Abstract

Procedure for hot rolling of metal bars made especially of steel, preferably of a circular cylindrical basic shape, with projections or depressions periodically arranged in rows, characterized in that during hot rolling of the bar they are rolled in the last rolling passes, in a first operation, projections or depressions arranged in two rows facing each other, whose center lines are in a common plane perpendicular to the axes of the cylinders, and then in a second operation projections or depressions are arranged that are arranged in a second pair of rows facing each other whose center lines are in a common plane perpendicular to the cylinder axes and which is offset by 90º with respect to the plane in which the center lines of the rolled rows are found in the first operation, avoiding in the second operation a contact with the formator of the c illindros with the projections or depressions of the rows already laminated in the first operation.
