摘要
承钢公司长材事业二部120 t炼钢系统采用BOF→LF→CC工艺流程,通过控制碳、硅、硫含量,以及LF冶炼后的酸溶铝含量,减少连续浇铸过程中的二次氧化,成功冶炼CDCO3钢,解决了生产中硅含量超标、钢水可浇性差的问题,铸坯的低倍质量均满足用户要求。
In 120 t steelmaking system of No. 2 Long- Materials Business Department of Cheng Steel,with BOF- LF- CC process flow,controlling contents of carbon,silicon and sulfur as well as content of acid-soluble aluminum after LF smelting,reducing the secondary oxide in continuous casting,CDCO3 steel is successfully smelted,the problems in production of silicon content being over standard and cast- ability being bad solved,the macro quality of casting billet can meet demand of customers.
