STUDY OF SMELTING REDUCTION RATE FOR VANADIUM TITANIUM MAGNETITE

摘要

A comparative study was made of the reduction kinetics for high temperature smeltingof vadium-titanium-containing magnetite,together with Hainan iron ore,using iron bathmethod.Three peaks were revealed on the reduction rate curves for the magnetite,whileone peak only for Hainan ore.Under the same conditions,the smelting reduction rateof the magnetite was found to be lower than that of Hainan ore.The rate increasesevidently with the increase of the bath volume.The expressions of smelting reductionrate were suggested for the reduction with and without iron bath respectively.
