Abstract:

By coal analysis and coke property test,the possibility of Xinzhou-produced gas coal replacing Fengfeng 1/3 coking coal is studied, including the best proportion.The test result shows that the Xinzhou-produced gas coal is an ideal substitute of Fengfeng 1/3 coking coal, its usage proportion is preferably controlled within 6% when the coke strength in hot state drops down very little,which can ensure a supporting bed in blast furnace.
