Abstract

Hot rolling process and hot rolling mill comprising rolling stations (14, 17, 20, 23) of a metallic product (25), wherein in-line heating means (11, 15, 18, 21) perform a heating of the surface zone of the product with respect to the core zone.

IPC Classes  ?

• B21B 37/74 - Temperature control, e.g. by cooling or heating the rolls or the product
• B21B 45/00 - Devices for surface treatment of work, specially combined with or arranged in, or specially adapted for use in connection with, metal-rolling mills

Abstract

Rolling station intended to couple with a respective rolling cartridge or stand provided with two rolling cylinders, wherein the rolling station has a supporting frame of the transmissions suitable for housing a pair of transmission devices of which a first transmission device is intended to couple with a first rolling cylinder and a second transmission device is intended to couple with a second rolling cylinder, the first rolling cylinder being put in rotation by a first motor via the first transmission device and the second rolling cylinder being put in rotation by a second motor via the second transmission device.
