Definitions

  • the present invention is directed to a method of and a device for dynamically supplying a cooling device for cooling a metal strip or other rolled stock with coolant.
  • the cooling device can include, in particular one or several spray bars.
  • State-of-the art discloses a number of systems for providing cooling water from a deep tank for a laminar or pressure cooling in hot rolling mill trains.
  • a substantial amount of cooling water is needed for a sufficiently defined and rapid cooling of a finished strip in accordance with the requirement to the finished product.
  • the necessary amount of water often varies in a range from several hundred m 3 /hr to even several thousand m 3 /hr. This extraordinarily large amount of water is fed, e.g., from a deep tank through valves of a throttled conduit system to spray bars.
  • FIG. 1 Such a system according to the state-of-the art is shown, e.g., in FIG. 1 .
  • Water which is stored in a deep tank/storage 4 is fed to a central distributor 6 via conduit 2 . From the common distributor 6 , water is fed by further conduits to separate spray bars 1 .
  • this known device has certain drawbacks. For contemporary alloyed metals and steels, a large cooling rate should be adjusted and controlled as precisely as possible. However, a very large amount of water which is used makes this very difficult.
  • switch-on and switch-off processes cannot be executed sufficiently quick, using the available approach that includes the use, primarily, of control valves, wherein the cooling switch-on process often requires more than 10 sec. for achieving the desired cooling rate. Because the rolled stock is displaced, in many cases, through the installation with a speed of several meters per second, a large strip length is not cooled with a desired cooling rate, which results in loss of quality of this strip section.
  • a further drawback consists in that during the cooling switch-on process, large forces act on conduit systems and/or cooling installations.
  • the danger of a rapid switch-on process of the cooling water (coolant) supply consists in that the strong pressure surges damage the cooling system. Such pressure peaks can even result in the breakdown of the cooling installation and, thus, of the entire rolling mill train.
  • the object of the invention is to provide an improved coolant supply which, in particular, would prevent pressure surges during the switch-on process or at least noticeably reduce them. Further object of the invention consists in achieving a more rapid cooling rate than the existing cooling rates in order to supply the coolant in most optimal manner to the rolled strip.
  • the object of the invention is achieved by features of a method of dynamically supplying coolant to a cooling device, in particular, to at least one spray bar for cooling a metal strip or a similar rolled stock with the coolant according to claim 1 .
  • the method comprises at least the steps of providing a pre-accelerated or flowing coolant flow, wherein the coolant flow by-passes the cooling device and is delivered to a return line, and monitoring presence and/or temperature of the to-be-cooled metal strip or the similar rolled stock.
  • the pre-accelerated coolant flow is diverted to the cooling device dependent on the presence and/or predetermined temperature of the metal strip or the similar rolled stock, so that the coolant flow instead of by-passing the cooling device and being delivered to the return line, is fed, being already pre-accelerated, to the cooling device for cooling the metal strip or the similar rolled stock.
  • the pressure surges acting on the installation components can be eliminated or noticeably reduced. Further, the cooling reaction time is noticeably improved.
  • the diversion process can be carried more rapidly than the process of acceleration of the remote amount of water.
  • the desired cooling rate can be achieved or adjusted more rapidly and more precisely. Overall, the adjustability of the used volume flow is, thus, improved.
  • the pressure loss of the coolant stream at by-pass of the cooling device and the pressure loss of the coolant stream at feeding of the coolant stream to the cooling device deviate from each other by less than 50%, preferably by less than 20%, or even by less than 10%.
  • both values are essentially the same.
  • pressure surges, at the deviation of the already accelerated coolant stream toward the cooling device are prevented.
  • the flow resistance to the coolant flow during deviation or feeding to the cooling device is essentially the same or differs less, as indicated above.
  • the deviation takes place, preferably, in less than 5 sec. or even in less than in 1.5 sec.
  • the inventive method is particularly advantageous at such a relatively small switching time.
  • the deviation of the coolant stream takes place at less than 5 m, preferably at less than 1 m upstream of the cooling device (so that the path of the coolant stream between the deviation site and the outlets of the device for cooling the strip is kept as small as possible).
  • a to-be-deviated volume flow of the coolant or the coolant flow amounts to more than 150 m 3 /hr and, preferably, to more than 400 m 3 /hr. Especially in view of such large volume flows, the present invention is particularly advantageous.
  • the invention is likewise directed to a device for cooling a metal strip, in particularly for carrying out the method according to one of the preceding claims.
  • the device comprises a cooling device for cooling a metal strip or a similar rolled stock and having at least one spray bar with coolant outlets for applying the coolant to the metal strip.
  • the devices further includes conduit means for conducting a coolant flow from a coolant source to the spray bars, and by-pass means for conducting the coolant flow from the conduit means to a return line.
  • switchable deflection means formed for switchingly conducting the coolant flow through the conduit means to the spray bars or for deviating the coolant flow from the conduit means into the by-pass means.
  • the cooling device has at least one valve for controlling the volume flow of the coolant flow that flows through the conduit means, wherein the deflection means is located downstream of the control valve.
  • the switchable deflection means comprises either at least one switchable valve for conducting the coolant flow to the spray bars or to the by-pass means.
  • the conduit means comprises a pump for increasing an available, from the source, coolant volume flow. With such a pump, an even stronger pre-accelerated volume flow can be made available.
  • the water pressure can, e.g., be provided by a water tower.
