Abstract: An apparatus and method of applying a lubricating material to an outer surface of a workpiece. Initially, a workpiece is provided that is preferably formed from a closed channel structural member having a circular or box-shaped cross sectional shape. Lubricating material is applied to an outer surface of the workpiece. In a second step of the method, the workpiece may be heat treated.

Abstract: The invention is directed to a hot-rolling process and a hot-rolling mill for metal strips (5) having one or more roll stands with work rolls (1, 2).
