The carburization reaction effected the rapid reduction and the separation process by means of the rapid heating of carbon composite iron ore pellets at the high temperatures. Therefore, it was considered that the carbon content of the pellet effects the behavior of this reaction significantly.
While carbon content of the pellet was increased, the melting and separation temperature was decreased. But when atmospheric temperature reached less than 13301380°C, the melting and the separation of metallic iron was repressed though the carbon content was increased. It was considered that this phenomenon was caused by decrease of the carburization speed, which accompanied with the stagnancy of the solution loss reaction and the generation of CO gas.
