摘　　要：随着汽车电动化发展,对汽车用齿轮钢提出了窄淬透性、超低氧含量、成分均质化、夹杂物无害化控制等新要求。鉴于此,某钢厂采用“超高功率电炉→LF→VD→CC”工艺,通过电炉氧化性控制、精炼夹杂物无害化工艺生产、连铸防二次氧化等操作,批量生产出高疲劳强度的汽车用齿轮钢。With the development of automotive electrification,new requirements such as narrow hardenability,ultra low oxygen content,composition homogenization and inclusion harmless control are put forward for automotive gear steel.In view of this,the process of"ultra-high power electric furnace→LF→VD→CC"of a steel plant is adopted to produce high fatigue strength automotive gear steel in batch through such operations as electric furnace oxidation control,refining inclusion harmless process production and continuous casting anti secondary oxidation.

关 键 词：齿轮钢 超纯净 夹杂物
