Abstract
Disposición de ajuste para la regulación del grado de estiramiento global de un laminador reductor con estiramiento de muchas cajas para la reducción por estiramiento de tubos, con el cual, para conseguir un espesor de pared terminado de tubo permanente y deseado, se puede ajustar el grado de estiramiento en función de mediciones efectuadas por el lado de entrada de los espesores medios de pared de los tubos, caracterizada porque está prevista una unidad calculadora, la cual a partir de los espesores de pared y de los diámetros exteriores, tanto de los tramos de tubo realmente entrantes como también de los tramos de tubo terminados deseados, calcula discontinuamente los estiramientos nominales, y a partir de las velocidades de entrada y de salida de los tubos calcula continuamente los estiramientos reales, y porque en un circuito de regulación está presente un regulador que ajusta los números de revoluciones de los rodillos en función de las diferencias entre los estiramientos nominales y los estiramientos reales.
