Experimental Research on Influencing Factors of Melting Reduction for High-Phosphorus Titanomagnetite Pellets

Abstract

Reduction of high-phosphorus titanomagnetite was studied for future comprehensive utilization of resource. Experimental temperature (T), burden alkalinity (CaO/SiO2) and carbon-oxygen ratio (C/O) had an influence on the content of [P] and [S] in hot metal. Highest dephosphorization rate in hot metal appeared at C/O=1, high temperature was beneficial to desulphurization, but not for dephosphorization. High CaO/SiO2may decrease the content of [P] and [S]. C/O and CaO/SiO2had great influence on the content of [P] and [S] in hot metal.
