摘　　要：大冶钢厂50t高功率电弧炉—60t VAD精炼生产的轴承钢可完全除去对轴承钢疲劳寿命危害最大的D类夹杂物,得到较低的B类夹杂评级和较低的氧含量,使轴承钢内在质量的主要指标达到世界先进水平。采用计算机对精炼过程进行控制可得到低而稳定的氧含量。The harmful inclusion of grade D on fatigue life of ball steel can be eliminated by HP EAFVAD process. The ball steel of lower/inclusion of grade B with lower oxygen has been obtained, which guality has attained to the world advanced level. This success is achieved under computer control for refining process.
