  • the jets of liquid impinging on the belt surface were visible in the light of a lamp and it could be seen that the fluid squeezed by the squeezing rollers 12 spread evenly across the width of the squeezing rollers 12, peeled off drop-shaped and finally dripped into the vertical tank 5.
  • the tinned steel strip samples treated in this way were subsequently analyzed with a C analyzer from Leco at a maximum oven temperature of 400 ° C.

  • the surfactant coating remaining on the tinned steel belt surface by the process according to the invention is composed of the surfactant coating adsorbed on the belt surface and of the coating, which results from the thickness of the liquid film squeezed off and its surfactant concentration.
  • the tinplate treated by the process according to the invention has a significantly lower energy requirement for drying in the drying device following the treatment device.

  • the surfactant solution sprayed onto the strip surface by the method according to the invention has such a short adsorption time, which is sufficient to ensure uniform adsorption of the surfactant layer on the tinplate surface, before the squeezing rollers 12 squeeze off the excess surfactant solution.
  • a short adsorption time it is not necessary to spray the liquid as evenly as possible on the tinplate surface via fine spray nozzles. Rather, it is sufficient - as provided for by the invention - to spray the surfactant solution onto the wet tinplate surface in a relatively coarse manner.
  • the advantage of spraying the surfactant solution in the form of thin liquid jets distributed over the width of the steel strip is that the risk of foaming in the tank in which the excess, in particular the squeezed, surfactant solution collects is substantially less than when using Spray tubes with nozzles, which would spray the surfactant solution finely atomized onto the tinplate surface.
  • the larger bore diameter of the spray tubes are less prone to foreign clogging than the smaller diameters of the spray nozzles required for the same application.
  • the tinplate strips investigated in the comparative experiments were examined with respect to their sliding friction value before and after the treatment according to the invention with a three-ball track test.
  • the surfactant coating does not reduce the sliding friction of the tin surface as much as the DOS coating.
  • the sliding friction is so good that when cutting the tinplate rings no scratches and grazes on the tinplate surface occur and the panels in the next processing stages can easily be tabulated from the package.
  • a further advantage over conventional greasing of tinplate, for example with DOS, ATBC (acetyltributyl citrate) or BSO (butyl stearate oil), is the satisfactory (pore-free) paintability of the tinplate surfaces treated according to the invention after usual storage periods (for example more than 12 months).
  • This advantage can probably be explained by the fact that the adsorbed surfactant molecules do not coagulate into droplets, as is often the case with DOS greases with> 4 mg / m 2 in the edge area of the tinplate boards. Paints that can not completely dissolve these droplets in the wet film on the tinplate surface then tend to form pores in the lacquer layer.
  • the method according to the invention can also be used in strip-tinning systems with horizontal rinsing cascades.
  • horizontal rinsing cascades up to 40 m 3 / h of rinsing water are sprayed onto both strip surfaces by spray registers with nozzles per rinsing step.
  • the rinsing water is then squeezed off and flows back into a storage tank under the respective rinsing stage, from where it is pumped back into the horizontal rinsing stage.
  • the inventive method can be used when the injection register before the last pair of squeezing rollers are replaced by the above-described tubes with holes, which according to the invention, the aqueous surfactant solution is sprayed onto one or both belt surfaces.
  • the surfactant solution is sprayed on the one hand through a pipe arranged above the top of the strip.
  • the aqueous surfactant solution is sprayed onto the underside of the belt by spraying the surfactant solution through a tube with holes on the squeezing roller resting against the underside of the belt.
  • aqueous surfactant solution This causes the aqueous surfactant solution to enter the gap transported the steel strip and the pressure applied to the underside of the belt squeezing roll, where the liquid is mixed with the water film on the underside of the belt and the belt surface in this way with the surfactant film "greased".
  • the squeezed-off surfactant solution also runs back into a storage tank, as in the described embodiment of the strip-tinning plant with a vertical tank, and can then be reused.
  • the method according to the invention, used in the treatment device 4 of the strip-tinning plant described can generally be used for reducing the coefficient of friction of metal strips provided with a metallic coating, for example also of special chromium-plated steel strip (ECCS).
  • ECCS special chromium-plated steel strip
  • the lacquer adhesion was tested after the sterilization test by cross-hatching and Tesatest according to EN ISO 2409.
