Abstract

Método y su correspondiente aparato para determinar la temperatura de una barra metálica que penetra en la segunda fase de un tren de laminación continuo en caliente que incluye una primera fase y una mesa de retardo para conducir la barra desde la primera fase hasta la segunda fase, incluyendo dicha mesa de retardo una porción abierta y un bobinador en el cual se sitúa dicha barra durante un período de tiempo determinado mientras la barra pasa desde la primera fase hasta la segunda fase, estando dicho método caracterizado porque incluye las operaciones que consisten en: determinar la temperatura de la barra a su salida de la primera fase de dicho tren de laminación; determinar el tiempo durante el cual la barra está presente sobre la parte abierta de la mesa de retardo; calcular la reducción de temperatura de la barra cuando está en la parte abierta de la mesa de retardo; determinar el tiempo durante el cual la barra está presente en la porción de bobinador de la mesa de retardo; calcularla reducción de temperatura de la barra cuando está en el bobinador; y sustraer de la temperatura de la barra determinada a su salida de la primera fase del tren de laminación, las reducciones de temperatura que se producen mientras la barra está en la porción abierta y en la porción de bobinador de la mesa de retardo para obtener una temperatura de barra destinada a ser utilizada para determinar la temperatura de la barra a su entrada en la segunda fase de dicho tren de laminación.
