Abstract

EN UN PROCESO DE CALENTAMIENTO DE MATERIAL METALICO EN FORMA DE MADEJA (2), POR EJEMPLO, ALUMINIO EN MADEJAS, POR PASO GRADUAL A TRAVES DE VARIAS ZONAS DE CALDEO (A, B, C) DISTRIBUIDAS EN HILERA UNA TRAS OTRA, CONTROLABLES POR SEPARADO, AJUSTADAS CADA UNA DE ELLAS A UNA TEMPERATURA TEORICA Y SUPERVISADAS MEDIANTE UNA VARILLA DE MEDIDA. EL MATERIAL METALICO EN MADEJA (2), TRAS ALCANZAR LA TEMPERATURA PREFIJADA, ES TRANSPORTADO HACIA ADELANTE PARA CORTAR UN BLOQUE DE LONGITUD X LA DISTANCIA A+X, RETROCEDIENDO DESPUES DEL CORTE LA DISTANCIA A. A ES LA DISTANCIA ENTRE EL EXTREMO ANTERIOR DEL MATERIAL METALICO QUE SE ENCUENTRA EN LA ULTIMA ZONA DE CALENTAMIENTO (D) ANTES DEL AVANCE Y LA CIZALLA (3). EN ESTE PROCESO SE TOMAN, AL MENOS EN LA PRIMERA ZONA DE CALENTAMIENTO (A), LAS TEMPERATURAS DE LA SUPERFICIE DEL METAL ANTES DEL AVANCE A TRAVES DE LAS VARILLAS DE CONTROL, ASI COMO EN UN PUNTO ENFRENTADO SITUADO LA DISTANCIA L HACIA ATRAS, SIENDO L (MAYOR O IGUAL) X. PARTIENDO DE ESTAS DOS MEDICIONES DE TEMPERATURA SE DETERMINA ELGRADIENTE DE TEMPERATURA. A PARTIR DE AHI SE AVERIGUA EL RENDIMIENTO DE CALDEO Y SE HACE QUE SE ALCANCE LA TEMPERATURA TEORICA TRAS EL AVANCE DE LA DISTANCIA A+X Y EL RETROCESO DE LA DISTANCIA A AL MENOS EN EL PUNTO DE MEDICION DE LA PRIMERA ZONA DE CALENTAMIENTO. LA POTENCIA DE CALENTAMIENTO NECESARIA SE PUEDE CALCULAR A PARTIR DE ESTAS MEDICIONES PARA LA O LAS SIGUIENTES ZONAS DE CALENTAMIENTO, PUDIENDO SER DE GRAN AYUDA LA DETERMINACION DE UN GRADIENTE DE TEMPERATURA ENTRE LOS PUNTOS DE MEDICION DE ZONAS CONTIGUAS DE CALENTAMIENTO.
