摘要
酒钢120 t转炉采用双渣法少渣冶炼工艺,其氧气单耗平均降低1. 01 m3/t,供氧时间缩短0. 25 min,总渣量减少6. 64 kg/t,降低转炉石灰消耗17%,终渣磷分配比可达到90. 45,冶炼时间比正常冶炼工艺长2 min左右。该工艺是对炼钢工艺的改进,对优化炼钢工序、成本降低具有重大意义。
This paper introduces the use of double slag method and less slag steelmaking process in the 120 t converter of JISCO.The oxygen consumption is reduced and blowing time is shortened,the total slag volume is reduced by 6.64 kg/t,the lime consumption of the converter is reduced by 17%,and the final slag phosphorus distribution ratio can be reached 90.45,the smelting time is about 2 minutes longer than the normal smelting process.This process is an improvement of the steelmaking process and is of great significance for optimizing the steelmaking process and cost reduction.
