Abstract
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).
