ABSTRACT:
A method of slagging off slag, especially treatment slag, from metal baths, particularly iron baths, in vessels such as crucibles and ladles, by means of a rabble while the vessel is slightly tilted. To this end, a slag-free zone starting at the lifted side of the vessel is created by means of a rinsing gas acting on the bath surface on the lifted side of the vessel so that the slag which originally covered the slag-free zone is partially displaced toward the vessel side opposite the slag-free bath surface. The rabble is then lowered onto the slag-free portion of the metal bath and while engaging the slag from behind, the rabble is pushed so as to force the slag over the vessel rim section opposite the slag-free bath surface.
