Abstract
1. Process for refining a metal bath containing substantial quantities of solid cooling matter, in particular scrap metal, which provides for a refining operation through blowing of oxygen from the top on to the surface of the bath and introducing powdered carbon suspended in a neutral gas jet into the bath, said jet being directed on to the bath surface, characterized in that a velocity of the order of Mach 1.5 to Mach 2.5 is imparted to the jet and in that a quantity of neutral gas is injected simultaneously into the bath, through permeable elements lodged in the bottom of the vessel, which is sufficient to prevent foaming of the slag under the effect of the added carbon.
