In the present invention, a pair of left and right vertical rolls disposed coaxially in a vertical roll choke disposed on an axis center that intersects the axial center of the pair of upper and horizontal rolls, and the vertical roll chocks 3, 3 are to be rolled. A universal rolling mill is disposed in the housings 1 and 1 so as to be able to slide freely along the rolling direction of the material. Each of the assemblies consists of a cylindrical nut and a screw disposed on one side of the vertical roll choke 3, 3 along the rolling direction in the space between the housing 1, 1 and the vertical roll choke 3, 3. Using this structure, it is possible to use conventional vertical roll chokes, to ensure sufficient mechanical strength against reaction forces applied to the vertical rolls during rolling, and to significantly shorten the time required to change rolls.

Chockless roll support system

A chockless work roll support and positioning apparatus and method comprises a pair of brackets for each end of each work roll and having a pair of work roll support rollers rotatably mounted on each bracket. Each bracket is connected to at least one actuator means, such as a hydraulic piston/cylinder assembly, preferably one actuator means for each support roller. The actuator means are actuated through a servovalve, by position or pressure signals to position the support rollers at desired positions and to exert a desired pressure between the respective support rollers and the corresponding work rolls. By such signal control, the work rolls may be balanced, bent in the upstream or downstream horizontal direction, upwardly or downwardly, or may be placed in offset or cross-rolling position.
