For removing deposits from the inner wall of a vessel, for example slag and metal parts from the inner wall of a foundry ladle, or concrete residues from the inner wall of a concrete filling pipe, it is proposed to mill-cut the inner wall, which is considerably more effective and more economical than the working hitherto carried out, using pneumatically driven chisels or by scraping, blasting or striking. |
