Abstract

In order to obtain a rolled material of advantageous structure and therefore improved mechanical properties in a merchant or intermediate mill, the finishing set of the merchant or intermediate mill and/or a finishing group formed by the last stands of the finishing set is preceded by at least one water-cooling zone. Appropriately, this water-cooling zone is followed by a compensating zone which allows an equalisation of the core and outside temperatures of the rolled material before it enters the finishing set or the last stands of this. <IMAGE>
