ABSTRACT:
A clamshell-type rolling mill stand is provided with separate top and bottom housing boxes each carrying a cantilevered work roll. The rolls are in the form of roll rings mounted on the front extension of a main shaft carried in a main load bearing in the front wall and a reaction load bearing in the back wall of the housing box. Each housing box contains a drive gear integral with the main shaft which is driven by a plurality of planetary pinions. Each pinion shaft projects through the box back wall where it is coupled to a drive motor, usually hydraulic, fixed to a bracket also mounted on the box to move with it. A fixed pass line is maintained by means of a symmetrical adjustment of the top and bottom housing boxes on either side of the pass line. This is accomplished by eccentric bushings on a shaft through each box, the shafts being rotatable but held at a constant distance from each other by spacer-supports which are free to move in the rolling direction but are restrained from movement in the pass line direction facilitating guide positioning and tracking of the stock during rolling.
