Abstract

Patente de Invenção: <B>''MéTODO PARA RECICLAR LAMAS POSSUINDO FERRO EM UMA OPERACãO DE FABRICAçãO DE AçO''<D>. A invenção é direcionada a um processo para desidratar lama úmida de depurador de BOF para produzir uma reversão de fabricação de aço que tem uma taxa de escoamento aperfeiçoada quando manipulada em uma corrente de reciclagem. Lama úmida é combinada com escória quente de BOF para prover uma mistura de escória/lama. A lama úmida causa a mistura de modo a ter um teor de umidade maior do que 10% de água em peso, e a escória quente que tem uma temperatura abaixo do estado líquido fundido, vaporiza a água na mistura e reduz o teor de umidade para aproximadamente 4% de água em peso ou menos. A mistura desidratada tem propriedades de taxa de escoamento aperfeiçoadas quando ela é reciclada como uma reversão de fabricação de aço.
