Steel balls are undoubtedly a major metal composite fiber textile raw material consumption part at the present stage of industrial production and even can be expected in the future. According to the information of raw materials, in 2008, only one field of mining plant in our country consumed about two million tons of steel balls of various raw materials. The steel ball is round, there has been a physical change, there are neat or non-periodic garden steel bars, galvanized square steel bars, after raising temperature, at a certain setting temperature, with the aid of abraded tools to create a shape, intelligent professional ability in recent years has created a new turnover, Completed the complete and continuous continuous extrusion machine production and roll forging production and manufacturing of the gratiing step, I am sure that generations of steel ball people will continue to work hard again and again and again and again, because it is a joy, you step into the vast expanse of the steel ball, you will feel that it is not a very astringent steel block, It is also reiki, it is beautiful to become, you imagine: A round steel ball scattered in the cement ball mill, in the continuous operation, the large iron ore to break, willing to dedicate to the whole body, and the diet of Curie everything is closely related to each other, how like everyone's Tiangong 1, 2, in search of, in operation. 1, steel ball growth stage: in China's steel ball production and manufacturing has a long history of development prospects, from the stage of China's Anti-Japanese War to integrate into the maintenance of ordnance in Wafangdian to create a cylindrical roller bearing manufacturing manufacturer in China - that is, the current name of the tile shaft. Because the development trend is relatively late, it is not possible to produce steel balls, at that time, in order to better be able to better be able to better be able to better manipulate the production and manufacturing of cylindrical roller bearings in our country, steel balls have been all manufactured in Japan, and after transportation, they are installed in our country. At the beginning of the release, some workers of Wafangdian bearing factory were unwilling to follow the spirit of the essence, marketing strategy of their own production and manufacture of steel balls, in the absence of professional ability, no engineering drawings, industrial equipment is very outdated conditions, everything is produced by themselves a grain of steel ball in China's ancient history, the development trend in China's steel ball development process. Tracing the development of the whole steel ball, from Spain in 1883 to create the whole steel mill, although the product product design initial, simple structure, but the development trend to see the production of steel ball examples. After the liberation of our country, in order to better be able to better be able to better repair social development as soon as possible, social economic development, social development and social economic development, the basic policy of the overall planning of the industrial chain was created, and a large number of enterprises were created. However, as a gold, agricultural machinery, chemical plants, cars, large tractors, processing center production and processing management office, the key parts of the new material industry can not be lacking - cylindrical roller bearings, but from the technical point of view, in a very outdated situation, cylindrical roller bearings have undoubtedly become the key development prospects of the field at that time. The tile shaft becomes the key development prospect of the company. In order to better integrate into the development future as soon as possible, the former Soviet Union had to introduce the excellent steel ball production and manufacturing professional capabilities and industrial equipment at that time, and sent staff to the former Soviet Union to carry out learning and training, the Luoyang Bearing Factory was created in Xuchang City in the 1950s. It means that in the field of cylindrical roller bearings in China, it has professional skills, the overall planning of the whole industry chain, and intelligent system production and manufacturing. At that time received some standard restrictions, mainly the damage of the former Soviet Union processing process copy, then from the original manufacturing to installation are carried out by a company, steel ball is the key composition of the cylinder roller bearing precast components precast components, in order to fully consider the requirements of various bearing factories, With the assistance of the former Soviet Union, the automated production line and steel ball factory specializing in the production of steel balls were created, and a lot of steel balls were produced at the beginning. The shaft, the shaft and the shaft can be called the origin of the steel ball in our country. At that time, their industrial equipment, processing process spacing is not very large. At present, many companies still continue the production and manufacturing process at that time: the use of cold upsetting - hard grinding method. That carried out the six links of steel ball in our country so far: one link: Before the 1970s in our country, it was not a processing technology, simple and rough; The second stage: 1971-1983: The key is the production of iron slice ball, processing technology is simple and outdated; The third stage: 1983-1992: At the beginning to grasp the key to scientific research, gradually to the professional development of the future, but the pile density of steel balls is high, during this period has not forgotten to grasp the necessity of steel ball arc laser welding arc welding welding stress field; The fourth stage: In 1991-04, the professional ability of processing technology gradually improved, the commodity oriented, alloy steel, bonded steel and even martensitic steel balls at the beginning of scientific research, to the market, with targeted steel ball heat treatment process methods, industrial equipment to make spiral mechanical equipment, the application of salt bath heat treatment process method of professional ability, In addition, the improvement of the technical transformation project began in the first place, and gradually changed from the traditional coal temperature raising method to the whole process of production and manufacturing of - gas producer furnace - gas heat treatment electric furnace - heat treatment electric furnace; The first three links, especially the first and second links, the cement ball mill above 6m is still just a development prospect, and coal mining has long been gradually popular, therefore, after 2001, in fact, the steel ball to the total value and quality of the real link. The fifth link: 2005-2010, promote the overall planning of production and manufacturing for the industrial chain, improve the benefits, in China's steel ball is slowly recognized by all large and small coal mining, facing the government, at the beginning to take the professional road; Session 6: So far in 2010, the development prospects are very fast, to Shandong Province calcined Xanaduyuan Zhangqiu City as an example, from the total value of more than 10,000 tons in 2001, more than ten years of development prospects at this stage ** more than 300 thousand tons, not to mention the professional ability in the continuous upgrade, raw materials in the continuous improvement, coal mining application of cement ball mill in the continuous expansion, The regulations on steel balls are also being developed and innovated. 