PRODUCING METHOD OF LOW-PHOSPHORUS HIGH-CARBON FERROMANGANESE AND LOW-PHOSPHORUS MEDIUM/LOW-CARBON FERROMANGANESE, CAPABLE OF MINIMIZING THE LOSS OF MANGANESE

摘要

PURPOSE: A producing method of low-phosphorus high-carbon ferromanganese and low-phosphorus medium/low-carbon ferromanganese is provided to economically produce the low-phosphorus high-carbon ferromanganese with the high purity.;CONSTITUTION: A producing method of low-phosphorus high-carbon ferromanganese comprises the following steps: inserting a high carbon ferromanganese molten metal to a decarbonization puddling furnace and adding oxygen gas to perform the decarbonization; stopping the insertion of the oxygen gas, and adding carbon dioxide gas and BaO for the dephosphorization; and removing slag.;COPYRIGHT KIPO 2011
