Abstract (en)

[origin: WO9011853A1] A composition containing an alkaline-earth metal carbonate together with a certain concentration of refractory grain material is applied to the inner wall of a metallurgical container. Said coating is then heated so as to eliminate the CO2 and obtain an oxide layer of said alkaline-earth metal with a porous structure. The concentration of refractory material is sufficient to ensure that the coating is able to withstand the erosion of the liquid metal cast in the container. Use: for obtaining a purifying coating with a high resistance to erosion.
