Abstract

A reversing two-high sectional rolling mill stand with multiple pass rolls whose bearing members are adjustably guided in windows of posts of the rolling mill stand. The rolling mill stand is arranged together with additional rolling mill stands of the same type adjacent to each other in series transversely to the rolling direction. The rolls can be connected to drive units or to drive transmission elements arranged between the rolls of adjacent rolling mill stands. Adjustable and fixable guide members for the rolled material are arranged on both sides of the rolling gaps for each of the rolls. The guide members are adapted for the section passes and are mounted jointly on support members which can be connected to the rolling stand. Connecting tops are hinged to the beams of the rolling mill stand and can be slid upwardly and pivoted outwardly for removing the roll. The bearing members of the rolls are placeable into a support frame which can be placed between the beams of the stands and can be moved out from between the beams. The support members of the guide members for the rolled material can be placed in the support frame.

Claims4

Dependent claims

A reversible roll stand, comprising:

a plurality of multi-caliber rolls comprising at least a top roll and a bottom roll:
bearing members partially surrounding said rolls;
posts having beams;
windows having tops formed by said beams, wherein said bearing members are adjustably guided in said windows;
connector caps on said beams carrying adjustment elements for the bearing members displaceable for disassembly or removal of the rolls;
a support frame, wherein the rolls with their bearing members are placed and wherein said support frame is insertable and removable through the tops of the windows;
carriers of rolling material guides, wherein said carriers are insertable into said support frame, wherein said support frame, further comprises a pair of U-shaped plates connected with each other in a plane-parallel manner by spacer members, said U-shaped plates defining an aperture and having recesses wherein said rolls with said bearing members projecting outwards on both sides are held in the recesses;
web region of the U-shaped plates, wherein said web region forms a support face for bottom sides of the bearing members of the bottom roll;
and
opposed pairs of cantilever projections formed in upper portions of each U-shaped plate, wherein said cantilever projections protrude into the aperture for engaging cooperating ledge portions formed in the bearing members of the top roll during roll changes.
