Abstract

"PROCESSO DE TRATAMENTO TéRMICO DE TIRA METáLICA". Processo de tratamento térmico de tira metálica que compreende, no interior de um recinto uma passagem da tira através de uma zona de aquecimento do recinto, e de uma zona de resfriamento, e um estabelecimento de uma primeira atmosfera de gás protetor que contém nitrogênio e um primeiro teor em hidrogênio dentro do recinto, com exceção da zona de resfriamento, na qual é ajustada uma segunda atmosfera de gás protetor que contém nitrogênio e um segundo teor em hidrogênio superior ao primeiro, uma introdução de nitrogênio dentro do recinto, uma injeção de gás protetor que contém um terceiro teor em hidrogênio superior ao dito segundo na dita zona de resfriamento, uma troca gasosa entre uma zona do recinto que apresenta a dita primeira atmosfera de gás protetor e a dita zona de resfriamento, e um controle de vazão da dita introdução e da dita injeção.
