Abstract

"TRATAMENTO SOB VáCUO DE UM METAL FUNDIDO COM MISTURA SIMULTâNEA POR INJEçãO DE HéLIO". A invenção refere-se a um processo de tratamento sob vácuo de um metal fundido sob a forma líquida, compreendendo as etapas que consistem em: introduzir o metal fundido sob a forma líquida em um cadinho metalúrgico que enche esse cadinho até atingir uma altura de proteção compreendida entre 0,4 e 0,6 m, tratar o metal, colocando a atmosfera acima desse cadinho sob depressão e procedendo-se simultaneamente a uma mistura de metal fundido por injeção de hélio no fundo desse cadinho durante uma parte do tratamento ou da totalidade deste.
