Abstract
In a process for cooling hot rolled metal plates (16) and strips, especially such of aluminium or an aluminium alloy, a hot rolled strip (12) is cut to plates (16) immediately after it emerges from a rolling mill (10). Immediately after the cutting to length, the plates (16) pass through a cooling station (20) where they are jetted directly with water from flat stream nozzles (52). The water stream (W) emerging from the flat stream nozzles (52) form essentially a plane (E) which is directed at the plate surface (32). Immediately after it leaves the flat stream nozzle (52), the water stream (W) is periodically deflected by means of streams (A, B) of air or water in such a manner that the water stream (W) striking the plate surface (32) performs a wiping action.
