Date Oct. 18, 1990.There is applied on the internal wall of a metallurgical vessel a composition containing a carbonate of an alkaline-earth metal to which there has been added a certain proportion of refractory material in grains and this lining is heated in order to remove CO2 and in order to obtain an oxide layer of the alkaline-earth metal of porous structure. The proportion of refractory material is sufficient to endow the lining with sufficient resistance to erosion by the molten metal which is poured into the vessel. To be used for obtaining a purifying lining having good resistance to erosion from molten metal poured into the vessel.
