摘要：

The use of a nonwetting additive is not always a sufficient solution to improve the corrosion resistance of refractories against molten aluminum. Once in contact with liquid aluminum, the coarse refractory aggregates, which do not benefit from the nonwetting additives in the matrix, may be corroded. In some cases, the corrosion of aggregates promotes corrosion in the surrounding matrix, even in the presence of a nonwetting agent. The present study evaluates the corrosion resistance of 15 aggregates commonly used in monolithic refractories and analyzes their effect within a nonwetting matrix. Based on the experimental results, selecting aluminosilicate aggregates that improve the corrosion resistance of castables to aluminum alloys can be made according to chemical composition.
