Abstract:

Statistical method is adopted to study the relationship between the coke fine recovery rate under blast furnace trough and consumption of coke stored on the ground,coke transfer and average grain size,so as to determine the key factors influencing the average grain size of metallurgical coke. The result is taken to guide the production operation of coke oven battery and optimize the storage and transfer of coke. Coke fine recovery rate under blast furnace trough can be reduced and the average grain size of charging coke is improved.
