Abstract
A cooling device for cooling a hot, moving metal strip by means of laminar coolant jets consists of at least one water box (3) located across the direction of strip travel, into which at least one coolant supply line (4) leads and from which a plurality of coolant discharge lines (5) arranged at a distance from one another depart. In order to ensure that uniform flow conditions occur in the coolant jets during operation, particularly also during the starting and stopping phases of the cooling device, and to reliably prevent uncontrolled continued coolant flow, a shut-off device (6) is allocated to each coolant discharge line (5).
