Abstract:

The properties of domestic 10 kinds of coal for cokemaking and 6 kinds of Australian coal are described. Coal blending experiment is carried out on the basis of single coal study and analysis, and test and industrial test are done with Australian coal to replace domestic coal. The result of experiment shows that when Australian PDC coal is used to replace 25% Jiexu coking coal, coke strength after reaction is improved by 13% and cold crushing strength by 2%.
