factory, these semi-finished products lost the meaning of continuing to preserve, and Lin Zhenhua bought them almost at the price of scrap iron, and then shipped them back to Hanhua Heavy Industries.

"That's all good stuff! Lao Maozi is still more experienced than us in industry. 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, and at a glance, most of them are stocks with a history of more than ten years.

"I guess I learned this from the Germans, right?" Lin Zhenhua guessed, "I read the information that there are many cannon barrels stored in the German Krupp Arsenal, and they have been stored for decades, the purpose is to make the stress completely disappear." ”

Ma Shengfan nodded and said: "This is the right thing to do, there are too few enterprises in our country that can do this." In the past, we Luzhong Machine Tool Factory also engaged in the natural aging method, but generally put the casting and forging for a year or two, which is willing to put it for 20 years in one breath. ”

Wang Haisheng, chief of the technical section, said: "There is no way, the main reason is that in the past, our country was too poor, there was a shortage of materials, and how many things were used quickly." If you get a machine tool base and put it for 20 years, you won't let the old men in the Materials Bureau scold you to death? ”

Lin Zhenhua patted the pile of castings and forgings and said, "Everyone, these things are hard to come by, but they are difficult to buy, so you have to cherish them." These bases can only be used in the production of high-precision machine tools. If it is a general machine tool, it is good to use new castings and manual aging treatment. ”

"Mr. Lin, you don't need to explain what you say, these toys are all baby bumps, who is willing to use them casually." Ma Shengfan said to Lin Zhenhua with a smile.

Wang Haisheng said greedily: "Mr. Lin, it seems that there are really a lot of good things in this Russia, so you can make a few more trips and come back with more Tao." ”

Lin Zhenhua said: "No problem, I have already explained to some of the bad men who are engaged in trade in Russia, and asked them to inquire about various enterprises, no matter what it is, as long as it is valuable, they will find a way to get it back." However, I estimate that what can be obtained from Russia is this, Russia has been a little backward in production in recent years, and it is a generation behind the West in terms of technology, and 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, our Hanhua Machine Tool Company, in recent years, is almost a step a year, and now in the domestic machine tool industry, we are not the first, at least in the top ten." If you want to talk about CNC machine tools, let's say second, no one dares to say that it is first. In the next step, we are to develop and expand greatly, and strive to enter the top ten ranks in the international machine tool industry as soon as possible. ”

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, including two five-axis linkage machine tools. Although the machining accuracy of the five-axis linkage is not satisfactory at present, after all, the problem of whether there is or without has been solved, and 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 Company has also continued to expand, and has achieved the goal of 1 billion yuan of annual output value proposed by Lin Zhenhua a few years ago, and is moving towards 2 billion output value. Lin Zhenhua found a competitive target for Hanhua Machine Tool Company, that is, Japan's Xihu Company.
