Abstract：On the basis of analyzing the features of a characteristic coal, the coking test was done replaced part of fat coal and gas coal in 40 kg small coke oven and 4.3 m top charge coke oven. The results showed that the characteristic coal instead of fat coal proportioning control within 20%, the coke quality change is not big, hot strength improves somewhat. With 10%-15% of the characteristic coal instead of fat coal and coking coal in top charge coke oven is feasible. Blending 10%the characteristic coal and relevantly reducing fat coal 8%and gas coal 2%produced metallurgical coke with high strength level (M40=84.3%, M10=84.3%, CRI=23.5%, CSR=69.7%), and reduced the cost of coal blending 19.1 Yuan/t.
