  • the present invention is directed to a method and apparatus for dynamically supplying a cooling device for cooling metal strip or other rolling stock with coolant.
  • the cooling device may in particular comprise one or more spray bars.
  • FIG. 1 Such a system according to the prior art is exemplary in the FIG. 1 shown.
  • the stored in the high tank 4 water is supplied via lines 2 a central manifold 6. From this common distributor 6, the water is supplied to the individual spray bars 1 via further lines.
  • this known arrangement has some disadvantages.
  • large cooling rates must also be as precisely adjustable or controllable as possible. However, this is made more difficult by the very large amounts of water used.
  • on and off operations can not be carried out satisfactorily fast by existing concepts, which usually include control valves, creating a switch-on of the Cooling often takes more than 10 seconds to reach the desired cooling rate.
  • a large strip length is not cooled at the desired cooling rate, resulting in quality losses of this band section result.
  • Another disadvantage is the high forces that act on switching operations of cooling on the piping systems or cooling systems.
  • Such pressure peaks can even lead to failure of the cooling system and thus the entire rolling mill.
  • the WO 2012/011578 A1 discloses a device for cooling a metal strip according to the preamble of claim 5 and a method for cooling a metal strip according to the preamble of claim 1.
  • the cooling device comprises a plurality of directed onto the metal strip spray nozzle groups, which are arranged in a common housing and at least one Supply line to be supplied with coolant.
  • the technical object of the invention is to provide an improved coolant supply, which in particular avoids or at least significantly reduces pressure surges during switch-on processes. Furthermore, the technical task may be to achieve a desired cooling rate faster than before in order to optimally supply a rolled strip with coolant.
  • the asked technical problem is solved by the features of the method for dynamic supply of a cooling device, in particular of at least one spray bar, for cooling metal strip or other rolling stock with 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 bypasses the cooling device and is guided into a return, as well as monitoring the presence and / or the temperature of a metal strip or other rolling stock to be cooled.

  • the method comprises at least the steps of providing a pre-accelerated or flowing coolant flow, wherein the coolant flow bypasses the cooling device and is guided into a return, as well as monitoring the presence and / or the temperature of a metal strip or other rolling stock to be cooled.
  • the pre-accelerated coolant flow is diverted to the cooling device in dependence on the presence and / or temperature of the metal strip or other rolling stock, the coolant flow being bypassed and guided into a return instead of the cooling device, the cooling device for cooling the metal strip or the other rolling stock is supplied pre-accelerated.
  • the pressure loss of the pre-accelerated coolant flow when bypassing the cooling device and the pressure loss when supplying the pre-accelerated coolant flow to the cooling device are less than 50%, preferably less than 20% or even less than 10%. Preferably, both values are substantially the same.
  • the flow resistance for the coolant flow at bypass or line is substantially equal to or different from the cooling device as stated above.

  • the deflection of the coolant flow is less than 5 m, preferably less than 1 m upstream of the cooling device (1) (so that the path of the coolant flow between the location of the deflection (5) and the outlets (7) of the cooling device (1). is kept as low as possible to cool the belt).
  • the volume flow of the coolant or coolant flow to be deflected is more than 150 m 3 / h and preferably more than 400 m 3 / h. Especially in view of such large volume flows, the present invention is particularly advantageous.
  • the apparatus initially comprises a cooling device for cooling metal strip or other rolling stock, which comprises at least one spray bar with coolant outlets for dispensing the coolant onto the metal strip. Further, the apparatus includes conduit means for directing a flow of coolant from a source of coolant to the spray bar, and bypass means for directing the flow of refrigerant from the conduit means into a return line. Switchable diverting means of the apparatus are adapted to switchably direct the flow of refrigerant through the conduit means to the spray bar or to divert the flow of refrigerant from the conduit means into the bypass means.
  • the device may comprise at least one valve for adjusting a volumetric flow of the coolant flow (flowing) through the conduit means, the diverting means being located downstream of the control valve.
  • the switchable bypass means may each comprise at least one switchable flap for directing the coolant flow to the spray bars or into the bypass means.

