Description

Mittel zum Entschwefein flüssigen Eisens. Es ist bekannt, dein flüssigen Eisen in der Gießpfanne ein Entschwefelungsmittel zuzusetzen, und es ist auch schon vorgeschlagen worden, ein Gemisch von Kohle, Kreide und Soda als Entschwefelungsmittel zu verwenden. Durch den Zusatz eines solchen Gemisches wird aber, da die Kohle neben anderen Verunreinigungen auch sehr viel Schwefel enthält, der Entschwefelungsprozeß wesentlich benachteiligt und so nicht der gewünschte Erfolg erzielt.Liquid iron desulphurisation agent. It is known to be your liquid Add a desulfurizing agent to iron in the ladle, and it's already a mixture of coal, chalk and soda has been proposed as a desulfurizing agent to use. By adding such a mixture, however, as the coal is next to other impurities also contains a lot of sulfur, the desulphurisation process significantly disadvantaged and thus not achieved the desired success.

Gemäß der Erfindung wird nun reiner Kohlenstoff in Form von Flockengraphit im Gemisch mit einer Alkaliverbindung als Entschwefelungsmittel verwendet. Hierdurch wird die Entschwefelung im Eisenfluß ohne irgendwelche Apparatur ermöglicht und tatsächlich vollständig erzielt. Beispielsweise wird ein Gemisch von too Gewichtsteilen $oda und 3o Gewichtsteilen Flockengraphit in Pulver- oder Brikettform in der Gießpfanne mit dem möglichst heiß geschmolzenen Eisen versetzt und nach -Beendigung der 6 bis 7 Minuten dauernden Reaktion unter Umrühren mit einem Schlakkenverdickungsmittel wieder abgenommen.According to the invention, pure carbon is now obtained in the form of flake graphite used in a mixture with an alkali compound as a desulphurizing agent. Through this the desulfurization in the iron flow is made possible without any equipment and actually fully achieved. For example, a mixture of too parts by weight $ oda and 3o parts by weight of flake graphite in powder or briquette form in the ladle mixed with the hot melted iron and after finishing the 6 to Reaction for 7 minutes while stirring with a slag thickener removed again.

Das Entschwefelungsmittel kann dem Eisen auch im Kupolofen zugesetzt werden.The desulphurising agent can also be added to the iron in the cupola furnace will.
