Abstract

Gas coal, 1/3 coking coal, anthracite and lean coal are used to blend coal, asphalt is used as binder, coal blending scheme is formulated according to the requirements for each index of coal blending. The best scheme of coal blending is: 35% of the lean coal is combined with 30% 1/3 coking coal, 20% gas coal, 5% anthracite and 10% bitumen. Under this scheme, the various indexes of the formed coke are: the ash content is 11.91%, the sulfur content is 0.41%, the volatile matter content is 1.47%, the crushing strength is 98.93%, the wear-resistant strength is 1.07%, the compressive strength is 10.83MPa, which is accord with the national metallurgical coke grade one standard.
