Abstract

Patente de Invenção: <B>"MéTODO E INSTALAçãO PARA PRODUZIR UMA FORNADA DE FERRO USANDO MATERIAIS RESIDUAIS DE INSTALAçãO DE FUSãO REDUTORA"<D>. Método para produzir uma fornada de ferro, usando-se materiais residuais de instalação de fusão redutora contendo ferro para efetivamente reprocessar materiais residuais de instalação de fundição redutora (1 a 3) nos quais o ferro pode estar presente tanto na forma metálica quanto na forma de óxido com o menor gasto possível de energia, os materiais residuais de instalação de fusão redutora (1 a 3) são processados em aglomerados (8, 11), os aglomerados (8, 11) são carregados em um forno elétrico a arco (10), fundidos lá e reduzidos, e a fornada resultante é refinada (Figura 1).
