Definitions

  • the invention relates to a coating system for coating of band-shaped material with coating material, in which the coating tape-shaped material led into the coating bath and between two partially immersed in the coating bath Coating rolls through from the coating bath out and past the scraper nozzles.
  • Coating systems for coating strip material have long been known in many forms. With such systems should be band-shaped material of different types, namely Metal tape or plastic tape, fabric tape, paper tape with different Coatings from liquid media, e.g. B. with melted Zinc, tin or alloys thereof or colored material coated become.
  • the coating bath is designed as a molten bath, in which the materials are melted so that they liquefy for the coating.
  • Coating systems of the type mentioned at the beginning have been around long known, e.g. B. from JP-OS 55128570.
  • this coating system is a pulley to guide the tape through the Bath provided with their bearings completely in the coating bath is immersed, and there are two partially in the coating bath immersed coating rolls provided, the Bearings are also immersed in the coating bath.

  • the deflection roller is like this under the coating rollers arranged in the coating bath that the band-shaped material vertically from the bottom up through the gap between the two Coating rolls runs through.
  • the tape is first with the help of the deflection roller in a position from which it from bottom to top through the gap between the two coating rolls runs through. Because in this coating system Storage of the coating rollers and also the deflection roller in the coating bath are immersed, they are due to high friction and flow stress, but also thermal stress, exposed to high wear and tear and must be replaced frequently become. An exchange is only possible with a standstill the complete line and a lot of time is possible because the rollers have to be lifted out. This leads to an interruption of continuous operation and after exchanging too many work steps until the system is returned to its working state is. In addition, in this known system fast running of the strip to be coated is only possible to a limited extent. Especially at higher speeds, material from the Bath torn out in excessive quantities because of the coating rolls are arranged at a certain distance from each other. Corresponding needs a larger amount of material using the wiping nozzles be stripped.
  • JP-OS .. 55085664 known the guide rollers through which to be coated Belt runs, on or under the surface of the coating bath to be arranged so that the distance between the surface of the coating bath and the contact point between the one to be coated Tape and a roll within the diameter of the Role.
  • this plant is next to the guide roller at least one guide role in the coating bath immersed so that their bearings in the coating bath are located. This also results in this arrangement the mentioned signs of wear for the bearings the need to switch off the appropriate roles Exchange system.
  • the invention is based on the object of a coating system to create the kind mentioned at the beginning moving parts have a longer life, and the speed of the tape to be coated.
  • This object is achieved in that the bearings of the coating rollers lie outside the coating bath.
  • the galvanneal process in particular has advantages due to the short immersion times in the coating bath.
  • Only one deflection roller can be provided, which is outside of the coating bath. In this case it works Roll with the least friction loss. If the pulley is outside the coating bath or if there is no deflection roller is provided, the coating material container to be made particularly small.
  • the coating rolls are advantageously horizontal and vertically movable, so that the system to different strengths tape to be coated is customizable.
  • the wiping nozzles are preferably heated electrically. This makes them easy to regulate.
  • oxidation of the coating especially in the case of metal coatings, can be caused by a closed atmosphere, e.g. B. by N 2 , effectively prevent.
  • N 2 a closed atmosphere
  • Under a cover it is possible to maintain the viscosity of the coating, so that, together with high temperatures of the stripping medium, excess coating material can be wiped off safely. If the layer material has high viscosities, it is also readily possible to increase the speed of the strip to be coated.
  • hot stripping metallic materials temperatures up to 600 ° C can be used. This results in considerable advantages in the galvanneal process.
  • the coating rollers but also the deflection roller, if they are in the coating bath is immersed, preferably with scrapers provided to scrape off slag.
  • the band-shaped material can be metal band, plastic band, fabric band or paper tape. Then different accordingly Coating baths with appropriately set coating temperatures used.
  • a coating material such. B. zinc, aluminum, tin and alloys of various types can be used and both liquids and Color powder, the z. B. dissolved in water can be used.
  • the coating systems have a coating material container 1 in which the coating bath 2 is made of coating material.
  • the coating material can be made of molten tin, zinc, aluminum or alloys of various types exist or also from color powder that is water-soluble.
  • the coating material container 1 a coating kettle in which the coating bath 2 is located.
  • the coating bath In the coating bath are a front coating roll 3 and a rear coating roller 4 immersed, such that their bearings 5 and 6 are above the upper bath level 7 of the coating bath 2 are.
  • the coating bath 2 is also a deflection roller in this embodiment 8 immersed, the bearing 9 is also above the upper Bath levels 7 of the coating bath 2 are located.
  • the front and rear coating roller 3 or 4 can be driven or neither.
  • the coating rolls 3 and 4 are characterized by a small Gap separated from each other, so that what is to be coated Band 10 runs through the gap so that the rule non-driven rear coating roll taken becomes.
  • Both the front and rear coating rolls 3 and 4 and the deflection roller 8 are both vertical and horizontal adjustable. This makes the coating system adjustable to different thicknesses of the strip to be coated, to be able to set an optimal coating.
  • the strip 10 to be coated becomes the guided rear pulley 8, directed around this, to the rear coating roller 4 and through the gap between the front and rear coating rollers 3 and 4 from the coating bath promoted.
  • the coating bath can consist of different Liquids exist around the tape 10 with a coating to provide.
  • the bath can have a temperature of up to 700 ° C to have.
  • the coating to be coated becomes Band 10 preheated in a preheating oven 11, then in the coating bath 2 is immersed and thereby around the deflection roller 8 directed towards the rear coating roller 4 to this Roll around and through the gap between the two coating rolls 3 and 4 out of the coating bath.
  • the rear coating roll 4 can on its surface have a structure, for example a profile or a roughness, to evenly coat the surface to be coated To reach the band on this band page.
  • the two coating rollers 3 and 4 are adjustable minimal gap from each other.
  • the front coating roll 3 has regardless of whether it is powered or not the tendency to coat material in the cavity between the bath surface and the belt and its peripheral surface to bring in and thus a uniform coating of the to be coated Effect on this side of the tape.
  • Both sides of the band of the strip 10 to be coated have after exiting excess at the gap between the coating rollers 3 and 4 Coating material. Taking coating material with you 2 is particularly small because the axes of the Coating rolls 3 and 4 above bath level 7 of the coating bath 2 are located.

  • the parts of the coating rolls 3 and 4 which are arranged above the upper bath level of the melt pool and the wiping nozzles 12 and 13 are arranged in a cover 14 in this embodiment.
  • the cover 14 enables the coating material to be stripped off under improved conditions.
  • the cover 14 forms a space in which the stripping can be carried out in a closed atmosphere which prevents skin and slag formation of the coating material.
  • the closed atmosphere can be, for example, an N 2 atmosphere or another gaseous atmosphere.
  • the gaseous atmosphere for example nitrogen or air, is emitted from the scraper nozzles.
  • the gaseous atmosphere can preferably be preheated in the stripping nozzles.
  • the wiping nozzles can be electrically heated, which has the advantage of simple temperature control.
  • the outlet temperatures of the stripping gas can be up to 600 ° C for so-called hot stripping.
  • Both the front and the rear coating rolls 3 and 4 have a relatively large diameter in order to avoid splashes of the coating medium by centrifugal forces at the relatively high belt speeds of, for example, 300 meters per minute. In order to remove slag adhering to the coating rolls or excess coating materials, scrapers attack their outer peripheral surfaces.
