A method for adjusting an inlet guide of a peeling machine controls a peeling material using the inlet guide in relation to a peeling head carrying peeling tools in such a way that the volume per unit length of the peeling material, which volume is to be machined by the peeling machine, is minimized while producing a bright steel having excellent surface quality. Furthermore, a peeling machine provides appropriate measuring equipment in order to be able to carry out the method described above.

The invention relates to an apparatus (10) for the thermal treatment of metallic products, which comprises (a) a support and transport plane (24); (b) at least one collector module (12) comprising at least one collector (14, 16), the collector (14) being provided with a perforated plate (22) facing the support and transport plane (24); (b-2) a conduit (20) connected to said at least one collector (14), and (b-3) integrated in said conduit (20), at least one stop valve (18). The stop valve (18) is situated at a distance from the collector (14) which does not exceed 60 cm. The perforated plate (22) is provided with holes which are arranged in rows parallel to each other but not in parallel rows with respect to the sides of said perforated plate. The rows are inclined with respect to two opposite sides of the plate (22) of an acute angle.

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.
