METHOD AND APPARATUS FOR ROLLING TUBES, ESPECIALLY IN STRETCH-REDUCER, NON-PELINING OR CONTINUOUS LAMINATORS

摘要

The present invention relates to a method and a device for rolling tubes, in particular in stretch-reducer, pilgrim, or continuous rolling mills, in which, before the rolling process and / or during the rolling process. rolling, a desired temperature distribution, modifying, by zone, the resistance to deformation of the tube is set in the laminated material. BR/ - According to the invention, in the device, after the rolling mill (5), a multi-channel radiographic apparatus (1) is provided for measuring the wall thickness of the outgoing tube (4), the value of which measurement, after treatment, can be brought into a computer (2) as a signal of a heating and / or cooling device (3). / P
