Definitions

  • the present invention relates to a device for cooling rolling stock, preferably in a rolling train.
  • Apparatus and methods for cooling rolling stock in a rolling train are well known.
  • controlling and guiding the metal temperature is of paramount importance for a variety of reasons.
  • the rolling stock can be transferred after finish rolling through targeted temperature control in a variety of structural states, which may have, for example, ferritic, pearlitic, bainitic or martensitic components. This temperature control is done by cooling devices behind the finishing streets, which are known in different designs.
  • the rolling stock In cold rolling mills for steel or other metals, the rolling stock is heated by the introduced roll energy during forming. Again, certain harmful temperature ranges for the rolling stock must be avoided, such as in steel, the temperature range of Blausprödtechnik. Certain materials continue to tend to coarse grain formation even at elevated temperatures. Accordingly, also in cold rolling mills strip cooling systems are used.
  • the temperature of the rolling stock must also be controlled in order to prevent such inflammation.
  • spray cooling which direct a cooling medium by means of nozzles on the belt.
  • the cooling device for cooling hot strips shown.
  • cooling water is blasted directly onto the belt under high pressure.
  • the cooling device has on the one hand substantially parallel to the belt fixedly arranged Abzhouplatten and on the other hand on stationary dewatering rollers.
  • the stationary lower discharge plate placed below the belt prevents uncontrolled flow or dripping off of the cooling water into lower regions of the cooling device. It directs the dripping cooling water to a lower dewatering roll, by means of which also adhering to the underside of the tape cooling water is stripped by this.
  • the stationary upper dewatering roller the cooling water located above the belt is skimmed off from the upper side of the belt, and conveyed for targeted discharge to the upper discharge plate.
  • laminar coolings which direct a jet almost pressure-free on the rolling stock.
  • a cooling device is after DE 197 18 530 A1 especially for hot-rolled strip in direct current, in which the intensity of the cooling is controlled by relative adjustment of mutually independently adjustable parameters (cooling time, volume flow, pressure, etc.). In this case, a safety distance to the boiling point of the cooling medium is maintained to avoid unstable film evaporation.
  • cooling medium is passed in a jet to the sheet or strip or other rolling medium and there impinges with some kinetic energy. At the point of impact of the blasting on the rolling a high heat transfer occurs. However, the beam decays completely and the kinetic energy of the beam is removed. This then forms a chaotically flowing cooling medium, which then has a significantly lower cooling effect on the band.
  • the jet of cooling medium decays uncontrolled and distributes different directions.
  • the cooling medium then flows in the direction of the jet.
  • the cooling medium is entrained with the belt.
  • the presence of cooling medium outside of the cooling device is generally undesirable because a corresponding volume of cooling medium can slip from pulleys, contaminate the rolling hall itself, contaminate the belt, emit different emissions, such as odors and aerosols, interfere with gauges can, for example, optical and radiometric instruments and an adverse effect on the rolling to roll gap to adjust the tribologically correct conditions in the nip can have.
  • the known cooling devices are accordingly sealed to avoid the entry of cooling medium in other areas of the plant contact with rollers and seals or the like, such as from the DE 28 44 434 A1 disclosed.
  • the apparatus for cooling rolling stock preferably for cooling during cold rolling, has a nozzle for applying a cooling medium to the rolling stock.
  • a cooling chamber which is in fluid communication with the nozzle and extends parallel to the strip running plane, is provided for applying the cooling medium to the rolling stock, the device having an adjusting device for reversing the flow direction of the cooling medium in the cooling chamber by displacing an outer shell of the device, wherein the Case is displaceable from a first position to a second position, so that depending on the position of the outer shell, two feeders and two processes are connected to each other such that the flow direction of the cooling medium is changeable.
  • the surface on which the cooling medium acts can be significantly increased, since the cooling channel provides the possibility of providing a geometrically defined region with cooling medium.
  • Injection of the cooling medium after hitting the rolling stock is likewise avoided in the manner according to the invention.
  • the pressure level of the cooling medium by the targeted guidance of the cooling medium along the Rolled good can be reduced, whereby a corresponding energy savings can be achieved because the cooling medium must not be placed under such strong pressure.
  • the cooling chamber is formed between the rolling stock and a chamber roof.
  • the direct contact between the cooling fluid and the rolling stock is achieved and distance variations between the chamber roof and the rolling stock can be easily compensated by adjusting the volume flow.
  • the nozzle is designed such that the cooling medium can be conducted in a substantially uniform flow into the cooling chamber.
  • the cooling medium can be conducted in a substantially uniform flow into the cooling chamber.
  • the nozzle can be considered a slot nozzle, which has an equidistant gap across the width of the cooling chamber.
  • the transition from the nozzle into the cooling chamber is provided with a tear-off edge, which can be realized, for example, in the form of a height offset between the nozzle gap and the cooling chamber roof.
  • a tear-off edge which can be realized, for example, in the form of a height offset between the nozzle gap and the cooling chamber roof.
  • the cooling chamber is formed so that the cooling medium can flow through the cooling chamber in a substantially uniform flow.
  • the cross section of the cooling chamber in the strip running direction is substantially constant.
  • Such a uniform cooling would no longer be the case with the formation of vertebrae.
  • the cooling chamber extends counter to the strip running direction such that the cooling medium is guided counter to the strip running direction.
  • the cooling medium is first used at the coldest region of the rolling stock and then flows to warmer areas of the rolling stock, whereby an optimal heat transfer takes place in all areas.
  • the cooling chamber may have at least one cooling chamber roof extending parallel to the rolling stock and preferably at least one side wall extending perpendicularly to the rolling stock and in the direction of strip travel for laterally delimiting the cooling chamber. This allows the cooling chamber to build up in a simple manner.
  • a flow brake for example in the form of a spaced sealing strip or a similardeschengung, which prevents the unhindered outflow of fluid from the cooling chamber.
  • the device has in a preferred form at least one adjustable side wall, which is positioned at a defined distance to the bandwidth of the rolling stock to be cooled. This ensures optimal guidance of the flow in the cooling chamber and the formation of vortices is avoided.
  • a drain chamber for removing the cooling medium from the rolling stock. It is particularly preferred in this context if the discharge chamber is widened in relation to the cooling chamber in order to reduce the flow rate of the cooling medium in the discharge chamber compared with the flow rate of the cooling chamber.
  • the supply of cooling medium in the nozzle is adjustable, preferably via an adjustable pump unit, and the supply of the cooling medium depends on different parameters of the rolling stock, preferably depending on the temperature of the rolling stock, the material of the rolling stock, and / or Residual fluids determined on the rolling stock after passing through the device.
  • the cooling chamber can be moved away from the plane of the rolling stock.
  • At least one outflow device can be provided for removing excess cooling medium on the rolling stock outside the cooling chamber, preferably in the form of a blow-off device, an injection, a suction device, a transverse blower and / or a blower.
  • FIG. 1 schematically shows a rolling mill with multiple rolling stands 1, by means of which the rolling stock 2 is rolled thin. Cooling devices 3 for cooling the rolling stock 2 are shown schematically in front of the first stand, behind the last stand and between the stands.
  • FIG. 2 shows a further rolling train, in this case with a likewise schematically indicated reversing stand 1, in front of and behind which each cooling devices 3 are provided for cooling the rolling stock 2.
  • the cooling device 3 can be arranged at any point before, between or behind the respective rolling stands 1. Accordingly, there is freedom to arrange the cooling devices 3 so as to best serve the respective rolling case.
  • FIG. 3 schematically shows a cooling device 3, which is supplied via an inlet 30 with cooling medium.
  • the inlet 30 is provided with a diffuser such that the cooling medium 34 is uniformly introduced into a nozzle 32 surrounding the diffuser.
  • the cooling medium 34 is shaped into a uniform, accelerated flow with which it leaves the nozzle 32.
  • Adjoining the nozzle 32 is a cooling chamber 4, which extends substantially parallel to the plane 10 defined by the rolling stock 2, which is also referred to as the strip running plane, and which is suitable for applying the cooling medium 34 to the rolling stock 2.
  • the cooling medium 34 flows from the nozzle 32 accordingly further and comes into contact with the rolling stock 2 in accordance with threaded stock 2 threaded. Accordingly, a heat transfer from the rolling stock 2 to the cooling medium 34 takes place at least in the region of the cooling chamber 4.
  • FIG. 5 is described by the long and defined contact time of the cooling medium 34 with the rolling stock 2 - compared to a simple spraying of the rolling stock 2 - an efficient cooling of the rolling stock 2 instead.
  • the cooling chamber 4 consists essentially of a chamber roof 40, which preferably extends directly adjacent to the nozzle 32.
  • the chamber roof 40 is arranged opposite the upper surface 20 of the rolling stock 2 so that the flowing in the nozzle 32 cooling medium 34 is passed from the nozzle 32 into the cooling chamber 4, in which the cooling medium 34 then in a substantially eddy-free flow on the rolling stock 2 flows along.
  • the tape running direction W of the rolling stock 2 is indicated. It can be seen immediately that the cooling chamber 4 extends from the nozzle 32 counter to the strip running direction. In other words, the nozzle 32 is arranged in the tape running direction W behind the cooling chamber 4.
  • the cross section in the strip running direction W of the cooling chamber 4 is substantially constant, so that the flow velocity of the cooling medium 34 in the cooling chamber 4 is substantially constant and at the same time a substantially vortex-free flow can be formed.
  • the cooling medium 34 comes into contact with the rolling stock 2 in the region of the cooling chamber 4 in such a way that an efficient and uniform flow without vortex is present here.
  • the cooling medium 34 emerges with diffuse flow and can be absorbed in the usual way.

