摘要

超低氧含量和低夹杂物级别是高品质轴承钢的重要指标。分析了高品质轴承钢中超低氧含量和非金属夹杂物控制的影响因素

如出钢除渣、铝脱氧、高碱度精炼渣、真空或非真空条件下的长时间搅拌和合理的生产工艺流程等。得出生产5×10

的超纯净高品质轴承钢的关键是对各冶炼工序的严格控制。文中分析了国内轴承钢的质量并提出了研究方向。

Abstract

The ultra-low-oxygen content and low rating of inclusions are key indexes for high quality bearing steel. The influence factors on control of ultra-low-oxygen content and nonmetallic inclusions in high quality bearing steel are analyzed including removal of slag during tapping

deoxidation with aluminium

high basicity refining slag

stirring for long time at vacuum or atmosphere

and available process flow sheet. It is obtained that the key factor to produce ultra-clean high quality bearing steel with 5 x 10

is strict control of each steelmaking procedure. The quality of bearing steel produced at home is analyzed and the research orientation for high-quality bearing steel is put forward.
