Abstract

"ESTRUTURA DE FUNDO PARA UM FORNO DE FUNDIçãO". A invenção refere-se a uma estrutura de fundo de um forno de fundição em suspensão a ser utilizada em um forno de fundição (1); onde, no espaço reacional (2), é fundida uma matéria prima sulfítica contendo metal, tal como cobre, níquel ou chumbo na presença de um gás contendo oxigênio e de um agente formador de escória, de maneira a tornar o metal em uma forma vantajosa para tratamentos posteriores, e onde as fases fundidas criadas (5,6) são sedimentadas sobre o fundo (3) do forno de fundição de forma a separar as fases fundidas umas das outras, quando a temperatura das fases fundidas está na faixa de 1150 - 1450<198>C. De acordo com a invenção, a estrutura de fundo inclui pelo menos uma camada de revestimento arqueada (7) inclinada na direção longitudinal do forno de fundição de tal forma que a temperatura na superfície (8) oposta à superfície que entra, em contato com a fase fundida seja abaixo de 800<198>C.
