Abstract

"PROCESSO DE TRATAMENTO TERMOQUìMICO CONTìNUO DE TIRAS METáLICAS". Processo de tratamento termoquímico contínuo de tiras metálicas, notadamente de aço, do tipo óxido-redução, de acordo com o qual a tira se desloca através de um forno em uma atmosfera protetora, caracterizado pelo fato de que a dita tira passa através de pelo menos um dispositivo de isolamento parcial ou total, posicionado no centro de pelo menos uma seção do forno, ou entre duas seções, a tira sendo aquecida, neste dispositivo de isolamento, em atmosferas com ponto de orvalho adaptado a cada tira em função da composição especifica do aço, de maneira que a atmosfera seja oxidante para certos elementos de adição, mas permanece redutora para o ferro.
