摘要/Abstract

摘要： 马钢120 t转炉冶炼洁净钢时,采用≤0,002%S深脱硫铁水、冷料比17%,使用[S]≤0.020%低硫优质废钢,应用烟气分析动态控制技术,转炉终渣碱度3.2～3.5,出钢过程加活性灰600 kg,使终点[S]≤0.008%,提高了终点[C]和温度的命中率,终点钢水活性氧为556×10^-6,吹损喷溅下降,石灰等散装料消耗为≤90 kg/t,钢铁料消耗≤1104 kg/t。

Abstract: As the cleanliness steel was melted by 120 t converter at Masteel,with using ≤ 0.002% S deep-desulphurizing hot metal,cold charge ratio 17%,using[S]≤0.020% low sulphur quality scrap steel,applying off gas analysis dynamic-state controlling technique,controlling converter end slag basicity 3.2～3.5 and adding active lime 600 kg, during tapping,it ensured the end [S] ≤ 0.008%,the percentage of hits for end [C] and temperature increased,the end active oxygen content in steel was 556×10^-6,the blowing melting lose and splashing decreased, the lime etc slag-making material was ≤ 90 kg/t and the charge of iron and steel was ≤ 1104 kg/t.
