Abstract (en)
[origin: US4298188A] The machine for cooling metal sheets has a lower frame and an upper frame, sets of sheet driving and guiding rolls rotatively mounted in the frames. These frames define an enclosure which surrounds the rolls and in which enclosure a cooling fluid circulates. A system of fluid discharge conduits is connected to the upper frames and a system of fluid discharge conduits is connected to the lower frame. These discharge conduits are disposed in the vicinity of input and output ends of the machine. A cooling fluid recovery tank is provided. At least the discharge conduits connected to the upper frame and located in the vicinity of the input and output ends of the machine are connected to the cooling fluid recovery tank with interposition of a siphon. A priming device is combined with the siphon for creating a depression in the siphon. There may also be associated with the cooling fluid discharge system of the lower frame, for instance on at least one discharge conduit connected to the lower frame, apparatus such as a valve, adapted to regulate the flow in the respective conduit, for regulating the pressure drop in the machine.
Abstract (fr)
Le but de ce perfectionnement consiste à diminuer les fuites de liquide aux extrémitiés d'entrée et de sortie de la machine. Ce résultat est obtenu en reliant les conduits supérieurs d'évacuation (22) au bac de récupération R au moyen d'un siphon (23-26) muni d'un dispositif d'amorçage (27). Par ailleurs des moyens (21) sont prévus pour faire varier la perte de charge dans la machine.
