Dissolution of alumina in stainless stee

Dissolution of alumina in stainless steelmaking slags was studied by conducting laboratory scale experiments on typical slags in the temperature range 1823-1923 K. The mechanism of dissolution was examined under actual steelmaking conditions where phenomena such as simultaneous reduction of chromium, iron, and vanadium oxides by carbon, in-situ gas generation due to the reduction, and foam/emulsion formation occur. The kinetics of alumina dissolution were investigated, considering the effect of these phenomena. The results highlight the importance of understanding the dissolution kinetics of solid oxides, which is crucial for the life of refractories in steelmaking processes. Various investigations have previously addressed alumina's dissolution behavior in different types of molten slags, showing that factors such as composition and temperature significantly influence the dissolution rate. This study contributes to the existing body of knowledge by providing detailed insights into the dissolution process of alumina within a more complex steelmaking environment, offering practical implications for improving refractory materials used in these processes.
