<p>The invention relates to a process for increasing scrap addition in converter processes by preheating of scrap in the converter (1) and to a converter (1) with preheating burners above the bath level (6). Especially in order to allow good flame control and coverage of the whole surface of the scrap column, it is proposed that uncooled parallel-jet annular-gap burners (7) or long-slot burners (8) with natural gas (10) feed on the outside and oxygen feed (12) on the inside are arranged on opposite sides around the spigot in the lower region (4) of the converter (1) above the bath level (6) of the stagnant liquid molten metal.</p>
