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 Cylindrical roller 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 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.When the center of gravity of global manufacturing shift to China at the same time gradually, not only promoted China's economic development, a lot of people to solve the employment problem for our high-end bearing cast this
Development of the industry to provide a strong impetus, the focus of global manufacturing shift to China is also gradually on China's high-end manufacturer of bearings manufacturers a higher technology to
Requirements. Currently China's bearing industry must cast the parts industry is stepping up consumption while reducing costs more because of the technology to enhance their gold content, so that we produce bearings
Will have a market competitive, we have to keep the focus on improving product quality grades and lower the cost of manufacturing costs, will gradually form their own style will be gradually formed from
"Big" to "strong" strategic transformation of the mode. Of China's machinery manufacturing industry has its own set of production style, which is why we move towards the international market a strong guarantee, but in the
We gradually sell yourself at the same time, we still have to continue to strengthen their scientific and technological innovation, so we can bring to the domestic industry more development of the platform.
