Definitions

  • the invention relates to a method for the homogeneous, contactless tempering of surfaces to be tempered, which are primarily not endless, and a device therefor.
  • temperature control is required in many areas, for example when flat plates have to be cooled or heated, but also when e.g. B. glass surfaces in glass production or processor units or the like must be cooled or heated.
  • Previous cooling systems are either very complex, or kept quite simple, e.g. B. by blowing air or with other fluids, especially water or oil, which has the disadvantage that always unfavorable, uncontrolled flow conditions form on the surface, which become a problem when a specially defined temperature control is required.
  • a disadvantage of all these types of heating is that they are very complex or, in particular with different thicknesses, lead to different heating results. A small, area-wise control of the heating is not possible.
  • a heat treatment is carried out on a steel strip by blowing a gas jet onto the steel strip from a nozzle, the nozzle protruding perpendicularly from a flat surface of a collector into a tube H from the surface, the outlet opening of the nozzle being at a distance from the steel strip by To heat, cool or dry steel strip, the gas quantity density depending on the distance from the nozzle to the strip.
  • an apparatus for cooling a rolled product such as a steel strip which comprises a box containing pressurized gas, the box comprising a plurality of strips forming conduits, each strip having at least one gas outlet located on at least one Surface of the rolled product is directed, the openings of each strip being transverse to the longitudinal or moving direction of the rolled product, each space between two adjacent strips having a depth in a direction perpendicular to the surface of the rolled product and another in the longitudinal direction of the rolled product, which is so sufficient is that the gas can be drawn off without interruption.
  • the object of the invention is to provide reproducible, systematic, homogeneous, contact-free temperature control of surfaces that are not primarily infinitely hot to a defined surface temperature within a few seconds.
  • the cooling media used are air gases, mixed gases but also water or other fluids.
  • the heating media used is preferably hot gases.
  • the surface to be temperature-controlled can be moved in the X, Y or Z plane by means of robots or linear drives, it being possible to specify the movement trajectories and the speeds of the surfaces to be cooled in any desired manner.
  • the oscillation around a rest position in the X and Y planes is preferred. Further oscillation in the Z plane (i.e. the height) is optional.
  • Cooling on one or both sides is also easily possible.
  • the temperature control units according to the invention consist of nozzles which are arranged at a certain distance from one another.
  • the geometry of the nozzles i.e. the outlet opening, ranges from simple cylindrical geometries to complex geometrically defined designs.
  • the temperature control unit is designed in such a way that there is sufficient space for the medium flowing out of the hot plate so that there is no crossflow on the surface to be cooled.
  • the intermediate spaces between the nozzles or rows of nozzles can be subjected to an additional cross flow in order to increase the temperature control rate and thus quasi suck off the temperature control medium flowing out of the hot plate.
  • this cross-flow should not impair the temperature control medium flowing from the nozzle to the plate, i.e. the free jet.
  • the flow pattern to be preferred follows a honeycomb-like structure on the surface to be cooled.
  • the cooling is preferably carried out with at least one cooling sword, the cooling sword being a plate-like or cylindrical element which can additionally taper from a base to an outflow bar, at least one nozzle being introduced in the outflow bar.
  • the sword is hollow, so that the nozzle can be supplied with a temperature control fluid from the hollow sword.
  • the nozzle (s) can be spatially spaced apart from one another with wedge-like elements, wherein the wedge-like elements can also narrow the space for the flowing fluid towards the nozzle.
  • a plurality of swords are preferably arranged next to one another, the swords being offset from one another.
  • temperature control is also carried out with staggered points with respect to one another, the points cooling homogeneously into one another and the outflowing fluid being sucked into and discharged into the area between two swords.
  • the element to be tempered e.g. B. a plate to be tempered
  • moves here so that the movement of the plate on the one hand and the offset arrangement of the nozzles on the other hand ensures that the tempering fluid flows over all areas of the plate, so that a homogeneous temperature control is achieved.
  • the temperature control device 1 has at least one temperature control sword 2.
  • the temperature control sword 2 is elongated and has a flap-like design and has a temperature control sword base 3, two temperature control sword broad sides 4 extending away from the temperature control sword base, two temperature control sword narrow sides 5, which connect the temperature control sword wide sides 6, and a free nozzle .
  • the temperature control sword 2 is hollow with a temperature control sword cavity 7, the cavity being enclosed by the temperature control sword broad sides 4, the temperature control sword narrow sides 5 and the nozzle edge 6, the temperature control sword at the base 3 being open.
  • the temperature control sword base 3 With the temperature control sword base 3, the temperature control sword is inserted into a temperature control sword frame 8, wherein the temperature control sword frame 8 can be placed on a hollow fluid supply box.
  • a plurality of nozzles or openings are introduced which extend into the cavity 7 and thus allow fluid to flow out of the cavity to the outside through the nozzles 10.