  • a pump for increasing the volumetric flow provided by the source.
  • the pump can be bypassed by means of a bypass through the coolant flow.
  • a bypass through the coolant flow.
  • the water pressure can be provided by a high tank, for example.

  • the first and the second cooling group are fed or supplied separately by the source with coolant.
  • the volume flow to each individual cooling group can be increased separately by a pump.
  • the device comprises a plurality of spray bars, wherein each spray bar is assigned a switchable diverting means separately from the further spray bars, so that either the pre-accelerated coolant flow can be fed to each spray bar via the conduit means or the coolant flow can be supplied to the bypass means via the diverting means assigned to the spray bar.
  • At least one of the spray bars is supported by a support device and the switchable diverting means is mounted on this support means.
  • the switchable diverting means is arranged less than 5 m, preferably less than 3 m, upstream of the spray bar.
  • FIG. 1 Pictured is a high tank 4, which serves as storage for coolant.
  • the coolant is usually a distributor 6 and a manifold 6 can be fed. From this distributor 6, the coolant can be supplied to a plurality of spray bars 1.

  • FIG. 2 shows a schematic of an embodiment of the invention. Coolant is similar to the prior art according to the FIG. 1 provided by a memory 4. In contrast to the arrangement according to FIG. 1 includes the embodiment of the invention the FIG. 2 However, preferably no distributor 6. Rather, each spray bar 1 is fed separately via a line 2 coolant from the memory 4.
  • the provided coolant flow can be increased by a pump 11, 11 'or booster pump 11, 11'.
  • this pump 11, 11 'for the coolant flow for example, by a bypass 13 can be bypassed.

  • the volume flow can also be monitored by a measuring transducer 15 and / or be adjustable by a control valve 9.
  • the specific regulation of the volume flow is not core of the invention and can be done for example by already known control engineering measures.
  • the device according to the invention has switchable deflection means 5 which can redirect a pre-accelerated coolant flow away from the spray bar 1.
  • a flowing or pre-accelerated volumetric flow can first be conducted into an overflow or overflow 3.
  • Such a coolant flow may, for example, subsequently follow the reservoir 4 to be led back.
  • a further treatment of the coolant is eliminated, since the coolant is not polluted when diverted by the means 5.
  • the deflection means 5 may generally comprise two switchable shut-off valves or valves, so that a volume flow is supplied to either the spray bar 1 or the return 3. However, it is also an arrangement with only one switchable flap possible. By the described arrangement, an already pre-accelerated coolant flow can be provided, which can be supplied to the spray bar 1 by the deflection means 5 as required.
  • the means 5 can be switched, for example, by means of a sensor which registers the presence or the entry or exit of a band. Alternatively or additionally, the temperature of the belt can be monitored with a temperature sensor. Depending on the temperature as a control variable, the deflection means 5 (actuator) can thus preferably be switched or set in order to adjust the inflow of the coolant (control variable) via the spray bars 1 and their outlets 7 to the belt.
  • FIG. 3 discloses a schematic of a cooling device according to another embodiment of the invention. Unlike in the FIG. 1 As shown, several spray bars 1 are combined to form a first cooling group 10 and further spray bars 1 'are combined to form a second cooling group 10'.

That is, each spraying bar 1, 1 'can be supplied with a volume flow pre-accelerated by an associated deflecting means 50, 50'.
  • the deflecting means 50, 50 ' are preferably located as close as possible to the spray bar 1, 1' to be supplied, in order to minimize the time needed for the distance between the location of the deflection by the means 5 and the spray bar, whereby the reaction speed or the controllability of the system is significantly improved.
  • the deflection means 5, 50, 50 ' can generally be switched, for example, electrically, pneumatically or hydraulically.
