摘要
当前,应用于高速铁路、大型风电、轧机的高端轴承产品主要失效形式为破裂、剥落、接触疲劳等。这些都与轴承钢的冶金质量密切相关,特别是氧含量与非金属夹杂物级别水平。本文从轴承钢的种类、洁净度的主要影响因素以及生产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,归纳了高洁净轴承钢需解决的工艺优化、夹杂物与碳化物及化学成分的控制等问题的方法。
At present, the main failure modes of high-end bearing products used in high-speed railways, large-scale wind power plants, and rolling mills are rupture, spalling, and contact fatigue. These are closely related to the metallurgical quality of bearing steel, especially the oxygen content and the level of non-metallic inclusions. In this paper, the research progress of bearing steels at home and abroad is summarized from the aspects of the types of bearing steels, the main factors affecting the cleanliness and the development of production technology, etc. The methods of process optimization, the control of inclusions, carbides and chemical composition for high clean bearing steels are summarized.
