METHOD OF ADJUSTING THE PROFILE OF DISPLACABLE CYLINDERS IN A ROLLING MILL AND IMPROVED ROLLING MILL FOR IMPLEMENTING THE METHOD

摘要

The object of the invention is an axially displaceable roll mill, comprising, a support cage 4, at least two working rolls 1, 1 'and at least two support rollers 2, 2', at least 1 one of the working cylinders 1 being associated, on the one hand with means 42 for moving said cylinder 1 along its axis 10, and on the other hand for each chock 3, two symmetrical assemblies of at least two cylinders of bending 6, 66. BR/ According to the invention, the offset of the cylinder 1 is continuously measured with respect to a centering position and the pressure exerted by each bending cylinder 6 is adjusted at each instant, according to the measured offset and the position at the same time of the jack 6 considered relative to the median plane P5 of the bearing 12, so that the resultant bending forces exerted by all the cylinders 6, 66 remains directed at each moment , according to the median plane P5 of the bearing 12, the bending cylinders take are supported on the chocks via sliding faces.
