焦炭M10指标的影响因素分析及改善措施

焦炭M10指标的影响因素有炉型、装煤堆比重、配煤结构、入炉煤细度、熄焦方式等。采用大型焦炉、增加装炉煤堆比重、适当提高入炉煤细度、采取干熄焦方式、高的炼焦终温及合理的配煤结构,有利于改善焦炭质量。济钢6#～9#焦炉采用降低干熄焦故障率、优化配煤结构等措施,焦炭M10指标由6.46%改善到5.99%。

Effect Factors Analysis on M10 Index of Coke and Improvement Measures

The factors affected the M,0 index of coke include cove model, stacking gravity of charging coal, blending ratio, degree of fineness, quenching way etc. Some measures can improve the M10 index such as adopting large coke oven, increasing stacking gravity and degree of fineness of charging coal, taking CDQ, higher coking end temperature and reasonable blending ratio. Through adopting reducing CDQ fault rate and optimizing blending ratio, the M10 of the coke from No.6 to No.9 coke oven was improved from 6.46% to 5.99%.
