Rolling stand for oblong metal products comprising a plurality of rolling rolls (11) each installed on a respective rotation shaft (12), between at least one rotation shaft (12) and the respective rolling roll (11). A coupling member (15) is provided and is configured to couple the rolling roll (11) and the rotation shaft (12) to each other. The coupling member (15) comprises a tubular body (16) interposed between the rolling roll (11) and the rotation shaft (12) and provided with a chamber (17) in which a deformer element (18) is inserted mobile.

A roll-holder cartridge for a three-tube rolling stand with means adapted to release a tube during rolling in case of emergency. The roll-holder cartridge (3) has on both side walls a substantially Y-shaped opening (10) laying with the foot at the vertical axis yoke support so as to be able to pull out the roll-holder cartridge according to a direction coinciding with the horizontal axis of the vertical axis yoke while leaving the support hanging from the fixed structure (13) of the rolling stand. In case of normal maintenance operation, the cartridge (3) is pulled out sideways from the structure of the rolling mill with the yoke support of the vertical axis roll anchored to the cartridge itself, like the other supports of the rolls.

A split ring for use in assembling a bearing retainer onto a roll. The split ring helps keep a mounting jack in compression with the bearing retainer as the mounting jack compresses the bearing retainer onto the roll. In some embodiments, the split ring includes a plurality of apertures that are each configured to receive a drive mechanism that helps collapse the mounting jack to allow for removal of the split ring and the mounting jack once the bearing retainer is assembled onto the roll.

A hot-rolling stand (10) for a hot-rolling mill comprises an adjusting device (12), which is intended for receiving a pair of work rolls (17) and for positioning work rolls (18, 19; 20, 21) of the pair of work rolls (17) in relation to one another to define a roll gap. In order to create a hot-rolling stand (10) that can be adapted as flexibly as possible, the adjusting device (12) is designed to interchangeably accommodate, in the pair of work rolls (17), different roll diameter ranges by means of mutually complementary work rolls (18, 19; 20, 21).

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), which comprises at least four contact surfaces which are arranged on an outside (12) of the stand housing (10) and which, viewed along the rolling axis (19), are in parallel therewith. Of the contact surfaces, two form non-adjacent, mutually parallel contact surfaces, and the two others form adjacent contact surfaces. In this case, the adjacent contact surfaces are at an angle of 120 to one another, and each thereof is at an angle of 120 to one of the parallel contact surfaces. The two parallel contact surfaces and/or the adjacent contact surfaces are designed to receive sliding rails (40.2, 40.3, 40.4, 40.5) for inserting the stand housing (10) into a stand base.
