Definitions
- the present invention relates to an apparatus and a method for cooling rolling stock, preferably in a rolling mill.
- Copper alloys, magnesium, titanium, nickel and other metals are also known cooling sections to perform similar influences on the rolling stock.
- 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. When using rolling oils, such as kerosene, which tend to spontaneously ignite and ignite very quickly, the temperature of the rolling stock must also be controlled in order to prevent such inflammation.
- spray cooling are known, which direct a cooling medium by means of nozzles on the belt.
- a cooling device is known, which applies the cooling medium by means of nozzles on the rolling stock.
- laminar coolings which direct a jet almost pressure-free on the rolling stock.
- a cooling device according to DE 197 18 530 A1 is particularly known for hot-rolled strip in direct current, in which the intensity of the cooling is controlled by relative adjustment of 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 spreads
- the cooling medium flows then in the direction of the beam.
- the cooling medium is entrained with the belt.
- a presence of cooling medium outside of the cooling device is usually undesirable, as a
- coated with cooling medium band of pulleys can contaminate the rolling hall itself, can contaminate the tape, can emit different emissions, such as smell and aerosols, can interfere with measuring devices, such as optical and radiometric instruments and an adverse effect on the rolling to roll gap to set the tribologically correct conditions in the nip may have.
- the known cooling devices are accordingly to avoid the
- present invention to provide a device for cooling of rolling stock, which has a more uniform heat transfer and reduces the pollution of the environment.
- 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 used to apply the
- Coolant provided on the rolling stock.
- a defined guidance of the cooling medium is achieved.
- a significantly longer exposure time of the cooling medium to the rolling stock can be achieved, and the action is geometrically defined and can be carried out in a controlled manner.
- Plant areas can be reduced.
- the surface can also be softened
- Cooling medium acts, be significantly increased because the cooling channel provides the opportunity to provide a geometrically defined area 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 can be reduced by the targeted guidance of the cooling medium along the rolling stock, whereby an energy saving can be achieved accordingly, since the cooling medium does not have to be placed under such strong pressure.
- the cooling chamber is between the rolling stock and a
- Chamber roof formed. In this way, 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 adjusted via the setting of the
- Volume flow can be compensated.
- the nozzle is formed so that the cooling medium in a in
- Substantially uniform flow into the cooling chamber can be conducted.
- a uniform flow By forming a uniform flow, a uniform distribution of heat transfer can be achieved.
- 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. This avoids that the supplied fluid flow adheres to the exit from the nozzle gap on the cooling chamber roof or preferably this follows and not as desired the nozzle gap in the direction
- Ribbon surface leaves and thus fills the cooling chamber.
- the cooling chamber is formed so that the cooling medium can flow through the cooling chamber in a substantially uniform flow.
- the cooling chamber extends counter to the strip running direction such that the cooling medium is guided counter to the strip running direction.
- the nozzle lies behind the cooling chamber in the direction of strip travel.
- 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 movement for laterally delimiting
- the device has in a preferred form at least one adjustable side wall, which at a defined distance to
- Bandwidth of the rolling stock to be cooled is positioned. This ensures optimal guidance of the flow in the cooling chamber and the formation of vortices is avoided.
- a discharge chamber can be attached to the cooling chamber in the flow direction to remove the cooling medium
- connection is when the discharge chamber is widened with respect to the cooling chamber in order to reduce the flow rate of the cooling medium in the discharge chamber with respect to 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
- Cooling medium is dependent on different parameters of the rolling stock, preferably depending on the temperature of the rolling stock, the material of
- an adjusting device can be provided for reversing the flow direction of the cooling medium in the cooling chamber, preferably by displacing an outer shell of the device.
- the cooling chamber can be moved away from the plane of the rolling stock.
- at least one outflow device may be provided with a device 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
- the method comprises applying a cooling medium to the rolling stock.
- the cooling medium is in a parallel to the rolling stock.

- the cooling medium 34 flows out of the nozzle 32 correspondingly further and comes into contact with the rolling stock 2.
- the cooling chamber 4 extends correspondingly when the rolling stock 2 is threaded substantially parallel to the rolling stock 2. 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.
- 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 such that the flowing in the nozzle 32 cooling medium 34 of the nozzle 32 in the

- 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.

- Cooling medium 34 to lead in a circuit since it is brought via the inlet 30 and the nozzle 32 in contact with the rolling stock 2 and then removed via the drain chamber 5 from the rolling stock 2.
