Abstract

resumo “método para operação de alto forno e método para produção de ferro gusa fundido” fornecido é um método de operação de alto forno incluindo: uma primeira etapa de ajustar uma taxa de carregamento de coque durante o monitoramento de uma temperatura de topo de forno ttop; uma segunda etapa de ajustar uma taxa de injeção de carvão pulverizado enquanto monitora uma velocidade de gás em alto forno superficial u eo forno-top temperatura ttop; uma terceira etapa de ajuste de uma relação de oxigênio-enriquecimento de ar enriquecido com oxigênio durante o acompanhamento de uma temperatura de combustão tf e a temperatura de topo do forno ttop; e uma quarta etapa de determinar se uma taxa de injecção de ar enriquecido em oxigênio precisa ser ajustada, com base em um valor da velocidade superficial u do gás no forno.
