Zusammenfassung:For melting scrap, iron sponge pellets in the reduced form, solid pig iron or the like, it is proposed to supply the melting heat by means of burners from below and, without additions of coal to the charge, to set a corresponding carbon content in the molten bath by less than stoichiometric combustion of hydrocarbons. At the same time, the aggressivity of the slag is diminished by reducing the oxygen flow, especially by combustion with approximately 0.9 times the stoichiometric quantity of oxygen, and, if appropriate, an addition of slag formers.
