Abstract

Procedimiento de reducción de los pliegues formados en zonas de calentamiento, mediante tubos radiantes, de líneas de tratamiento térmico en continuo de bandas metálicas, tales como líneas de recocido o de galvanización, pasando las indicadas bandas, por los indicados hornos sobre unos rodillos de transporte y/o de reenvió, caracterizándose el indicado procedimiento que consiste en modificar el estado térmico de los rodillos porque la indicada modificación se realiza directamente por modulación del calentamiento de los indicados tubos radiantes (4) situados en la proximidad de los rodillos (2), controlando directamente el flujo térmico emitido por los tubos radiantes hacia los rodillos.
