1.前言钢材的冶金质量是影响轴承寿命的关键因素之一,而钢中非金属夹杂物的数量、分布、类型和尺寸大小是轴承钢冶金质量的重要指标。大量的研究结果表明氧化物夹杂对钢的接触疲劳寿命有明显不良的影响。在冶炼过程中,尽可能降低钢中氧化物含量,提高钢的纯洁度是近一个世纪以来炼钢工作者
1. Introduction The metallurgical quality of steel is one of the key factors affecting bearing life. The quantity, distribution, type and size of non-metallic inclusions in steel are important indexes of metallurgy quality of bearing steel. Numerous studies have shown that oxide inclusions have a significant adverse effect on the contact fatigue life of steels. In the smelting process, as much as possible to reduce the oxide content of steel, improve the purity of steel is steelmaking workers in the past century
