摘要
介绍了重型卡车驱动桥齿轮用SCM822H钢的技术要求;石钢公司采用转炉初炼、LF+VD精炼、连铸连轧、缓冷生产工艺,通过窄成分控制,满足了用户的窄淬透性带要求,钢的质量均达到标准要求。
The technical demand of SCM822H steel for the gear of drive axle of heavy vehicle is introduced. The steel is developed in Shi Steel with process of primary smelting with converter, refining with LF＋VD, continuous casting and continuous rolling, slow cooling.Besides with narrow composition control it meets the requirement of customers for narrow band of hardenability and the quality of steel all reaches the demand of standard.
