Abstract

Patente de Invenção:<B>"FORNO DE RECOZIMENTO TIPO CAIXA, MéTODO DE RECOZIMENTO DE CHAPA FINA METáLICA QUE UTILIZA O MESMO, E CHAPA FINA METáLICA RECOZIDA"<D>. Um forno de recozimento do tipo caixa para recozer uma chapa fina metal inclui uma unidade de remoção de oxigênio para remover oxigênio da atmosfera em um forno de recozimento do tipo caixa, com um sistema de circulação de gás para retirar atmosfera do forno de recozimento do tipo caixa durante o recozimento, tratar o gás, e para realimentar o gás desoxidado ao forno de recozimento do tipo caixa. O forno de recozimento do tipo caixa pode incluir ainda uma unidade de remoção de unidade para remover umidade do gás. A unidade de remoção de oxigênio e a unidade de remoção de umidade podem confiavelmente remover oxigênio e umidade do gás e suprimir a formação, durante o recozimento, de película de óxido sobre a chapa fina de metal ferroso.
