Abstract

Patente de Invenção:<B>"MéTODO PARA TRATAMENTO TéRMICO DE MATERIAL LAMINADO E DIPOSITIVO PARA REALIZAR O MéTODO"<D>. Método para tratamento térmico de material laminado deixando um trem laminador (12), onde o material laminado (13) sofre um tratamento com rápido resfriamento em uma montagem de rápido resfriamento (11) localizada imediatamente a jusente da última passagem de laminação, a primeira etapa de resfriamento sendo seguida por uma etapa de igualação de temperatura no ar e pelo menos por um segundo tratamento de resfriamento antes de ser descarregado e coletado, a etapa de igualação de temperatura no ar e pelo menos o segundo tratamento de resfriamento sendo estabelecidos de modo a não modificar a superfície e a estrutura interna cristalina do material laminado (13) que formou-se na saída do primeiro tratamento de resfriamento, pelo menos o segundo tratamento de resfriamento sendo segudo por um curto segmento de igualação de temperatura no ar e depois diretamente pela coleta do material laminado (13) em forma compacta, tal como rolos, bobinas, maços ou pacotes, onde o lento resfriamento do material laminado (13) coletado em forma compacta leve à transformação da estrutura cristalina nas estruturas estáveis. Dispositivo para tratamento térmico de material laminado realizando o método como descrito acima.
