(1)钢中碳、硅的控制。LF工艺精炼中采用含碳材料脱氧、石墨电极升温及强还原性气氛等因素,很容易使钢水增碳、回硅。 (2)LF精炼脱氧、脱硫的负担重。由于铁水本身含硫较高,转炉冶炼R380CL(正)时,钢水终点碳低、氧高。转炉提供的高硫、高氧钢水,使得LF精炼脱氧、脱硫的负担加重。 (3)可浇性问题。R380CL(正...

LF精炼是把转炉或电炉氧化末期钢水,倒入钢包炉并去掉氧化渣50-90%,加还原渣料及脱氧剂,以便进行还原精炼。若适当增加加热下的搅拌时间、渣量及搅拌功率,出钢时除渣100%则可进一步降低钢中的硫含量,使[%S] <30ppm及[%O] <20ppm,使钢液成为洁净钢。

LF精炼低硅钢时,会使钢水[Si]出格,影响钢水成分的合格率。增硅影响因素是: 1、元素含量 精炼时反应方程式为4[Al]+3(SiO2)=2(Al2O3)+3[Si].低[Al]会使钢水脱氧不良,高[Si]会使钢水出格,而只有降低(SiO2)含量,增加(Al2O3)含量来实现降低[Si]。
