据1987年国际炼钢会议文集报道优质轴承钢,特点是高碳铬的轴承钢,主要靠电弧炉和小型铸锭方式进行生产,近期连铸也开始变得日趋普遍。神户公司用降低钢中总氧及钛、硫含量和改善中心偏析等的方法提高了钢材抗反复接触疲劳的寿命,因此,神户生产的高纯优质轴承钢首先得到日本官方承认。神户用铁水预处理,氧气顶吹和在钢水
According to the 1987 International Steelmaking Symposium, high-quality bearing steel is reported, featuring high carbon-chromium bearing steel, mainly produced by means of electric arc furnaces and small ingots. In the near future, continuous casting has also become more and more common. KOBE Corporation has raised the life expectancy of steel against repeated contact fatigue by reducing total oxygen and titanium in steel, sulfur content, and improving center segregation. Therefore, high-quality, high-quality bearing steel produced in Kobe was first officially recognized by Japan. Kobe pre-treated with hot metal, oxygen top blowing and in molten steel
