Definitions

  • the invention relates to a method for applying a coating on a web-like material, the material of the coating being in the molten state by means of at least one rotating roller is applied, solidified by cooling and with connects the substrate, being at least on a portion of the shell of the roller Film of the material of the coating is generated and the substrate at such a distance is guided relative to the roller that the material of the Coating flows continuously from the roller onto the surface of the substrate as well as a Device for applying a coating to a web-like material, the Material of the coating in the molten state by means of at least one rotatable Roller can be applied, after which it solidifies by cooling and converges with the web Connects well, with a film of the material of the Coating can be produced and the web-like material at such a distance from the roller It is feasible that the material of the coating is continuously removed from a contact area the jacket of the roller flows onto the web-like material.
  • Such immersion processes are characterized by a ratio to the thickness of the desired Coating very high amount of the material used for coating, because the immersed components or tapes at least once completely below the surface the melt must reach.
  • Large amounts resulted from the large amounts used Dimensions of the immersion baths, high energy and insulation requirements and - especially with the Use of high-quality materials for coating - a high capital commitment. moreover undesirable deposits form in immersion baths with metallic melts, which Can negatively affect the quality of the coating.
  • at Coating of sheets with immersion processes always always coated both sides. A coating on a single side or different coatings both sides are not possible.
  • the object of the invention is a further method and an apparatus for propose molten coatings, by means of which the size of the generic device can be significantly reduced.
  • this object is achieved according to the invention solved in that the liquid material of the coating from an inner cavity a roller is promoted by breakthroughs on the shell of the roller.
  • the Generic device has a roller of a device according to the invention inner cavity that is covered with pressurized liquid material of the coating can be acted upon and is provided with openings for the liquid material to exit the cavity on the jacket.
  • the invention leads to surprisingly constructive simple solutions and compact designs. Different coatings too both sides are possible.
  • the amount of coating material remaining in the system can advantageously be albeit with increased manufacturing effort - can be reduced if the breakthroughs the jacket of the roller individually over essentially radially extending channels with a pressure line running axially inside the roller are connected. By a Reducing the diameter of this pressure line and the channels will make the empty volume of the Roller and thus the amount of material used significantly reduced.
  • the invention then leads to a particularly easy-to-use method if the Roll is mounted stationary and the web-like material in its longitudinal direction relative to the stationary roller is moved past this. Is the web-shaped good in addition Contact area moved essentially vertically upwards, so the supports Acceleration of gravity the formation of a film of the material of the coating on the Top of the roller.
  • a roller movable in a direction that a component perpendicular to the surface of the possesses web-like estates By adjusting the distance between the roller and Substrate can have different flow properties of the material of the coating be taken into account.
  • the coating can be removed by removing the roller interrupted by the substrate very easily and at a later point by re-delivery to be resumed. If the roller is movably supported in its axial direction, then can apply the coating to the substrate without any significant effort can be varied.
  • coatings can be coated with, for example, the half the width of the tape.
  • the invention is used particularly advantageously in the coating of metallic Tapes, when coating with metals, or when the melting point of the coating is less than the melting point of the substrate.
  • a roller of the device according to the invention can be heated be designed around a premature solidification of the material of the coating submissions.
  • the roll mantle may cover part of its circumference before entering be actively heated in the contact area from the outside.
  • the shape described above of radial channels in the roller also enables a reduction in the outer ones Dimensions of the generic device by the arrangement of additional Heating elements inside the roller.
  • the substrate can also be removed before entering the Contact area from the outside, actively heated and, if necessary, exposed to protective gas become.
  • the flow of material from the jacket of the roller to the surface of the substrate is then special easy to set if the directions of movement of those to be coated are in the contact area Surface and the shell of the roller are opposite to each other.
  • the openings in the grooves leading to the surface of the roller Sheath are arranged that are helical with a constant slope or perpendicular to Run longitudinally and equidistantly around the longitudinal axis of the roller. So it becomes even Distribution of the material of the coating on the surface of the roller is achieved.
  • a device 1 according to FIG. 1 for coating a web-shaped substrate on both sides 2 in the form of a steel strip with a metallic material, for example one Zinc alloy, comprises two oppositely arranged devices 3a and 3b for the one-sided coating, between which the substrate 2 continuously in one Direction 4 is led vertically upwards. Passes through before entering device 1 the substrate 2 is an inductive heater 5.
  • the devices 3a and 3b each comprise a roller 6, one arranged below it Collecting device 7 and a housing 8 comprising both Roller 6 in a bath 9 formed by the liquid material of the coating.
  • the grooves 11a and 11b represent alternative embodiments represents, which suitably relate to the overall roll surface.
  • the devices 3a and 3b can easily be attached different properties of the substrate 2, the metallic liquid and the desired thickness of the coating can be adjusted. By increasing the distance There may also be interruptions between substrate 2 and roller 6 in the radial direction 18 of the coating.
