Sažetak

Hot metal pretreatment desulfurization is an important way in metallurgical industry, and Mg as a desulfurizer is widely used in the steel industry. In this paper, magnesite based desulfurizer that the ratio is 63 % MgF₂, 12 % CaF₂,18 % NaF and 7 % MgO is used and at the molten iron temperature, magnesite based desulfurizer molten salt system is electrolyzed and the counter electromotive force and cell voltage is measured. The results of X-ray diffration(XRD) analysis of the desulfurization reaction products show that the counter electromotive force and the cell voltage of the magnesite desulfurizer is linear with current; MgO is electrolyzed and generated Mg, but other substances are not electrolyzed; The generated Mg is successfully desulfurized. All those indicated that it is feasible for magnesite based desulfurizer electrolytic desulfurization at the temperature of molten iron.
