Abstract

eletrodo de autocozimento, e, pasta de eletrodo. é provido um eletrodo de autocozimento que pode ser usado como um eletrodo em um forno elétrico usado para produzir ferrocromo de baixo teor de carbono. o eletrodo de autocozimento (10) é formado pelo preenchimento de um revestimento cilíndrico (11) com uma pasta de eletrodo (12), e sinterização/solidificação da pasta de eletrodo (12) por aquecimento joule por condução de eletricidade e pelo calor condutivo do forno elétrico. a densidade de corrente do revestimento é ajustada para 100a/cm2 a 400a/cm2, abrangente, e o eletrodo de autocozimento (10) é usado como um eletrodo em um forno elétrico usado para produzir ferrocromo de baixo teor de carbono.self-baking electrode, and electrode paste. A self-baking electrode is provided which can be used as an electrode in an electric furnace used to produce low carbon ferrochrome. the self-baking electrode (10) is formed by filling a cylindrical coating (11) with an electrode paste (12), and sintering/solidifying the electrode paste (12) by joule heating by electrical conduction and by the conductive heat of the electrode. electric oven. the current density of the coating is adjusted from 100a/cm2 to 400a/cm2, comprehensive, and the self-baking electrode (10) is used as an electrode in an electric furnace used to produce low carbon ferrochrome.
