Abstract

Los materiales a laminar que varían de diámetro grande a pequeño se someten a un laminado de reducción de diámetro con una excelente precisión dimensional del diámetro exterior. Una laminadora incluye tres o más rodillos de laminación (2) alineados a lo largo de una dirección circunferencial y dispuestos de tal manera que cada eje giratorio de los mismos esté sesgado con respecto a una línea de paso (P) de un material a laminar (1), en donde el material a laminar (1) hecho de un material de tubo o barra se hace pasar entre los tres o más rodillos de laminación (2) mientras se gira para someterse a un laminado de reducción de diámetro. Al menos un rodillo de laminación (2) seleccionado de los tres o más rodillos de laminación (2) tiene un diámetro de rodillo más pequeño que al menos otro rodillo de laminación (2). Cuando, entre los tres o más rodillos de laminación (2), al menos un rodillo de laminación (2) que tiene un diámetro de rodillo relativamente máximo se define como un rodillo de laminación de diámetro máximo (2A) y al menos un rodillo de laminación (2) que tiene un diámetro de rodillo más pequeño que el rodillo de laminación de diámetro máximo (2A) se define como un rodillo de laminación de diámetro pequeño (2B), el rodillo de laminación de diámetro pequeño (2B) tiene un diámetro de rodillo igual o menor al 90% del diámetro de rodillo del rodillo de laminación de diámetro máximo (2A).
