Abstract

When a low-carbon ferromanganese is produced by blowing an oxidizing gas from a top-blowing lance (3) onto a molten metal surface of a high-carbon ferromanganese in a reaction vessel (1) provided with a top-blowing lance (3) and bottom-blown tuyere (4) to conduct decarburization, the oxidizing gas is blown such that a flow velocity at the arrival at the molten metal surface is 70 m/s or more and 150 m/s or less to conduct refining. Also, agitation is performed under a condition that a agitation power density of a gas blown from bottom-blown tuyere (4) is 500 W/t or more.
