摘　　要：首钢京唐1#(5 500 m^3)高炉在总结长期生产经验的基础上,通过稳定原燃料质量、优化装料及送风制度、适当提高富氧水平、强化低硅冶炼等措施,提高炉内焦炭负荷,提高煤比。通过优化实践,2017年1~4月高炉焦炭负荷稳定在5.5以上,焦比280 kg/t,煤比193 kg/t,高炉产量维持在13 000 t/d以上,实现了高炉重负荷大煤比冶炼。Based on the long-term production experience,the coke load and coal ratio of Shougang Jingtang 1#（ 5 500 m^3） blast furnace were increased by stabilizing the fuel quality,optimizing charging and air supply system,improving oxygen level and strengthening lowsilicon smelting. The blast furnace heavy load and large coal ratio smelting has been realized by practice optimization with coke load stable at more than 5. 5,coke rate 280 kg/t,coal rate 193 kg/t,and blast furnace output more than 13 000 t/d.