  • the velocity distribution of the flow within the cooling chamber 4 is shown.
  • the largely symmetrical velocity profile of the flow is shown without belt travel or without belt speed.

  • the nozzle 32 is designed to achieve a uniform flow velocity across the cooling chamber 4 across.
  • FIG. 5 shows in a comparison, the cooling device 3, as shown in the Figures 2 and 3 is shown, compared to a conventional spray device 3 '.
  • a substantially uniform flow is formed, which is passed through the cooling chamber 4 therethrough. Accordingly, in the region of the cooling chamber 4, a heat transfer, as shown schematically below this device, can be achieved. Accordingly, there is a constant heat transfer on the surface 20 of the rolling stock 2, as can be seen from the schematic diagram below.
  • FIG. 6 a preferred form of the cooling device 3 is shown schematically, in the transition from the nozzle 32 into the cooling chamber 4, a spoiler edge is recognizable.
  • This has the task of preventing adhesion of the fluid flow to the cooling chamber roof and thus to direct the fluid flow to the belt surface and to better fill the cooling chamber.
  • the spoiler edge has been realized in this example by a height offset between the nozzle gap and chamber roof in such a way that the distance of the chamber roof to the belt surface greater than the height H of the nozzle column relative to the belt surface.
  • FIG. 7 shows a further preferred embodiment of the cooling device, in which the width of the cooling chamber 4 is adapted to the width of the current strip material. This is done in the example shown by the displacement of the two side walls of the cooling chamber 4, which are oriented substantially parallel to the bandwidth.
  • the side walls are in FIG. 7 shown in phantom; their displacement is possible in the direction of the double arrows.
  • This adaptation of the channel width ensures optimal guidance of the flow along the rolling stock and the formation of vortices counteracted.
