Method for dephosphorizing molten iron

Abstract

PURPOSE: To effectively execute dephosphorization in molten iron by utilizing converter slag as a part of dephosphorizing agent. CONSTITUTION: After removing desiliconized slag produced with desiliconizing treatment, while blowing iron oxide and slag making agent into the molten iron with carrier gas, the bulky converter slag is added on the molten iron bath to execute the dephosphorizing treatment. By this method, after removing the desiliconized slag, as the converter slag is added on the molten iron bath while blowing the dephosphorizing agent into the molten iron, slopping is restrained and the dephosphorization can be effectively executed.
