Abstract

"PROCESSO E DISPOSITIVO PARA EXTRAIR METAIS EM FUSãO DE RECIPIENTES DE FUSãO METALúRGICOS". A fim de se evitar que, durante a extração de um metal em fusão (2) de um recipiente metalúrgico (5) dotado de um orifício de extração (10) disposto no fundo do recipiente (13), seja arrastada simultaneamente com o metal em fusão ou subseq³entemente a escória em fusão (1), consoante a invenção é proposto se eliminar a escória em fusão (1) da superfície do metal em fusão (2), na região do orifício de extração (10), por insuflamento de um jato de gás (9) com alta energia de impulso.
