    The RH vacuum treatment deep desulfurization premelting slag for ultra-low-carbon steel comprises: 48~56% CaO, 33~43% Al2O3, 0.2~5.0% MgO, 2.5~6.0% SiO2TiO21.9, C0.05 and impurity, and is prepared by electric melting the material of super 60-65% limestone and 35-40% Al2O3 powder (Al-content more than 96%). This invention improves desulfurization capacity, produces Ca(AlO2)2 convenient to preserving, and has little corrosion to RH groove.
