Abstract

PURPOSE: To obtain coke for metallurgical purpose, having a high coke strength, by the procedure in which a bituminous substance which softens and melts at a temperature below the softening point of coal and has an ability to raise the density of powdered coal is added to powdered coal, and then the powdered coal is mixed with pressed coal and subjected to carbonization.
CONSTITUTION: In order to raise the bulk density of powdered coal in a low-temperature range below the softening point of coal, 0.3W15wt% a bituminous substance of a softening point of less than 100°C and a fixed carbon content of 10wt% or more is added to the powdered coal, and then the powdered coal so treated is mixed or kneaded with a pressed coal manufactured by compressive molding, pelletization, etc., in such an amount that non- or less coking coal (or) carbonaceous content becomes greater than the powdered coal and then subjected to carbonization to obtain coke for metallurgical purpose.
