对首钢京唐1号高炉开炉之后的装料制度调整及演变过程进行了分析总结。1号高炉投产以后,通过长时间的摸索,最终建立了适合自身特点的大矿批中心加焦的装料制度,确定了“稳定边沿、打开中心,稳定中心、照顾边沿”的十六字操作方针,实现了中心开放、边沿稳定的煤气流分布。2015年10月—2016年4月,高炉主要技术经济指标达到历史最好水平,其中,平均利用利用系数2.37,日产量13035t/d,焦比275.6kg/t,煤比191.5kg/t。
This paper analyzes and summarizes the adjustment and evolvement process of charging system after the blast furnace of Shougang Jingtang No.1 is opened. After the blast furnace No. 1 was put into operation, a long-term exploration finally established a charging system for large batch of batch coking in accordance with its own characteristics and determined that “the stable edges, open the center, stabilize the center and take care of the edge” Word operation guidelines, to achieve a central open, stable gas flow distribution. From October 2015 to April 2016, the main technical and economic indexes of the blast furnace reached the historical best level. The average utilization utilization coefficient was 2.37, daily output was 13035t / d, coke ratio was 275.6kg / t, and coal ratio was 191.5kg / t.
