摘要： A descaling device for slabs or strips in hot rolling mills includes nozzles fed by a pressurized water piston pump for directing water jets against the slab or strip for removing scale adhering to the surface of the slab or strip. At least one additional pressurized water piston pump is provided, wherein the piston pumps are connected in parallel and the pumps can be switched on and off separately. A second row of nozzles may be arranged in front of the nozzles at a distance which ensures that the water jets do not influence each other. The water pressure of the water supplied to the second row of nozzles is preferably lower than the water pressure supplied to the first row of nozzles.

摘要： A hydrostatic transmission with a closed hydraulic circuit includes a consumer which is connected through work lines to a reversible hydraulic pump and is pressurized on both sides by an external pressure source. The hydraulic circuit includes a first continuous rinsing and feeding circuit which depends on the leakage flow of the hydraulic pump and possibly a second discontinuous rinsing circuit separate from the first circuit and connected to the external pressure source. The hydrostatic transmission further includes an adjustable regulating device which determines through a valve the adjustment of the hydraulic pump. The regulating device, which may be arranged outside of the immediate vicinity of the hydrostatic transmission, interacts with a control device which is directly assigned to the hydrostatic transmission and includes a valve constructed as a servo valve, wherein, for adjusting the arrangement, the servo valve can be switched to manual control. A manually operable lock valve is provided between the servo valve and the hydraulic pump adjustment. The throttles used for pressurization are adjustable as well as lockable and the work lines are equipped with pick-ups for the actual pressure value.
