摘　　要：河北钢铁集团承钢公司因资源特点采用提钒—炼钢双联工艺生产模式,钒钛磁铁矿冶炼过程中铁水硫含量较高,在镀锌板冶炼过程中LF脱硫任务较重,不能抑制回硅,造成硅含量超标,影响冶炼合格率。通过采取控制原料、酸溶铝含量,加强挡渣操作等措施,很好地解决了SPHC回硅问题,提高了硅成分合格率。Based on the resource feature,the duplex process of vanadium-extracting and steelmaking is adopted in Cheng Steel.The LF desulphurization is one important task in smelting process of zinc-plating steel because of rather high content of sulphur in hot metal in smelting of vanadium titano-magnetite,and so resiliconization can not be restrained and silicon content surpasses the standard to influence qualified smelting ratio.With raw material controlled,strengthening slag stopping operation and acid-solved aluminum control,the SPHC resiliconization is well controlled and qualified silicon content ratio increased.
