Abstract: A rolling stand comprising supporting shaft pairs 3, 4, in which these supporting shafts are supported at two sides and so as to be adjustable in two parallel roll housings 1, 2. At one side, rolling rings 15 can be slipped on the supporting shaft pairs 3, 4, while the other side can be coupled with drive elements 16. The roll housing 2 remote of these drive elements 16 can be moved away from the other roll housing 1 in the direction of the roll axes together with the bearings which are pulled off the supporting shaft pair 3, 4. The supporting shaft pair 3, 4 can be secured and fixed in the other roll housing 1 in the resulting cantilevering position which is supported on one side.

Abstract: To avoid impacts on the first pass of the rolled product through a universal rolling mill the vertical rolls of the rolling mill can be provided with their own integral drive according to our invention. In an electrical drive for a vertical roll the vertical roll is the rotor of an electric motor while the stator is a circular collar on a nonrotatable supporting axle for the vertical roll. In a hydraulic drive for a vertical roll a hydraulic motor is either located in a housing side extension of the structural member supporting the vertical roll to drive it from the outside by spur wheel gearing or by a frictional drive or the hydraulic motor is mounted in the nonrotating supporting axle of the vertical roll and engages on an inner cogged drive ring on the vertical roll from the inside by spur gearing positioned on a transverse plane.

Abstract: A pair of upper crossheads for a universal rolling mill is engaged with nut assemblies on extended ends of a pair of screwdown spindles. Each crosshead can be swung about a nut assembly on one of the screwdown spindles while disengaged from a nut assembly on the other screwdown spindle for pivotal movement of the crosshead to one side of the housing frame. The nut assemblies for the ends of the crossheads, which remain engaged with the screwdown spindles, have threads that raise the crossheads during pivotal movement. Pedestal supports on projecting wing portions of the frame carry the pivoted parts of the crossheads. During operation of the universal rolling mill, the upper crossheads are held in their operative position by a clamp engaged with a crosstie that extends between two nut assemblies that can be exposed.

Abstract: A universal rolling mill stand with adjustable sets of horizontal rolls and vertical rolls guided in window-type recesses of the roll housings. Each roll housing is formed by a pair of housing posts with cross-members connected by means of transverse supports. The bearing chocks of the set of horizontal rolls are vertically movable between the housing posts of the respective pair of housing posts and the bearing chocks of the set of vertical rolls are moved horizontally between outwardly cantilevering attachments of the pairs of housing posts. The upper cross-members connecting the pairs of housing posts can be raised and swung horizontally. A frame-type cage having plate-like wall members is connectible to lifting devices. The outer surfaces of the wall members of the cage are guided on guide surfaces of the housing posts of pairs of housing posts which face each other. The cage is vertically and horizontally movable with the mill stand and can be installed and removed from the rolling mill stand. The inner surfaces of the wall members of the cage form guide surfaces for adjustment movements of the bearing chucks of one or more of the rolls. The bearing chocks are supported by the cage and/or can be coupled to each other so that one is suspended from the other.

Abstract: A roll assembly for a rolling-mill stand has a pair of axis-defining, coaxial, and axially spaced journals, respective roll supports carried in the journals and rotatable therein about the axis, and a roll ring engaged between the supports. The roll supports are each formed with a pair of radially spaced and separate annular surfaces both centered on the axis and the surfaces of one support are directed at least generally axially toward the other roll support. At least one of the surfaces of each pair is substantially frustoconical and forms with the axis a different angle from the other of the surfaces of the pair. One of the supports is formed at the axis with an axially extending passage and the roll ring is formed with generally axially oppositely directed pairs of annular surfaces respectively complementary to and flatly engaging the annular surfaces of the roll supports. An extension stem axially fixed to the other of the supports extends with radial play through the passage and is provided with a nut or the like bearing on the one element, normally the service-side element, for pulling the two support elements axially toward each other and thereby axially compressing the roll ring between the annular surfaces of the roll supports.
