US 2020/0047230 A1 · COOLING OF ROLLED MATERIAL

Abstract

A cooling bar (1) for cooling rolled material (5) being moved in a transport direction (3) and in particular for reducing temperature differences in the temperature of the rolled material (5) transversely to the direction of transport (3). The cooling bar (1) has several full jet nozzles (11) by means of which a coolant beam of a coolant with an approximately constant jet diameter can be distributed to the rolling stock (5) in the direction of distribution (15). A cooling device has at least two cooling bars (1) of that type. The cooling bars extend transversely to a transport direction, one behind the other. Each cooling bar has a respective different pattern of jet nozzles and selection of applicable pattern of jet nozzles in their respective bars selectively cools the rolled material transversely to the transport direction.

Dependent claims

A cooling bar for cooling rolled material which is moved in a transport direction, the cooling bar including

a spray chamber which is fillable with a coolant;
a distribution chamber for intermediate storage of the coolant and which is connected to the spray chamber by at least one through opening for filling the spray chamber with coolant from the distribution chamber;
each through opening is arranged on an upper side of the distribution chamber and extends between the distribution chamber and the spray chamber;
multiple full jet nozzles which are suppliable with coolant from the spray chamber, each jet nozzle is configured to supply and output a coolant jet of a coolant to the rolled material in an output direction, and is configured so that the coolant jet has an almost constant jet diameter;
each full jet nozzle comprises a tubular nozzle body which includes an open end arranged in an upper region of the cooling bar inside the spray chamber for supplying coolant into the full jet nozzle;
wherein the open end is arranged above a height of the upper side of the distribution chamber.
