Abstract:
A process for producing iron carbide from granular, directly reduced iron obtained from the reduction of iron ore, which comprises supplying granular, directly reduced iron ore to a carburizing reactor and forming a fluidized bed of at least a part thereof in said carburizing reactor, supplying a liquid hydrocarbon to said reactor at a temperature of from 500Â° C. to 900Â° C. vaporizing said liquid hydrocarbon in said carburizing reactor and reacting the vaporized hydrocarbon with the fluidized directly reduced iron at a temperature of 580Â° C. to 700Â° C. to form a product comprising from 5 to 90% wt. iron carbide, and withdrawing at least a part of said product from said carburizing reactor.
