Abstract

PURPOSE: To manufacture a coke for metallurgical purpose economically, by a method in which a desired amount of high-carbon briquettes is uniformly mixed with a compounding coal for manufacturing coke and then subjcting the mixture to a carbonization.
CONSTITUTION: A substance rich in fixed carbon, e.g., oil coke, is ground, mixed with a coal or petroleum binder, e.g., coal tar, asphalt, etc., in an atmosphere of overheated steam of approx. 140W170°C, cooled, and then molded by compression of approx. 50kg/cm2 (preferably 150W300kg/cm2) at approx. 60°C into briquettes having a volume of 1W100cc (preferably 10W30cc) per one briquette. Then, a desired amount of said briquettes is mixed uniformly with a compounding coal and then the mixture is subjected to an usual carbonization to obtain a coke with adhered high-carbon dense briquette of a porosity of approx. 15% which is used for metallurgical purpose.
