Abstract

INSTALAçãO PARA A TRANSFORMAçãO SECA DE UMA ESTRUTURA DO MATERIAL DE PRODUTOS SEMI-ACABADOS. A presente invenção refere-se a uma instalação para a transformação seca de uma estrutura do material de produtos semi-acabados, especialmente para a bainitização seca, com uma câmara de têmpera, e uma câmara de transformação da estrutura disposta de maneira subseuúente no fluxo de processamento, sendo que cada vez um espaço interno de ambas as câmaras, pelo menos durante a respectiva etapa de processo para a transformação da estrutura do material, está solicitada com sobrepressão de gás. A instalação destaca-se pelo fato, que são previstos meios para a manutenção de uma sobrepressão mínima do gás que atua sobre o produto semi-acabado, durante uma transferência do produto semi-acabado da câmara de têmpera para a câmara de transformação da estrutura.