2, how can the steel ball crush? Whether the production of steel ball manufacturers or in the application of steel ball mining, will encounter such a problem, in the cement ball mill operation in the whole process, the steel ball will be crushed, how to crush it - a fundamental problem is arc laser welding arc welding welding stress field: Simply put, arc laser welding arc welding welding welding stress field is to consider the level of deformation of the object, compressive strength, fracture toughness and other related to the work of the object is ineffective scalar; Easy to understand a little, arc laser welding arc welding welding welding stress field is the internal gas pressure, talk about here first tell a story: In the 1970s, when I first entered the manufacturer, I saw piles of calcined products piled up on the vacant pavement in the manufacturer. The products looked like they had been sitting there for a long time because of weeds growing around them. This kind of calcined product product product product workpiece is not manufactured, put in there to the sun and rain? So I turned to a master of the automated production line for advice. The master told me: It is to better be able to better be able to better be able to better be able to better be able to better clear the arc laser welding of aluminum casting parts arc welding welding welding stress field. Aluminum casting after forging hammer production, like kneading dough, but the batter inside a little more kneading here, there will be a little less kneading, the internal mechanism is not symmetrical, close contact is loose and inconsistent. If the newly calcined product product workpiece is immediately produced by the production and processing management office of the processing center, the production and manufacturing of the live dial indicator and vernier caliper, the precision of the model specification meets the requirements of the actual engineering drawings, but after a short time, the precision of the model specification does not pass the standard. What's the problem? Arc laser welding in aluminum casting parts arc welding welding welding stress field has not been completely solved, in the "resistance", resulting in product product product product product workpiece deformation. The way to deal with it is not to rush production and manufacturing, throw the product product product workpiece aside, and wait for its arc laser welding arc welding welding stress field to be completely solved, the internal organizational structure is symmetrical, loose and closely related to the same, and then go to production and manufacturing, the production of manufactured products product product product product model specifications are not easy to change, From aluminum casting parts or steel balls to remove arc laser welding arc welding welding stress field, we see some things in life, for some "arc laser welding arc welding welding stress field" is very large, don't worry about immediately deal with, and should be "family cold violence", put it, let them "don't be angry", release the industrial equipment mechanical energy, Adjust the connotation, so that you can achieve high-quality expectations. The stress field of arc laser welding is like a person's stomach, for example: some people eat shepherd's purse, it will rise stomach pain, using two methods, one is to quickly eat food tablets, so that it can return to normal; The second is the return to normal after diarrhea; The eating tablet here is to remove the effect of the stress field, diarrhea is in fact arc laser welding arc welding welding stress field to remove, as far as possible diarrhea, for the steel ball is crushed - that is, speaking of arc laser welding arc welding welding stress field, why not broaden it, There are four ways to remove the stress field of electric arc welding: A, heat treatment process Heat transfer medium: choose heat treatment electric furnace, gas furnace, kerosene furnace temperature - temperature reduction; B, gentle heat treatment process method: after calcination of the steel ball, choose the way of heat insulation and cooling; C, collision method: select the ball section to select industrial equipment, barrel collision method; D, naturally ineffective method: naturally, the stress field is cleared (the small story of the lathe worker is naturally ineffective method); 3, from the difference between the steamed bread and the paper said that the steel ball diesel engine diesel engine diesel engine diesel engine compression ratio problem: At present, there is a problem that is good, that is, more than 20 years ago in China's skew professional ability has long been very good, how the steel ball factory has not been fully mobilizing it, is the problem of assets, professional ability, or the problem of work, the response is NO, this is a comprehensive problem, can not only talk about the steel ball, continuous continuous extrusion machine mature, Only industrial equipment conditions, not necessarily other public cultural service projects machinery and equipment industry chain are mature, such as: Park steel stainless steel rod, accompanied by the continuous promotion of professional ability, continuous marketing and promotion of new materials, in recent years, it has a grasp of the problem of the compression ratio of steel ball diesel engine diesel engine diesel engine diesel engine diesel engine diesel engine compression ratio of the past diesel engine diesel engine diesel engine does not attach great importance to ** several times, At present, it has become one of the key professional competence standards of stainless steel plate and stainless steel bar, which is more than ten times or even dozens of times; For the steel ball, diesel engine diesel engine diesel engine engine compression ratio of the height immediately hurt the characteristics of the steel ball, and then give a simple and easy to understand example: Northeast people eat momos and papers, the same can satisfy the stomach, the expected goal is not the same; After a piece of batter wakes up, everyone cuts it in two, one is divided into five small pieces, and then puts it into the steamer to boil, which is the test paper that everyone eats, very loose, just like sliced bread; The other piece is divided into five small pieces, a piece of continuous mild, and then put into the steamer to boil, is everyone's general steamed bun, eating chewy, wheat flavor can be tasted out. This ample shows that the raw material diesel engine diesel engine diesel engine diesel engine compression ratio is how key. It is worth mentioning that the steel ball and the aluminum alloy profile element in the raw material also have a very critical relationship, how much damage is in the end, especially favorite friends, you can see the next phase of the steel ball and aluminum alloy profile association. Companies that understand the history of steel balls will inevitably have the courage to forge ahead with the professional ability of steel balls. With reliable quality and excellent characteristics, at this stage, Illette (see more details) wear resistant steel ball, magnetic plate and other metal composite fiber materials textile raw materials are sold to more than a dozen countries and regions in Asia, Africa, Europe, Africa and other regions, and quickly obtained the recognition of many mining enterprises in the world. And stable in China's steel ball company talent team construction infrastructure projects.
