Open publisher page 0 citations

Abstract

This work has developed a new desiliconization flux mainly made of the converterslag and the blast furnace manganese slag. At 1733 K, when the quantity of the flux is 5%of thequantity of hot metal, desiliconization rate can reach 75%～80%and oxidation of Mn is under0.1%。 The thermodynamic and technological conditions of the protection of Mn duringdesiliconization treatment have been discussed.
