Improved bearing material smelting technology to improve the uniformity of steel

Improved bearing material smelting technology to improve the uniformity of steel
Compared with the industrialized countries, the oxygen content of bearing steel has been close though foreign advanced level, but the carbide size, inclusions, uniformity and composition uniformity compared to the gap with foreign countries is still very large, such as said large size of the inclusions and carbides are more, because the basic ingredients resulting in uneven formation of black and white areas, so that the bearing part quality, but off a serious impact on bearing life, reliability and consistency.
Furthermore, the rolling contact surface of the large size of the presence of inclusions, the surface accuracy is severely degraded, the bearing noise increases. Therefore, the bearing manufacturer industry and metallurgical industry must negotiate, promoting nearly metallurgical industry in reducing the oxygen content, based on the rolling technology, casting solidification technology, inclusions control and testing technology research carried out together, such as improved when casting electromagnetic stirring, to increase the size of the slab, to enhance high-temperature diffusion annealing, etc., to improve carbide inclusions and the uniformity of size and distribution.Bearing in our industry has been greatly developed, the position occupied is also very important, however, is the development of the bearing when we have to glimpse at the development of two major drawbacks of the bearing, which can avoid the risk, the better development of the industry, China's bearing market is mainly the following two questions, the first is that we are not very strong capability of independent innovation, China's many industrialized products are through imitation, if we can independently developed a number of industrial products, so it will not appear some of what technology monopoly problem, nor will our development by others. At the same time if we independently developed something for our production environments require industrial products, then more in line with our situation, and secondly is our brand building is not perfect, many of our tapered roller bearing companies are paying attention to brand building, however, did not too much to pay attention to how to sell yourself, a good brand is not spelled out, but a product to stand out in a constant practice to use the technology also quality, only the technology and quality is excellent, people will remember this brand will give a high evaluation, tapered roller bearings which are usually separated type, it is widely used in mining and automotive, plastics machinery industry, our friendship promote products: class 7 bearings, tapered roller bearings, If interested, welcome to buy
