Abstract

Procedimiento de mejora de la producción de una línea vertical de tratamiento térmico del acero o del aluminio y/o de mejora de la calidad de los productos que se van a tratar por reducción de los pliegues formados dentro de una cámara (1; 1') de calentamiento o de refrigeración para una banda metálica (3; 3') que pasa sobre rodillos de transporte y/o de reenvío que equipan dicha cámara, con una determinación de las tolerancias de las temperaturas de la banda aceptables para una no formación de pliegues sobre los rodillos, en régimen estable o transitorio, caracterizado por un cálculo en tiempo real del perfil en caliente del o de los rodillos (2; 2') los más críticos para la formación de pliegues, y un cálculo en tiempo real de la temperatura de la banda máxima admisible para el o los perfiles en caliente calculados para el dicho o dichos rodillos los más críticos, dichos cálculos estando efectuados por referencia a por lo menos un modelo físico integrado de intercambio térmico que incluye al menos los intercambios conductivos entre la banda (3; 3') y los rodillos (2; 2') de la cámara (1; 1') de calentamiento o de refrigeración.Procedure for improving the production of a vertical line of heat treatment of steel or aluminum and / or improving the quality of the products to be treated by reducing the folds formed within a chamber (1; 1 ') of heating or cooling for a metal band (3; 3 ') that passes on transport and / or forwarding rollers that equip said chamber, with a determination of the tolerances of the temperatures of the acceptable band for a non-formation of folds on the rollers, in stable or transient regime, characterized by a real-time calculation of the hot profile of the roller (2; 2 ') the most critical for the formation of folds, and a real-time calculation of the temperature of the maximum permissible band for the hot profile (s) calculated for the said or said most critical rollers, said calculations being made by reference to at least one integrated physical model of inte thermal exchange that includes at least the conductive exchanges between the band (3; 3 ') and the rollers (2; 2') of the heating or cooling chamber (1; 1 ').
