Abstract:

This paper introduces the change of process and coke quality after modifying the 4.3m top charging coke oven battery to stamp charging. After the modification,the coke yield has almost remained same as before,while the coke strength at cold and hot conditions has increased,and the coke screening has been improved,the metallurgical coke rate could be increased by 2.5%,coke nut yield has been reduced by 1.5%,and coke breeze yield has been reduced by 0.5%.
