Abstract: A universal rolling mill stand includes a drive side roll mount, an operator's side roll mount extending parallel to the drive side roll mount and adapted to move away therefrom, and an alternate frame, in which horizontal and vertical rolls are mounted and which is movable together with the operator's side roll mount.

Abstract: A horizontal/vertical roll stand with a pair of work rolls which can be exchangeably mounted with chocks and adjusting spindles in the stand includes a housing which is formed by four posts which extend from the corners of a common base plate, wherein the posts have an essentially rectangular cross-section. A cube-shaped receiving space which is open toward the top and at the sides for a cassette-type roll mounting unit is defined by the base plate and the four posts. During the exchange of the rolls, the roll mounting unit can be pulled out as a structural unit from the receiving space of the stand. Pairs of the posts form guides therebetween. A total of four support plates with a center support member each for four adjusting spindles are releasably fastened to the guides. The adjusting spindles have adjusting nuts on right/left thread portions, wherein pairs of adjusting nuts engage with cylindrically shaped projections into chocks of the rolls and adjust the rolls.

Abstract: A roll stand for a pair of work rolls includes a housing with two side walls arranged on a common base plate. A cube-shaped receiving space which is open toward the top and toward two sides and is provided with guide surfaces for an insertable roll cassette is formed between the side walls. The insertable roll cassette of the roll stand includes two side plates which extend parallel to each other and are spaced at a distance from each other. The outer sides of the side plates are guided by the guide surfaces of the side walls. The side plates form guide means for two pairs of chocks which receive the work rolls with the bearings of the rolls. A pair each of interacting chocks are connected by means of adjusting spindles which absorb rolling forces, wherein the distance between chocks is adjustable so as to produce pre-adjustable passes. The adjusting spindles include adjusting collars and the side plates have adjusting pieces which are compatible with the adjusting collars.

Abstract: A combined, continuously operating high-speed light-section and wire mill composed predominantly of so-called cantilever stands or CL stands with overhung-mounted collars. In the roughing train and in the intermediate train and/or in the finishing train, some rolling mill stands with a modular unti with double-mounted collars are arranged. A CL modular unit of the CL stands with overhung-mounted collars can be exchanged as required against a modular unit with double-mounted collars. The second bearing of the modular unit is arranged in a box stirrup which can be coupled to the gear box of the CL stand. The collar can be assembled and disassembled with an automatically actuated, preferably hydraulically acting quick fixing device which includes piston-cylinder units for clamping and releasing the collar on the shaft in axial and in radial direction. The modular unit is a roll box of sandwich construction with box plates which can be separated from each other.
