Claims (1)

<Desc/Clms Page number 2> <Desc / Clms Page number 2> 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass ein oxydierendes Gas vom Boden des das Stahlbad aufnehmenden Behälters her und gleichzeitig in einer höheren Ebene des Stahlbades ein reduzierendes Gas in das Stahlbad eingeleitet wird. 2. The method according to claim 1, characterized in that an oxidizing gas from the bottom of the container receiving the steel bath and at the same time a reducing gas is introduced into the steel bath in a higher level of the steel bath. 3. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass vom Boden her ein reduzierendes Gas und in der höheren Ebene ein neutrales Gas, das mindestens teilweise durch verdampfte oder vergaste Halogene bzw. deren Verbindungen ersetzt sein kann, in das Stahlbad eingeleitet wird. 3. The method according to claim 1, characterized in that a reducing gas and in the higher level a neutral gas, which can be at least partially replaced by vaporized or gasified halogens or their compounds, is introduced into the steel bath from the bottom. 4. Verfahren nach Anspruch 2, dadurchgekannzeichnet, dass als ein oxydierendes Gas ganz oder zum grössten Teil in einer unter dem das Stahlbad aufnehmenden Behälter (1) angeordneten Brennkammer (4) mit Sauerstoff verbranntes Kohlenmonoxyd dem Stahlbad zugeführt wird. 4. The method according to claim 2, characterized in that carbon monoxide burned with oxygen is fed to the steel bath as an oxidizing gas wholly or for the most part in a combustion chamber (4) arranged under the container (1) receiving the steel bath.
