Abstract
"MéTODO E APARELHO PARA PRODUZIR FERRO OU AçO". A invenção é um forno de fusão de soleira e acabamento (14) e método de produção de ferro/produção de aço utilizando o forno de fusão de soleira e acabamento. No método, a superfície refratária da soleira (13) é revestida com condicionadores de soleira carbonáceos e compostos refratários e carregada com ferro metalizado pré-reduzido. O ferro metalizado pré-reduzido é liberado, aquecido então até fundir e então reage com carbono e gás de redução até que qualquer óxido de ferro residual seja convertido para ferro que tem um baixo teor de enxofre. A escória nascente se separa do ferro em fusão formando o pepitas de ferro carbonetadas. As pepitas são resfriadas e então as pepitas de ferro e os condicionadores de soleira, que incluem compostos refratários, são descarregados sobre uma peneira (80) que separa as pepitas de ferro dos condicionadores de soleira. Os condicionadores de soleira são reciclados e as pepitas de ferro ou são preparadas para venda ou para tratamento adicional, tal como formação de liga em um forno de fusão final (96).
