Abstract

Laminador con cilindros oblicuos, de 2 cilindros, para la fabricación de bloques huecos de aceros de alta aleación con herramientas guía para el material laminado, que cierran la zona de transformación con el taladrado del bloque hueco en sentido transversal al eje de los cilindros, en el que las herramientas guías se componen respectivamente de un cuerpo base que se compone de un material soporte, y un material que forma la superficie de trabajo con propiedades antiadherentes para aceros con una fuerte aleación y una gran resistencia térmica, caracterizado porque el material de la superficie de trabajo es de molibdeno o de una aleación con base de molibdeno, y porque el espesor de la superficie de trabajo se elige de forma que los valores de la expansión de calor de la pieza de trabajo y del cuerpo base en la superficie de contacto a la temperatura de trabajo son casi iguales.
