在铸坯断面与浸入式水口型式一定的前提下，考虑塞棒吹氩流量、浇注速度、水口浸入深度三因素对结晶器流场的影响，针对IF钢生产，制定了3种FC结晶器工艺参数试验方案，并进行了试验，通过对IF钢板夹杂情况进行了统计分析，摸索出最佳的FC结晶器工艺参数为：浇注铸坯断面为230 mm×1400mm的 IF钢，正常浇注速度在1.35～1.40m/min，FC结晶器上线圈工作电流为＋240A; 下线圈实际工作电流为－274A。
On the precondition of the steady slab dimension and the SEN mode,It is considered of the influence about the stopper red argon flow rate、casting speed、SEN immerging depth on the mould fiow field,According to the IF steel production,Three type of testing project of the different technical parameter of FC-mould is established, and try on ,Analyzing the non metallic inclusions of IF sheet, The optimal technical parameter of FC-mould of IF steel was fish out:the slab dimension is 230×1400mm2 , casting speed is 1.35～1.40m/min,the up coil working current of FC mould is ＋240A; the down coil working current of FC mould is －274A.
