Abstract

See full text

Disclosed is a method for producing iron carbide, in which metallic carbide is difficult to be formed on the inside of heating tubes of a tube-shaped heater for heating reducing gas and carburizing gas to be supplied to a reactor. Carburizing gas which is supplied to reactor 1 is heated in tube-shaped heater 6 by combustion gas used for heating reducing gas and circulating gas, and then a mixture comprising carburizing gas, reducing gas and circulating gas is supplied to reactor 1. Iron-containing raw materials are reduced and carburized in reactor 1.
