Abstract

For rolling complete cross-sections, e.g. bar stock and wire, the rolls (16, 17) of roll stands, which have three or more rolls, are fitted with clover-leaf grooves (18) which have projections (18a) corresponding to the number of rolls and indentations situated between them. The boundary surfaces (19) of the projections extend symmetrically to the planes (B) of division of the rolls and extend at a distance from the groove centre (M) which is equal to or slightly larger than the circumferential surfaces (20a) of the inlet cross-section (20) or of the blooming pass. By a substantial decrease in height taking place with a corresponding increase in length due to the geometry of the clover-leaf groove in the region of its indentations, an increase in length takes place in the projections of the clover-leaf groove practically by drawing along the cross-sectional parts not being under direct pressure, i.e. in the region of the projections (18a) the groove can remain underfilled. As a result, a spread-free rolling is made possible in order to implement the advantages of the single-pass oblique rolling process in a multi-pass forming and profiling of rolled stock. The row of grooves can also comprise circular grooves. <IMAGE>
