Characterization and mechanism of dissolution behavior of Al 2 O 3 /MgO oxides in molten slags

Al 2 O 3 - and MgO-based oxides are among the most common oxides in the steelmaking industry. They exist as the main components of refractories, inclusions, or slags. Al 2 O 3 - and MgO-based oxides interact with molten slags continuously during the steel smelting process, which may lead to the dissolution and absorption of the oxides by molten slags, or reactions between oxides and molten slags to form intermediate products. Understanding the dissolution behavior of Al 2 O 3 - and MgO-based oxides in molten slags is important for prolonging the service life of refractories and removing inclusions in molten steel. Therefore, Al 2 O 3 - and MgO-based oxides are considered, and the test methods, dissolution mechanisms, and influencing factors are comprehensively introduced, which can provide a foundation for refractories wear and high-quality steel smelting.
