Magnesium oxide castable refractory foundry ladle liners

摘要

Refractory foundry ladle liners made from castable magnesium oxide-based compositions are disclosed. The liner compositions include MgO-containing aggregate, Al₂O₃-containing aggregate, and an inorganic binder. The ladle liners are cast into shape, placed into ladle shells, and packed with sand. The foundry ladle assemblies, including the pre-cast MgO-based ladle liners, are reusable for multiple foundry operations.
