Title:
METHOD FOR MANUFACTURING COKE
Document Type and Number:
Japanese Patent JP2019002011
Kind Code:
A
Abstract:
To provide a method for manufacturing high-strength coke by adding a caking agent, where the method maintains the high strength of coke and enlarges coke size even when a blending ratio of non or slightly caking coals is increased.SOLUTION: A method of the present invention is a method for manufacturing coke by charging blended coals comprising coals having highly volatile content in a coke oven and carbonization. The coals having highly volatile content used in the method comprises 30 mass% or more of volatile content and preferably has 50% or more of a caking index. According to the method, adding a caking agent in a liquid state to the coals having highly volatile content in such an amount that mass ratio of the added caking agent to the coals having highly volatile content is more than 5%, mixing, and blending the mixture to other material coals.SELECTED DRAWING: Figure 1
