Abstract

descreve-se um método e um aparelho para pré-aquecimento e fusão redutora de sínter de minério de manganês. o método compreende alimentar a mistura de alimentação (1) contendo sínter de minério de manganês (2), agente redutor (3) e fundente (4) para um forno de arco elétrico submerso (5), fundir a mistura de alimentação (1) para formar uma camada contendo liga de manganês líquido e uma camada contendo escória, remover o manganês líquido e descarregar o gás carbonáceo contendo monóxido de carbono (6), queimar o gás carbonáceo contendo monóxido de carbono (6) na presença de oxigênio, tal como o ar, em um queimador (7) para formar gás carbonáceo contendo dióxido de carbono (9), e aquecer a referida mistura de alimentação (1) em um silo de pré-tratamento (8) antes de alimentar a referida mistura de alimentação (1) para o forno de arco elétrico submerso (5) com o referido gás carbonáceo contendo dióxido de carbono (9).A method and apparatus for preheating and reducing melting of manganese ore sinter is described. The method comprises feeding the feed mixture (1) containing manganese ore sinter (2), reducing agent (3) and flux (4) to a submerged electric arc furnace (5), melting the feed mixture (1). to form a liquid manganese alloy-containing layer and a slag-containing layer, remove liquid manganese and discharge carbon monoxide-containing carbonaceous gas (6), burn carbon monoxide-containing carbonaceous gas (6) in the presence of oxygen, such as air into a burner (7) to form carbon dioxide-containing carbonaceous gas (9), and heat said feed mixture (1) into a pretreatment silo (8) before feeding said feed mixture ( 1) for the submerged electric arc furnace (5) with said carbon dioxide-containing carbonaceous gas (9).
