Abstract
Rodillo de laminación en caliente para barras de cobre térmico, uso del mismo y procedimiento de laminación asociado, siendo el rodillo de laminación del tipo diseñado para rotar alrededor de un eje de rotación y vinculable a un contra-rodillo de laminación tal que se permite el paso de la barra entre ambos, estando dotado el rodillo de laminación con al menos una banda de rodadura que comprende a su vez una acanaladura anular para el paso de la barra, presentando la acanaladura anular una sección transversal que comprende una base opuesta a una embocadura, en el que la base comprende una porción paralela al eje de rotación, presentando la base en su porción paralela una anchura que es por lo menos la mitad de la anchura de la embocadura, siendo ambas anchuras paralelas al eje rotación.Hot rolling roll for thermal copper bars, use thereof and associated rolling procedure, the rolling roll being of the type designed to rotate about an axis of rotation and linkable to a counter rolling roll such that the passage of the bar between the two, the laminating roller being provided with at least one tread band which in turn comprises an annular groove for the passage of the bar, the annular groove presenting a cross section comprising a base opposite an embouchure , in which the base comprises a portion parallel to the axis of rotation, the base having in its parallel portion a width that is at least half the width of the mouth, both widths being parallel to the axis of rotation.
Description
El laminado en caliente se desarrolla siempre a temperaturas superiores a 2/3 veces la temperatura de fusión del metal laminado que en el caso del Cu son los 800 ºC (1073 K); y a velocidades de deformación en el rango 0,5 a 500 1/s (porcentaje por segundo). El límite inferior de temperatura de laminado viene determinado por el punto en el cual el ritmo de Hot rolling always develops at temperatures greater than 2/3 times the melting temperature of the rolled metal which in the case of Cu is 800 ° C (1073 K); and at deformation rates in the range 0.5 to 500 1 / s (percentage per second). The lower limit of rolling temperature is determined by the point at which the rate of
5 recristalización del metal es suficientemente rápido para eliminar el endurecimiento por deformación que se produce en el proceso de laminado. The metal recrystallization is fast enough to eliminate the strain hardening that occurs in the rolling process.
