In this paper,the influence of different cokemaking processes on coke quality between top-charge battery and stamp-charge battery is studied.Based on actual production,the coke qualities by the two processes with different coal blending compositions are analyzed.The result shows that the stamp-charge cokemaking can obviously improve the abrasion resistance (M10) and coke strength after reaction (CSR),but has little improvement of coke reactivity index (CRI).The crushing strength of coke (M40) could be possibly improved or degraded,it depends on the proportion of premium coking coal and fat coal.