  • a plurality of spray bars preferably maximum ten spray bars are assembled in a first cooling group, wherein the first conduit means feeds the coolant to the first cooling group, and at most three spray bars of the first cooling group are provided with switchable deflection means for conducting the coolant flow from the first conduit means in the return line, so that cooling flow from at most three spray bars of the first cooling group is deviated into the by-pass means or the return line independent from the remaining spray bars of the first cooling group.
  • a plurality of further spray bars preferably maximum ten spray bars are assembled in a second cooling group and the second conduit means feeds the coolant to the second cooling group, and at most three spray bars of the second cooling group are provided with switchable deflection means for conducting the coolant flow from the second conduit means in the return line, so that cooling flow from at most three spray bars of the second cooling group is deviated into the by-pass means or the return line independent from the remaining spray bars of the second cooling group.
  • the volume flow to each separate cooling group is increased by using a separate pump.
  • the device comprises a plurality of spray bars, and each spray bar is associated with the switchable deflection means separately from the further spray bars, so that either the pre-accelerated coolant flow is fed to each spray bar by the conduit means, or deflection means associated with each spray bar feeds the coolant flow to the by-pass means.
  • At least one of the spray bars is supported by a support device, and the switchable deflection means is mounted on the support device.
  • the switchable deflection means is located by less than 5 m, preferably by less than 3 m upstream of the spray bar.
  • FIG. 1 (State-of-the Art) a schematic view of a device for supplying a plurality of spray bars with coolant;
  • FIG. 2 a schematic view of a device for cooling metal strips or the like rolled stock according to an example of one of the inventive embodiments.
  • FIG. 3 a schematic view of a device for cooling metal strips or the like rolled stock according to an example of another of the inventive embodiments.
  • a storage 4 that serves as a storage for coolant.
  • the coolant is fed to a distributor 6 or a manifold 6 via conduits.
  • the coolant can be fed to a plurality of spray bars 1 .
  • the spray bars 1 are provided with a plurality of outlets 7 for applying coolant to a metal strip from a respective outlets.
  • a measurement sensor 15 e.g., for measuring coolant pressure or volume flow
  • a regulator 9 e.g., for measuring coolant pressure or volume flow
  • a stop cock 8 e.g., a stop cock 8
  • These elements permit to monitor and adjust the cooling stream fed to respective spray bars 1 .
  • FIG. 2 shows a diagram of an embodiment example according to the present invention.
  • the coolant is stored, similar to the state-of-the art according to FIG. 1 , in a storage 4 . Contrary to the arrangement shown in FIG. 1 , the inventive embodiment according to FIG. 2 does not include any distributor 6 . Rather, coolant is fed from the storage 4 to each spray bar 1 separately via a conduit 2 .
  • the available coolant flow can be increased using pumps 11 , 11 ′ or booster-pump 11 , 11 ′.
  • the pumps 11 , 11 ′ for the coolant can be provided, e.g., with a by-pass 13 .
  • the by-pass 13 can be switchable, so that the coolant is delivered either by the pumps 11 , 11 ′ or by-passes the pumps 11 , 11 ′ and is simply forwarded through the conduit system 2 by the (static) pressure in the storage 4 .
  • the volume flow can be monitored with a measurement sensor 15 and/or regulated by a control valve or regulator 9 . Actual control of the volume flow per se is not subject of the present invention and can, e.g., be carried out with already known means of control technology.
  • the essential consists in that the inventive device is provided with the switchable deflection means 5 which can divert the pre-accelerated coolant flow away from the spray bar 1 .
  • the running or pre-accelerated volume flow can, e.g., be directed in a downflow or overflow pipe 3 .
  • Such coolant flow then can be, e.g., returned back to the storage 4 .
  • Further processing of the coolant is dispensed with because the coolant is not contaminated by means 5 in case of diversion.
  • the deflection generally includes two switchable shut-off valves or stop cocks or dampers so that the volume flow is forwarded either to the storage 4 or in the overflow pipe 3 .
  • An arrangement with one switchable damper is also possible.
  • the described device can provide an already pre-accelerated flow that, if needed, can be fed to the spray bar 1 via the deflection means 5 .
  • the means 5 can be switched on, e.g., by a sensor that registers presence or inflow or discharge of the coolant.
  • the temperature of the strip can be monitored with a temperature sensor.
  • the deflection means 5 actuator
  • the deflection means 5 can be switched off and on to control the inflow of the coolant (control value) through the spray bar 1 and its outlets 7 and onto the strip.
  • FIG. 3 shows a diagram of the cooling device according to another embodiment of the invention. Contrary to the device shown in FIG. 1 , here, a plurality of spray bars 1 are assembled to form a cooling group 10 , and another cooling bars 1 ′ are assembled to form a cooling group 10 ′. Within each of the cooling groups 10 , 10 ′, a deflection device 50 , 50 ′ is associated with each separate spray bar 1 , 1 ′, being located upstream of a respective spray bar 1 , 1 ′. I.e., the pre-accelerated volume flow can be fed to each spray bar 1 , 1 ′ by the associated deflection device 50 , 50 ′.
  • the deflection devices 50 , 50 ′ are located as close as possible to the spray bars 1 , 1 ′ in order to keep the time necessary for the volume flow to cover the path between the deflection location through the deflection means 5 and the spray bar low, whereby the reaction velocity or controllability of the system is noticeably improved.
  • the deflection means 5 , 50 , 50 ′ can generally be switched electrically, pneumatically, or hydraulically.
