摘　　要：为提高焦炭热态性能 ,济钢焦化厂利用小焦炉试验和大工业焦炉试验 ,确定了主焦煤矿点及适应 175 0m3大高炉用焦的配煤结构 :1/3焦煤 2 5 %、肥煤 2 5 %、焦煤 3 5 %、瘦煤 15 % ,与原生产配比相比 ,焦炭热态反应性平均降低 4.6% ,反应后强度平均提高 4.3 %Through making experimentations in small-scale and industry coke oven, the coal blending system for 1750m^(3)BF is made certain. The system is composed of 1/3 coking coal of 25%, rich coal of 25%, coking coal of 35 % and carbonaceous coal of 15%. Compared with the original blending, the coke's hot performance is reduced by 4.6%, the cold performance is increased by 4.3% averagely.
