Definitions

  • Cooling device for cooling a metallic material and method for its production and operation
  • the invention relates to a cooling device for cooling a metallic material, in particular after a rolling of the metallic material. Moreover, the invention relates to a method for operating this cooling device and to a method for producing or selecting a cooling beam for such a cooling device.
  • WO 2016/189903 A1 discloses a binary approach in which overcooling of the metallic material in the edge region is compensated by the provision of width masking at the edges of the metallic material in conjunction with coolant collecting containers.
  • European patent EP 2 155 411 B1 also discloses a solution for reducing a non-uniform temperature distribution, in particular at the edges of a metallic material. Again, masks are provided for covering the edges, but these masks are displaced or adjustable in the width direction and also allow a certain amount of coolant to the edges of the goods to be cooled.
  • European patent specification EP 2 986 400 B1 discloses a cooling beam with a plurality of chambers, which can be charged individually with the coolant.
  • different pressures or volume flows for the coolant can be adjusted over the width of the nozzle bar.
  • the pressure or volume flow distribution of the coolant over the width of the Cooling beam can be adapted to the actual course of the temperature over the width of the metallic material in the inlet of a cooling device.
  • the invention has the object, a known cooling device and known methods for their production and operation in such a way that the cooling effect generated by the cooling device can be better adapted to the metallic material to a real inlet temperature distribution.
  • the cooling device according to the invention is characterized in that the density of the cross-sectional areas of the outlet openings of thedeffenbeaufschlagungsetti is distributed and dimensioned in the width direction of the cooling beam in accordance with the amount of slope of the distribution of the temperature of the metallic material over its width before the inlet under the chilled beam.
  • density of the cross-sectional areas in the context of the present description means the sum of the cross-sectional areas of the outlet openings of the coolant charging elements per unit area of the cooling beam. In simple terms, this density refers to the ratio of exit area for the coolant to area unit on the chilled beam.
  • cross-sectional area may also mean the cross-sectional area of a spray spot on the material to be cooled. Due to the claimed distribution of the density of the cross-sectional areas in accordance with or according to the amount of the slope of the distribution of the temperature of the metallic material over its width, it is possible, the cooling performance - even when exposed to the metallic material with a constant coolant volume flow or coolant pressure - very adapt much more closely to the actual temperature conditions in the metallic material. In particular, progressive or degressive temperature curves can be compensated or cooled very accurately.
  • the slope becomes progressively greater toward the edges and, accordingly, the density of the cross-sectional areas of the outlet openings of the coolant-applying elements is to be reduced.
  • the temperature increases towards the edges, for example, then it requires more cooling, which is achieved by increasing the coolant outlet area of the loading elements in the corresponding width ranges.
  • the density of the cross-sectional areas of the outlet openings of thedeffenbeetzschlagungs- elements is represented or can be represented by the projected in the width direction of the cooling beam distance between two adjacentdeffenbeetzhausungs instituten.
  • this Projected distance in the width direction of the cooling bar is increased toward an edge of the cooling bar, when the temperature of the metallic material drops to this edge of the cooling bar out. Due to the drop in temperature then less cooling power is required in these width ranges, which is achieved in that the projected distance between individual, in particular adjacent nozzles is increased. This is equivalent to a reduction in the density of the cross-sectional areas of the outlet openings of thedeffenbeetzschungs institute.
  • the density of the cross-sectional areas of the exit openings need not be zero if the amount of the slope is zero, ie if the temperature distribution is constant in the width direction.
  • the density of the cross-sectional areas of the exit openings in the width direction is also constant over the corresponding width section, but typically not equal to zero, more precisely greater than zero.
  • the invention offers the advantage that, even when the material to be cooled is subjected to a constant volume flow or a constant pressure of the coolant over the width of the cooling beam, the exact adaptation of the cooling power to the actual temperature profile is already solely due to the corresponding claimed density distribution of thedeffenbeaufschlagungsetti can be achieved with their respective cross-sectional areas.
  • the volume flow or the pressure of the coolant in individual width ranges can also be set differently in order to adapt the distribution of the coolant and the cooling capacity in the width direction to the real temperature distribution.
  • the cooling beam may preferably be formed with a plurality of individual cooling chambers, which are subjected to different amounts of coolant. This is typically done via the individual chambers associated valves, which are controlled by a control device according to individually.
  • the above object of the invention is further achieved by a method for producing or selecting a cooling bar for a cooling device according to one of the preceding claims.
  • the claimed selection of a cooling bar relates to the case where the user has a plurality of different cooling bars in stock and he has to select a suitable cooling bar for each particular application.
