A cooling device for cooling a hot, moving metal strip by means of laminar coolant jets consists of at least one water box (,) located across the direction of strip travel, into which at least one coolant supply line (,) leads and from which a plurality of coolant discharge lines (,) 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 (,) is allocated to each coolant discharge line (,).

Cooling device for cooling a hot, moving metal strip

Apparatus and method for descaling a workpiece with a liquid jet

There is disclosed an arrangement and for alternatively producing a hot-rolled strip, a hot-formed pre-strip or an unformed slab, of steel by the continuous casting method. In order to obtain a high product quality for strips as thin as possible and to ensure a high operational flexibility, the following characteristic features are realized individually or in combination:

Process for the production of a strip, a pre-strip or a slab

There is disclosed a rolling arrangement including a rolling stand and a preceding descaling means. In order to obtain a perfect surface quality while maintaining a high energy content of the rolling stock the descaling means is arranged immediately in front of the rolls of the rolling stand and is formed by a rotor descaling means. The liquid jets emerging from the rotor descaling means and impinging on the rolling stock are directed opposite to the rolling direction. The liquid impinging on the point of impact of the liquid jet on the surface of the rolling stock, after impingement has a flow resultant which--projected on the rolling direction--has a component opposite to the rolling direction.
