Abstract
In a process for working up combustion residues and slags from waste incineration plants or steel works slags, the slag is charged at a slag layer height of above 1.2 m into a converter (1), in which the molten slag is reacted with a metal bath (4) through which oxygen is blown. The oxygen is introduced into the bath (4) for cooling the submerged tuyeres (7, 8) in the form of air or along with CO.sub.2 or water vapor.
