HOT-ROLLING STAND FOR A HOT-ROLLING MILL AND FOR PRODUCING A FLAT METAL PRODUCT, HOT-ROLLING MILL AND METHOD FOR OPERATING A HOT-ROLLING MILL
A hot-rolling stand (10) for a hot-rolling mill comprises an adjusting device (12), which is intended for receiving a pair of work rolls (17) and for positioning work rolls (18, 19; 20, 21) of the pair of work rolls (17) in relation to one another to define a roll gap. In order to create a hot-rolling stand (10) that can be adapted as flexibly as possible, the adjusting device (12) is designed to interchangeably accommodate, in the pair of work rolls (17), different roll diameter ranges by means of mutually complementary work rolls (18, 19; 20, 21).

Method and device for providing inserts for support and/or work rolls of a roll stand
A method relates to providing shims for backup and/or work rolls of a rolling mill stand. The shims are required when changing over rolls. The method comprises the steps of: a) assembling at least one shim, preferably at least two or three shims, into an shim pack at a first location remote from the rolling mill stand; b) transferring the shim pack into a carrier element at the first location; c) transporting the carrier element together with the shim pack from the first location to the location near the rolling mill stand; d) removing the shim pack from the carrier element at the location near the rolling mill stand; e) using the shims when changing over rolls.
