A vacuum roll mill stand comprises a housing closed at opposite sides with covers and having its interior brought in communication with a vacuum pumping means to thereby form a chamber adapted to accommodate chocks carrying workrolls geared through the intermediary of spindles to a drive. The chocks together with the workrolls are secured on one of the housing covers thereby forming a frame, the housing being annular in shape and arranged so as to have its geometrical axis coincident with the axis of rolling; the housing also being fitted with through openings adapted to receive the spindles together with vacuum seals.

Vacuum roll mill stand

A mill stand has a roll housing which mounts chocks provided with cantilevered axles carrying workrolls with at least one axle being connected with a spindle geared to a drive. The spindle of at least one workroll is positioned in direct proximity with the axle which carries this workroll, on the side of its free end. Such mill stand construction makes it possible to effect rolling of difficult-to-form metals and alloys.

Mill stand

A continuous mill has a plurality of passes arranged in series and formed by work rolls which are mounted on shafts secured to common chocks accommodated in housings. The chocks provided in the mill are equal in number to the workrolls forming a pass. Each of the chocks has two sides converging at an angle, and the shafts carrying the workrolls are cantilevered to each of said sides. The shafts secured to one side are offset relative to the shafts secured to another side so that the adjacent passes are spaced in closest possible proximity with one another; the angle between the sides of each chocks being equal to the divergence angle of the adjacent passes.

Continuous mill

A roll mill stand has a supporting frame which mounts two housings with at least three work rolls being arranged therebetween, the geometric center lines of the rolls being located in a single plane and set one with respect to another to form a pass. The work rolls are mounted each in a respective shell, the latter being hinged upon one of the housings by a pivot secured in the housing parallel to the work roll and connected to the other housing by a screw-down mechanism intended to adjust the radial gap between the work rolls. At least one of the shells is supported by the respective pivot connecting the shell to the housing, the gap between the work rolls being adjustable transversally with respect to the axis of rolling.

Roll mill stand

A roll mill stand comprises a housing which mounts chocks having secured therein journals carrying work rolls forming a pass, at least one of said work rolls being coupled by means of a splined joint with one end of a spindle, the other end of said spindle being connected by a splined joint to a pinion geared to a drive means. The roll mill stand is provided with an arrangement for axial displacement of the spindle, comprising a motion screw mounted coaxially with the spindle and coupled with its other end, the motion screw carrying a nut with a disk affixed to the end face thereof, the nut being mounted on a hub coupled with the spindle shaft for rotation with respect to said nut, the roll mill stand being additionally provided with a braking mechanism placed on the stationary part of the roll mill stand and cooperating with the disk of said nut, as said nut is being slowed down to disengage the spindle from the work roll.
