轴承钢研究现状及发展趋势

Research status and development trend of bearing steel

中国近年来工业制造领域不断发展,这对国内轴承钢的研发制造提出了新的挑战,高品质轴承钢的研发生产成为当前国内轴承行业亟待解决的问题之一。从轴承钢的分类、性能的主要影响因素以及热处理工艺的发展等方面对国内外轴承钢的研究进展进行了综合论述,提出了发展国内高品质轴承钢需解决的工艺优化、夹杂物与碳化物的控制、检测设备及技术评价指标缺乏等问题的方法,以期实现国内高品质轴承钢的量化生产与应用。

The continuous development of China′s industrial manufacturing field in recent years has posed new challenges to the research,development and manufacturing of domestic bearing steel.The development and production of high-quality bearing steel has become one of the urgent problems to be solved in the domestic bearing industry.The research progress of bearing steel at home and abroad is comprehensively discussed in terms of the classification of bearing steel,the main influencing factors of bearing steel performance and the development of heat treatment technology and so on.In order to realize the quantitative production and application of domestic high quality bearing steel,the methods of process optimization,control of inclusions and carbides,lack of testing equipment and technical evaluation indexes for the development of high quality bearing steel in China are put forward.
