摘要:
A rolling mill, especially an inclined roll or Diescher roll mill. Its stand is formed by a pair of portal frames on a cast plate on a foundation spaced apart by cassettes holding the upper and lower roll units and tie rods securing the portal frames against one another and the cassettes. The tie rods are spaced apart vertically or horizontally on the portal frames.

A roll head for a planetary crossrolling mill in which the roll shaft bearing the tapered roll is mounted at one end close to the tapered roll in a radial bearing and an axial bearing while the other end rests with teeth in a rotationally engaged but axially movable manner in a hollow shaft of a bevel wheel driving the roll shaft. To obtain a compact structure with arrangement of the components on paths of revolution with small radii, the support ring of the axial bearing is provided with two sets of facial teeth pointing in opposite directions and can be coupled alternately with one of two coupling rings, wherein one coupling ring with the support ring can be connected in a rotationally engaged manner for its axial adjustment with the roll shaft while the other coupling ring with the support ring for securing its position can be connected to the thrust collar of the axial bearing which, in turn, rests in a rotationally enaged but axially movable manner in the roll head housing, and the radial bearing arranged before the axial bearing accommodates the axial adjustment of the roll by a change in position between internal and external bearing rings or in its seat by changing position of the external ring in the roll head housing.

A skew rolling mill is equipped with a plurality of skew or inclined rollers each of which is constructed of a number of roller segments (1', 2) which are interconnected in a form-locking, force transmitting manner. These roller segments are so related to one another that different roller segments may be assembled to form a plurality of different skew rollers which differ from one another with regard to their calibration and purpose. Thus, different roller segments may have different structural features and they may be made of different materials. Such variability obviates the need for keeping complete sets of skew rollers in stock for each size or calibration.

A skew rolling mill is provided with only two working rollers offset from each other by 180.degree.. Restraining elements are provided between the rollers to prevent lateral bending of the stock being rolled.
