METHOD FOR PRODUCING FERROCOKE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing ferrocoke which prevents cracking and thermal cracking caused on carbonization of a molded product to raise the yield of the original shape at the outlet of a carbonization oven in carbonizing the molded product composed of an iron oxide-containing substance and a carbonaceous substance-containing substance to produce the ferrocoke and is hard to crack on introducing the ferrocoke into a blast furnace to enable prevention of the lowering of yield. SOLUTION: The method of producing ferrocoke by carbonizing by heating the molded product obtained by mixing the iron oxide-containing substance and the carbonaceous substance-containing substance and molding the mixture comprises setting the heating rate in the temperature range of the surface temperature of the molded product of 550-650°C at not higher than 20°C/min to perform the carbonization.
