Abstract:

On the basis of blending more anthracite for coke making,a 40kg pilot coke oven is used to study the optimum coal blending ratio to produce coke with high CSR.The result shows that with 30%~40% anthracite and 50%~55% coking coal and fat coal blended,the stamp-charging coke oven can produce coke with CSR higher than 60%,and both the mechanical strength and CSR of coke meet the requirement of first class metallurgical coke.
