Abstract

Abstract

A complex desulfurizer and its application to the desulfurization of hot metal by pneumatic injection were discussed. Using CaC₂ mixed with the supplemental reactants, the rate of desulfurization was the same as that of pure CaC₂.Operational results show that the average desulfurization rate was 90.45%,the average final S content in the hot metal 0.0065% and the average temperature loss of hot metal 19℃, while the average initial S content in the hot metal was 0.071% and the average desulfurizer consumption 8.08kg/tFe. The effect of desulfurization was the same as the level of KR process.
