摘要: 炼钢厂新建的120 t顶底复吹转炉,通过采用TBM底吹深脱磷技术和新型6孔大流量氧枪,与80 t转炉比较,加快了熔池内钢-渣反应速度,使转炉钢-渣反应更趋于平衡,一倒脱磷率平均提高48.9%,供氧时间平均缩短3.5 min,冶炼周期平均降低5 min;转炉终点(FeO)降低2.93%;钢铁料消耗平均降低1 kg/t。

Abstract: A new 120 t top and bottom combined blown converter with TBM bottom blowing dephosphorization technology and new 6 bore great flow rate oxygen lance is built at steelmaking plant.As compared with original 80 t converter, the speed of reaction between liquid steel and slag increases,the reaction is easily tending towards balance,the average dephosphorization rate increases by 48.9%,the average time of blowing oxygen decreases by 3.5 min,the average tap to tap time reduces by 5 min,the percentage of converter end(FeO) decreases by 2.93% and the average consumption of iron-scrap charging decreases by 1 kg/t.

Key words: Dephosphorization by Bottom Blowing, Great Flow Rate Oxygen Lance, Converter
