To accurately control the Si content and ensure the function of slag refining in high aluminum steel, the direction and limits of reduction reaction for SiO2 were analyzed based on the thermodynamics. In addition, the thermodynamic prediction model of multi-element slag was studied. Then, a slag activity prediction model was established based on the coexistence theory. Using the model, the suitable ladle slag composition for high aluminum steel was calculated.
The effects of the cooling rate on a new type CaO–Al2O3–B2O3–CaF2-based mold flux for high aluminum steel casting were investigated using CSLM and a high temperature tube furnace.
