The effects of coal charge properties,coking technological condition and additives on the initial reaction temperature of coke were investigated through coke-making blend coal test.The results show that,the initial reaction temperatures of both single coal and blended coals go up along with the increase of coalification degree of the coals.With the extension of soaking time,the initial reaction temperature increases.With the improvement of coal fineness,the initial reaction temperature goes up slightly.Howe...
