Distributor tube for cooling metal strips

Abstract

The invention refers to a distributor tube (400) for cooling metal or similar products, in particular steel strips, comprising along the longitudinal extension of said distributor tube (400), a plurality of outlet openings (406) through which a cooling fluid can be ejected; an inlet (402) and a closure (404) of said tube at its ends; a connection for connecting a source of cooling fluid and feeding said distributor tube (400) with said fluid. At least on the inlet side (402) there is a zone of change in the diameter of the tube, which varies from a sector with a smaller diameter, followed in the direction of flow by a sector with a larger diameter. Upstream of said plurality of outlet openings (406) there is an orifice (414) in the area of the flow section. Further described are a corresponding hot-rolling plant and a use of the distributor tube.
