Abstract
A workpiece drive for rotating a circular workpiece in a descaling device has a carrier and at least three support roller modules. Each of the support roller modules has a bearing and a support roller for the circular workpiece. The support roller has a longitudinal axis, a lateral surface and a radius between the longitudinal axis and the lateral surface, and the radius decreases in a longitudinal direction along the longitudinal axis. The bearing supports the support roller rotatably around the longitudinal axis. Each of the support roller modules has a drive and the drive is designed to rotate the support roller around the longitudinal axis. The bearings are arranged on the carrier in such a way that the longitudinal axes have a point of intersection and lie in a plane perpendicular to the earth gravity field vector and such that the longitudinal directions are directed towards the point of intersection.
