Abstract:

Coal blending process and proportioning are determined by means of an experiment on coal blending with modified pitch through 40kg test oven owing to a sound caking property and low ash of the pitch before the coke oven test is done.As a result,the modified pitch is successfully utilized for the uninterrupted production of JN60 coke oven battery.The utilization of coal blending with modified pitch is beneficial to improvement of coke quality,expansion of the range of use and reduction of coke production cost.
