摘要
Refractory linings of metallurgical vessels, such as a tundish lined with alumina brick, are protected from the destructive effects of molten metal, skull, and skull removal by applying a coating of special refractory parting composition to the metal-contacting interior surfaces of the refractory lining. The coating is applied after skull removal and prior to returning the vessel to service. The special refractory parting composition consisting of a mixture of chrome ore, periclase, and a magnesium salt, and the particle size distribution are compounded to adhere to the solidified metal of the skull, to be non-adherent to the refractory lining, and to crumble on skull removal to the extent necessary to prevent injury to the refractory lining.
