Abstract

Patente de Invenção: "ANODO DE AQUECIMENTO DE PLASMA TRANSFERIDO". Anodo de aquecimento de plasma transferido para aquecer um metal derretido em um recipiente com a aplicação de um plasma de Ar gerado com a passagem de uma corrente contínua através do metal derretido, o anodo de aquecimento de plasma transferido compreendendo um anodo, composto de um metal condutivo, que apresenta uma estrutura de resfriamento interna, um protetor de metal que dispõe de uma estrutura de resfriamento interna que é colocada no lado de fora do anodo com uma abertura constante entre o anodo e o protetor, e um meio de suprimento de gás que supre um gás contendo Ar à abertura, é caracterizado pelo fato da porção central na superfície externa da extremidade do bico do anodo ser rebaixada para dentro.
