Abstract

A method for producing medium- or low-carbon ferromanganese is provided. The method makes it possible to produce medium- or low-carbon ferromanganese having a low nitrogen concentration and a low silicon concentration. Also, medium- or low-carbon ferromanganese having a low nitrogen concentration and a low silicon concentration is provided. Molten high-carbon ferromanganese is charged into a reaction vessel equipped with a top-blowing lance and bottom- blowing tuyeres. The molten high-carbon ferromanganese is subjected to decarburization refining to be converted to molten medium- or low-carbon ferromanganese, the decarburization refining being carried out by injecting an oxygen-containing gas over the molten high-carbon ferromanganese through the top- blowing lance and injecting an inert gas into the molten high- carbon ferromanganese through the bottom-blowing tuyeres. The molten medium- or low-carbon ferromanganese is poured into a mold and cooled to produce medium- or low-carbon ferromanganese, the cooling being performed in a manner such that a temperature of a surface of the medium- or low-carbon ferromanganese becomes 800?C or lower within 15 minutes after completion of the decarburization refining, the surface being a bare surface in the mold.
