Abstract:

This essay discusses the influence of coking period to coke quality by changing the coking period of 5.5 stamped charging battery, provided that the coal blending ratio is constant. The result shows that by suitably extending coking period, coke anti-crush strength and coke strength after reaction can be efficiently improved, anti-wearing strength and reactivity of coke can be improved, sulfur content in coke can be reduced, and charging cost can be reduced by blending more poor coking coal.
