Abstract: A method of producing steel with the lowest possible desired sulfur content by desulfurization of pig iron with magnesium coke. The magnesium coke is introduced into the pig iron smelt which is to be desulfurized. An inert gas such as nitrogen is then introduced into the smelt to agitate same until the magnesium is completely reacted. The thus treated smelt is subjected to subsequent inert gas rinsing in order to separate magnesium sulfide from the smelt and convey to into the slag formed on the smelt. A slag-free area is then produced on the surface of the smelt by introducing inert rinsing gas on the surface. Slag powder is introduced upon the exposed surface of the smelt to form a cohesive, viscous slag, which is then withdrawn. Scrap iron having suitable high or low sulfur content may be introduced into the desulfurized pig iron to adjust the desired sulfur content thereof.

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.
