Outline
In this paper, the influencing factors of coking coal in hot performance test are analyzed and they are mainly reflected in the process of smelting coke with coking coal, sample preparation method of coke and the hot performance test process of coke. The effects of the process of smelting coke with coking coal on hot performance of coke are mainly reflected in type of test coke oven, temperature control program, coal capacity, density of coal charge and mode of quenching coke. Sample preparation is a key operation in the hot performance test for smelted coke and its influence on test values is significantly. With other conditions the same, the stability of test values for hot performance test of coke with pure handmade sample is the best, but the values are higher. The effects of test process on hot performance of coke are mainly reflected in the number of sample, flat-temperature zone of oven, thermocouple of temperature control, reactant gas and standard screen.