  • Nozzle channels 11 extend from the nozzles into the cavity 7, which spatially separate the nozzles from one another at least in the region of the nozzle edge 6.
  • the nozzle channels are preferably wedge-shaped in cross section, so that the nozzle channels or nozzles are separated from one another by wedge-shaped webs 12.
  • the nozzle channels are preferably designed such that they expand towards the cavity 7, so that an inflowing fluid is accelerated by the narrowing of the nozzle channels.
  • the broadside of the temperature control sword 4 can be designed to converge from the temperature control sword base 3 to the nozzle edge 6, so that the cavity narrows towards the nozzle edge 6.
  • the temperature control narrow sides 5 can be designed to be converging or diverging.
  • thermocontrol swords 2 There are preferably at least two temperature control swords 2, which are arranged parallel to one another with respect to the broad sides, wherein the temperature control swords 2 are offset from one another by half a nozzle spacing with respect to the spacing of the nozzles.
  • the nozzles 10 can also be designed to be elongated in alignment with the nozzle edge, but the nozzles can also be round, oval in alignment with the Nozzle edge or oval transverse to the nozzle edge to be hexagonal, octagonal or polygonal.
  • nozzles are also elongated with respect to the longitudinal extent of the nozzle edge, in particular oblong oval or oblong polygonal, there is a rotation of an emerging fluid jet ( Figures 10 , 11 ), whereby an offset arrangement by half a nozzle distance results in a temperature control pattern on a plate-like body ( Figure 10 ), which is offset accordingly.
  • the corresponding speed profile also gives a corresponding distribution ( Figure 11 ).
  • a device for tempering ( Figure 12 ) has z. B. two arrangements of temperature control swords 2 in a temperature control sword frame 8, wherein the temperature control sword frame 8 are formed with corresponding fluid feeds 14 and in particular on the side facing away from the temperature control swords 2 with a fluid box, in which fluid under pressure is present, in particular by the supply under pressure standing fluid.
  • a cooling medium is accordingly used, which is preferably supplied to a temperature control sword, with the cooling medium preferably being supplied centrally to the fluid supply box in a plurality of temperature control swords and being distributed from there to the temperature control swords.
  • the temperature control device When using the temperature control device for heating a corresponding plate or a corresponding object, it is advisable for the heating to take place via gaseous media.
  • gaseous media can be correspondingly heated to a target temperature outside the temperature control device.
  • Such heating is possible with conventional wind heaters, for example.
  • the fluids can be heated by direct or indirect heating, in particular by burners, jet pipes, electrical resistance heating and the like.
  • a circuit board is heated by means of purely convective heating with a gas having a temperature of 1100 ° C. and a heat transfer coefficient of 200 W / m 2 / K.
  • the heating curve (temperature in ° C over time in s) with this purely convective heating is in Figure 13 shown. It can be seen very well that the temperature quickly rises to a temperature above Ac3, i.e. the austenitizing temperature, which, for example, is 900 ° C. for a manganese-boron steel, and this method is therefore also well suited for hot forming, for example.
  • the austenitizing temperature which, for example, is 900 ° C. for a manganese-boron steel
  • a flat circuit board does not have to be used for this, but a correspondingly preformed component can also be heated.
  • only a partial area of the board is tempered, ie heated from room temperature (approx. 20 ° C.) to over Ac3 (approx. 900 ° C.).
  • room temperature approximately 20 ° C.
  • Ac3 approximately 900 ° C.
  • only these areas are hardened by the partial austenitization, and other areas of the board remain soft after a hot-forming step (not described in more detail here).
  • the setting of this zone can - depending on the design of the nozzle swords - be set quite precisely and, in this example, even temper areas within the board from at least 60 mm x 60 mm to a few millimeters.
  • edge areas of the board would be affected, they can be tempered even more precisely by appropriate movement through the nozzle field if parts of the board do not pass through the nozzle field.
  • the board can also be preheated - for example by a roller hearth furnace or other storage furnace.
  • a movement device 16 is provided, the movement device being designed in such a way that it can guide a body to be temperature-controlled between the opposing temperature-control sword arrangements in such a way that the body to be temperature-controlled can be cooled on both sides.
  • the distances between the nozzle edges 6 to the body to be tempered are z. B. 5 to 250 mm.
  • the tempering pattern moves accordingly Figure 10 over the surface of the body to be tempered, the medium flowing out of the hot body between the temperature control bars 2 being sufficient Finds space to flow away and therefore no crossflow occurs on the surface to be tempered.
  • the intermediate spaces can be acted upon with an additional transverse flow by means of appropriate flow media in order to suck off the medium flowing onto the body to be tempered between the swords.
  • An advantage of the invention is that a homogeneous temperature control of elements to be temperature-controlled is possible, which is inexpensive and has a high variability with regard to the target temperature and possible throughput times.
