Abstract: Processes for continuous production of a thin metal strip, in particular a steel hot strip, directly from a metal melt and with a strip cast thickness of <10 mm by the roll-casting process. The cast metal strip is fed for in-line thickness reduction, and then to a storage device. To achieve a high-quality, hot-rolled metal strip with flatness tolerances comparable to those which can currently be achieved in the production of hot-rolled metal strip from continuous-cast thin slabs or slabs, at cast thicknesses of between 40 and 300 mm, in a continuous production process starting directly from metal melt. With the low strip cast thickness, a flatness measurement is performed on the moving metal strip, and the measurement results of this flatness measurement are used to influence the flatness of the metal strip in a targeted way.

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).

Abstract: A workpiece is moved past a rotor descaling device, which intermittently sprays the workpiece with at least one liquid jet formed intermittently in dependence on angular positions of a rotor rotating on a rotational axis intersecting the surface (23) of the workpiece (22).
