Zusammenfassung: | PURPOSE:To eliminate fluorite and soda ash added to promote the melting of lime in dephosphorizing treatment. CONSTITUTION:In the dephosphorizing method of molten iron for blowing oxygen gas by putting dephosphorizing agent on the molten iron, line stone is used as >=40% of the lime source for the dephosphorizing agent. By this method, without adding the fluorite and the soda ash, high dephosphorizing ratio can be achieved and the dephosphorizing cost is reduced. |
