Abstract

Patente de Invenção: <B>"PROCESSO PARA PRODUçãO DE FERRO GUSA LìQUIDO E/OU PRODUTOS PRIMáRIOS DE AçO"<D>. A invenção refere-se a um processo para produção de ferro gusa líquido e/ou produtos primários de aço a partir de materiais de carga formados por substâncias contendo óxido de ferro e adições se necessário, preferivelmente na forma de peças e/ou péletes, os materiais de carga sendo reduzidos a ferro esponja em uma zona de redução, o ferro esponja sendo fundido em uma zona de fusão gaseificação fornecida com portadores de carbono sólido seco e com gases contendo oxigênio, e sendo gerado um gás de redução contendo CO- e H~ 2-~, o qual é introduzido na zona de redução, é ali convertido e retirado como gás de topo da zona de redução e submetido à lavagem de gás, e se necessário é fornecido a um consumidor como gás de exportação. Utilizando seu calor sensível, o gás de topo retirado da zona de redução submete-se a uma troca de calor com o fluido de troca de calor - antes de gás ser lavado - e portadores de carbono sólido, que se pretende sejam fornecidos à zona de fusão gaseificação, e secos com o fluido de troca de calor aquecido. A invenção também se refere a uma planta para execução do processo.
