Abstract: In a roll stand, more particularly a cluster roll stand, having guard plates (15, 21) which are disposed opposite one another in pairs above and below the strip (B) processed in the roll stand in the run-in zone (E) and run-out zone (A) of the roll stand and which extend into the roll stand substantially as far as the stand working rolls (1, 8) supported by supporting rolls (2-6a, 9-13a) and/or undriven supporting rollers, the lower guard plates (21) each being connected to the lower member (14) of the stand pivotably around a pivot (22) disposed axis-parallel with the working rolls (1, 8), the objective was to improve the protective effect of the guard plates (15, 21), while at the same time reducing expenditure on the lifting means required to lift the upper working roll (1).

Abstract: A device for removing liquid from the surface of a moving strip (B), more particularly a rolled strip on a roll stand, by means of a gas, more particularly air, blown on to the moving strip (B), is characterized according to the invention in that disposed transversely of the direction (L) in which the strip runs is a slot nozzle (3) which is directed at the strip surface at an angle (.beta.) of 45.degree. to 90.degree. of its jet oppositely to the direction (L) in which the strip runs, the ratio between the distance (h) of the slot nozzle (3) from the moving strip (B) and the width (s) of the slot is in the range h/s=2 to h/s=10, so that the velocity of emergence of the gas jet blown by the slot nozzle (3) on to the strip (B) is in the range of 0.3<Mach<2, and a suctional removal gap (4) is disposed above the strip (B) at a distance of 5 to 25 nozzle distances (h) in the direction (L) in which the strip (B) runs upstream of the line of impingement of the gas jet emerging from the slot nozzle (3).

Abstract: The invention relates to a device for cooling a laminar material, more particularly a metal strip 2, by liquid nozzles 11a, 11b, 12a, 12b disposed on both sides. The liquid nozzles 11a, 11b, 12a, 12b take the form of full-jet nozzles and so act upon the surface of the material 2 to be cooled by rebounding jets that zones of shooting flow SS are formed around the point of impingement of the individual rebounding jets.

Abstract: The invention relates to a cluster mill having four columns 5, 6 connecting the lower part 1 and the upper part 2 for the sets of rolls 3, 4. Associated with each column 5, 6 is a lifting device 11, 12 enabling the lower part 1 and the upper part 2 to be moved wide apart. A hydraulic roll screw-down system independent thereof has an adjustable piston 16 which can be attached to the column 5, 6 and between which and the bottom of its cylinder casing 17 borne by the upper part 2 the necessary roll force can be built up. Due to the adjustable piston 16, for any required roll gap the cylinder space in which the pressure for the roll force is built up has a low height.
