Abstract

In a hot strip rolling process, the strip (5) is subjected to thickness reduction between the end of a cooling line (2) and a coiler (4). An Independent claim is also included for a hot strip mill for carrying out the above process, including thickness reducing rolls (3') between the cooling line end and the coiler (4). Preferred Features: The thickness reducing rolls (3') comprise strip driving rolls and/or an additional roll stand ahead of the driving rolls.
