Abstract

Ein Mittel zur Entschwefelung und/oder Vorentschwefelung insbesondere von Roheisenschmelzen oder Stahlschmelzen enthält Calciumoxid sowie Bitumen. Optional enthält das Mittel zusätzlich Magnesium oder eine Magnesiumlegierung, Fliessmittel und ein Additiv. Zur Herstellung des Mittels werden die Komponenten zermahlen. Das Mittel wird unter Verwendung von Transportgas, durch ein Einrührverfahren oder in Form eines oder mehrerer Briketts zur Entschwefelung und/oder Vorentschwefelung und/oder Schlackenkonditionierung in die Roheisenschmelze bzw. Stahlschmelze zugegeben.
