Abstract

"SISTEMA PARA A PRODUçãO DE AçO". A presente invenção se refere a um dispositivo para a produção de aço, que compreende um recipiente (1, 101, 201). O metal usado é fundido, refinado e afinado no recipiente mencionado que compreende uma parte superior (5, 205) contendo no mínimo uma abertura, através da qual eletrodos (21) são carregados para dentro do recipiente com uma parte inferior (2, 202) assim como meios para sangrar a massa fundida e a escória de dentro do recipiente. O objeto da invenção é aprimorar o mencionado dispositivo de modo que a construção deste seja mais simples em comparação com os dispositivos já conhecidos. Está previsto um sistema de sangria pelo fundo (10, 11) para a sangria da massa fundida e eventualmente da escória.
