Abstract

PURPOSE: To reform charging coal of low caking capacity to coke of high coke strength for the titled purpose by the procedure in which powdered coal is sorted out, a bituminous substance is added to fine coal powder to form coal lumps, and the coal lumps are mixed with the remaining small coal particles and carbonized.
CONSTITUTION: Powdered coal is sorted out by flashing, screening, etc., to obtain fine coal powder portion, and 0.3W15wt% a bituminous substance of an H/C ratio of approx. 0.51W1.14 preferably is added to the fine coal powder portion and then made into lumps by heating up to 300°C or less as needed by pseudo-granulation by using high-speed rotary mixer, a compressive molder, or a dish-type granulator. Then, the lumpy fine coal powder portion is mixed with the remaining small coal particle portion and then subjected to carbonization to obtain coke for metallurgical purpose.
