<p>In a process for heating within a ladle (5) steel melts (10) being covered with a slag (8) rich in iron oxides, in particular for continuous steel production processes such as, for example, the KVA-process, thereby using metallothermal heat, there is (are) during filling the ladle (5), insufflated by an inert gas via nozzles (14) provided in the bottom (12) of the receiving ladle (5) for the mixture of bath and slag a metal, such as, for example, Al, Si, their mixtures or alloys, in particular FeSi, exothermically reacting with the oxygen of the bath and with the oxygen of the slag as well as, optionally, pulverulent slag formers, such as, for example, CaO, Al2O3, MgO and/or SiO2.</p> |
