Abstract (en)
[origin: EP2233548A1] The present invention provides a method of producing ferrocoke capable of, in carbonizing a molded product composed of a carbon-containing material and an iron oxide-containing material to give the ferrocoke, preventing cracking and thermal cracking occurring in carbonizing of the molded product, increasing the original form ratio at the carbonizing furnace discharge side, preventing cracking in charging the ferrocoke into the furnace and also preventing reduction of a yield. Specifically, used is the method for producing ferrocoke by heating a molded product composed of a mixture of a carbon-containing material and an iron oxide-containing material to carbonize the molded product, in which carbonization is performed at a heating rate of 20 °C/min or less in a temperature range where a temperature of a surface of the molded product ranges from 550 °C to 650 °C.
