Abstract

as invenções se relacionam ao campo de metalurgia, e, especificamente, a um método para produção de aço e a um projeto de uma fornalha de arco elétrico para implementação do mesmo. o método envolve carregamento de uma carga em um espaço de operação de uma fornalha, referida carga consistindo de sucata de metal e de materiais de oxi-carbono aglomerados, admissão de energia elétrica, combustível, um carburizador, um fluxo e oxigênio gasoso, aquecimento e derretimento da carga usando arcos elétricos com a descarburização de um banho de metal, e liberação de metal e escória a partir da fornalha. antes do derretimento, uma porção dos materiais de oxi-carbono é carregada, simultaneamente com uma primeira porção de carga de metal, na zona central da fornalha, e os materiais de oxi-carbono remanescentes são introduzidos na carga derretida durante o processo de derretimento a uma velocidade de carregamento específica de 0,5 ? 10 kg/min por 1 megavolte-ampére de energia do transformador da fornalha de arco elétrico, e o tamanho das peças de materiais de oxi-carbono é selecionado para ser entre 5 e 80 milímetros. as paredes do alojamento da fornalha são providas com pelo menos três aberturas, que são espaçadas ao longo do perímetro destas, para carregamento de materiais de oxi-carbono na zona central da fornalha, cujas aberturas são providas 0,2-1,0 metros abaixo do nível de uma marca superior no alojamento da fornalha. a invenção torna possível reduzir o consumo específico de eletricidade quando do derretimento da carga de metal, aumentar a saída de ferro dos materiais de oxi-carbono, e também aumentar a quantidade relativa de referidos materiais na massa total de carga.
