上钢五厂生产轴承钢已有20多年的历史,在国内享有一定声誉。最近几年在消化吸收国内外先进技术的基础上,又研制成功HB—40钢包精炼轴承钢工艺。该工艺的特点是:利用钢包中加热、吹氩搅拌和真空脱气等操作来完成脱氧、脱氢,去硫、去夹杂、合金化和调整温度等任务,从而获得纯洁度
Steel Plant on the production of five bearing steel has 20 years of history, enjoy a certain reputation in the country. In recent years, based on the digestion and absorption of advanced technologies at home and abroad, the successful development of HB-40 ladle refining bearing steel technology. The process is characterized by the use of ladle heating, argon blowing and vacuum degassing and other operations to complete the deoxidation, dehydrogenation, desulfurization, to inclusions, alloying and temperature adjustment and other tasks, so as to obtain the purity
