摘　　要：采用变量法精确确定了吨钢入炉铁水量调整后转炉系统的热量亏空,通过优化调整转炉造渣物料结构,减少强冷却效果物料的使用量,配加反应速度快、升温效率高的碳-硅质发热剂,稳定解决了吨钢铁水量降低所带来的转炉系统热量不足的问题,提高了入炉废钢比。在工业生产顺行的基础上,80 t转炉入炉铁水量由860 kg/t钢降低到800 kg/t钢。The variable method is used to accurately determine the heat deficit of the converter system after the adjustment of the hot metal quantity of ton-steel.By adjusting the slag making material structure of the converter,reducing the material consumption with strong cooling effect,and adding carbon silicon heating agent with fast reaction speed and high heating efficiency,the insufficient heat of the converter system caused by the reduction of hot metal consumption is stably solved,and the scrap ratio is increased.Based on the smooth operation of industrial production,the amount of hot metal in 80 t converter is reduced from 860 kg/t to 800 kg/t.
