| Abstract Scope |
Due to the characteristics of converter slag, compared with blast furnace slag, it cannot be widely used in the building materials industry, which is an important issue for the development of Chinese steel companies. This paper uses FACTSage thermodynamic calculation software to study the conversion of converter slag by using the heat of blast furnace slag, and the research results provide a theoretical basis for improving the utilization rate of converter slag. The thermodynamic calculation results show that the molten blast furnace slag can absorb the free CaO and MgO in the slag through a variety of eutectic phase and peritectic phase melting reactions, and melt part or all of the high melting point Ca2SiO4; When the proportion of blast furnace slag is relatively high, the fluidity of the mixed slag can be maintained, which provides a guarantee for subsequent processing. |
