Guide device for rolling long metal products, comprising at least a pair of guide rolls coplanar with each other and rotatable round axes of rotation inclined with respect to a rolling axis, a support body on which the guide rolls are mounted and configured to keep the guide rolls constantly in contact with the long metal products, and a support structure configured to support the support body and to which the latter is attached. At least the support structure is made of one or more non-ferrous metal materials with a specific weight less than half the average weight of steel and with heat conductivity equal to or greater than double the average heat conductivity of steel.

Apparatus to guide a metal product, the apparatus includes a support body (11). A plurality of support arms (12) are associated with the support body (11). A plurality of guide rolls (13) are installed rotating in an idle manner on the support arms (12) and define between them a roller guide gap (14) for the metal product. Adjustment devices (24) associated with the support arms (12) and adjust, independently from each other, the position of each of the guide rolls (13. Detection devices (19) detect the stresses induced by the metal product on the guide rolls (13).

Torsion guide (10) comprising a support body (11) with which there are associated at least two torsion rollers (12, 13) rotatable around respective parallel rotation axes (T1, T2), distanced with respect to each other at least in a direction of adjustment (B) perpendicular to said rotation axes (T1, T2) and disposed on respective support elements (17, 18).

A method for manufacturing a guide roller for hot wire rolling includes the steps of providing a guide roller made of an Al alloy, the guide roller including a wire guiding surface, and applying a coating onto at least a part of the wire guiding surface by a metallic wire Direct Energy Deposition (DED) operation and/or a metallic powder DED operation.

A guide roller configured to guide a wire to or from a work roller in a wire rolling line includes a rolling-element bearing having a rotatable outer ring, a fixed inner ring, and rolling elements between the outer ring and the inner ring. The outer ring has a profile configured to guide the wire on a radially outer surface thereof. The guide roller is configured as a double row preloaded rolling-element bearing and is installable as a finished component on a fixed shaft of the wire rolling line without adjusting the preload.

The present application relates to a stand (1) for rolling metal rods, wires, or pipes, along a rolling axis (19). The stand (1) comprises three rollers (20.1, 20.2, 20.3) which are located on one roller shaft in each case and surround the rolling axis (19) in a star-shaped manner, and which together form a caliber (21), a stand housing (10) having an outside (12) which, viewed along the rolling axis (19), comprises at least six side surfaces (14.1, 14.2, 14.3, 14.4, 14.5, 14.6) that are arranged so as to be offset about the rolling axis (19), about a 60 rotation in each case, and two end faces (13, 15) which are opposite one another, wherein the side surfaces (14.1-14.6) form a regular hexagon, at least in an imagine extension, and a roller guide (60) which is attached to one of the end faces (13, 15) of the stand housing (10) and comprises a universal shaft (62), wherein the universal shaft (62) comprises a roller adjustment connector (64) via which a central adjustment of the roller guide (60) is possible and which is attached on the stand housing (10) in one corner (16.1, 16.2, 16.3, 16.4, 16.5, 16.6) of the hexagon.

The present application relates to a stand housing (10) for a stand (1) for rolling metal rods, wires or pipes along a rolling axis (19), wherein the stand housing (10) has an outside (12) which, viewed along the rolling axis (19), comprises at least six side surfaces (14.1-14.6) that are arranged so as to be offset about the rolling axis (19) about a 60 rotation in each case, and two end faces (13, 15) that are opposite one another, wherein the side surfaces (14.1-14.6) form a regular hexagon, at least in an imaginary extension, and at least one pair of coupling clamping regions (50.1, 50.2, 50.6) which is arranged in the region of a corner (16.1-16.6) of the hexagon, wherein each of the coupling clamping regions (50.1, 50.2, 50.6) of the pair is designed to receive a coupling (64) for a shaft (62) of a roller guide (60) for central adjustment of the roller guide (60). In this case, a coupling clamping region (50.1, 50.2, 50.6) of the pair is arranged on one of the end faces (13, 15) of the stand housing (10), and the other coupling clamping region (50.1, 50.2, 50.6) of the pair is arranged on the other of the end faces (15, 13) of the stand housing (10).

The present application relates to a stand base (10) for two or more stands (14) of a rolling mill arranged one behind the other in a rolling direction (W) of a material to be rolled, the stand base (10) comprising two or more receiving modules (12) arranged one behind the other, which are fastened to a common lower base frame (32) and a common upper cover frame (34).

Torsion guide (10) comprising a support body (11) with which there are associated at least two torsion rollers (12, 13) rotatable around respective parallel rotation axes (T1, T2), distanced with respect to each other at least in a direction of adjustment (B) perpendicular to said rotation axes (T1, T2) and disposed on respective support elements (17, 18).
