Abstract

INSTALAÇÃO E PROCESSO DE PRÉ-AQUECIMENTO DE UMA CINTA DE AÇO EM PASSAGEM CONTÍNUA. A presente invenção refere-se a uma instalação e a um processo de pré-aquecimento de uma cinta de aço em passagem contínua, em partincular antes de sua introdução em um forno de re cozimento contínuo ou de galvanização na têmpera. A instalação de pré-aquecimento prevê que a cinta de aço esteja em passagem contínua em um compartilhamento de pré-aquecimento, compreendendo um circuito de pré-aquecimento constituído de pelo menos um tubo de pré-aquecimento, cuja superfície interna está em contato com gases queimados de recuperação externa (por exemplo, do forno). Uma Parte da superfície externa desse tubo de pré-aquecimento é disposta em vista direta de uma superfície da cinta, assegurando um primeiro modo de pré-aquecimento por radiação térmica sobre a cinta e as paredes do compartimento, e um se gundo modo de pré-aquecimento, majoritariamente por convecção, de um gás que constitui uma atmosfera controlada no compartimento de pré-aquecimento.
