Abstract
"PROCESSO DE REFINO DE METAL". Um processo de refino de metal particularmente útil com um processo de fabricação de aço com oxigênio, no qual durante um período inicial, o oxigênio de refino é proporcionado para dentro do espaço confinante do forno circundado por um invólucro compreendendo oxigênio e gás inerte, e durante um período subseq³ente o oxigênio de refino é proporcionado para dentro do espaço confinante do forno circundado por um invólucro de chama.
