Description

Thebes.

The invention relates to the processing of metals by pressure, in particular to rolling equipment, and can be used in vertical or universal stands of a rolling mill.

The purpose of the invention is to increase the service life of the rolls and thereby reduce the number of rolls transshipments due to the maximum possible use of the surface of the barrel of the vertical roll by its vertical movement relative to

rolling level.
