Abstract：Molten steelmaking slag produced during converter steel-making process contains a large amount of heat energy and chemical energy. It can be used to react with water vapor for H2 production to realize the effective recycling for the energy in metallurgical process. In this paper, the generation of H2 was proved by experiment and the effects of slag compositions on H2 production were analyzed by FactSage. It turns out that, the ion current of H2 increased from 0 A to 8.4×10-9A immediately at the begining of reaction and the weight of slag increased by 0.091 g during reaction. FeO content and the increasement of slag basicity (W(CaO)/W(SiO2)) are beneficial to obtain more H2. The change of MnO content in slag has little effect on H2 production and the amount of Al2O3 has negative effect on H2 production.
