Definitions
- metal sheet with deep-drawing qualities provided on one side with a metallic coating is required, the side of which is left without coating and which is on the outside of the finished vehicle must be undamaged and paintable, while the coated, in particular galvanized side which is on finished vehicle is inside, the coating is protected against corrosion.
- Various methods have already been developed for providing metal strips with metallic coatings on one side, but so far they have not given satisfactory results.
- a two-sided coating is first applied in a previously conventional manner by being dipped into the liquid coating medium, which coating is then removed again on one side by electrolytic means. Aside from the high energy costs that this process requires, it is impossible to completely remove the influence of electrolytic dezincification from the side on which the coating is to be retained.
- Another known method proposes to apply a chemical to one side of the sheet, which prevents the metallic coating material from sticking permanently.
- this requires a complex pretreatment of the sheet to be degreased, which also requires new operating systems for this special treatment and must lead to profound changes to existing systems for double-sided coating.
- the chemicals contaminate the zinc bath and do not remain without effect on the further treatment of the zinc-free surface of the strip, especially with regard to later painting.
- a method for one-sided metallic coating of tapes which provides for the tape to be coated to be passed in the stretched state at a slight distance above the level of the liquid coating medium in a container and at the same time to produce an upward flow in the interior of the bath, which causes wetting of the lower surface of the strip with the coating medium.
- the known method also provides for this side to be provided with a gas cushion by which the coating medium is pressed away.
- the disadvantage of this method is that the uniformity of the coating can hardly be guaranteed because, on the one hand, the strip guided horizontally over the bath surface cannot have a precisely defined distance from the bath surface due to rolling defects and uneven running over the deflection rollers, and on the other hand the flow generated in the bath cannot be produced so uniformly that uniform wetting of the belt surfaces must be ensured.
- the German published patent application 28 19 142 has disclosed a method and a device for one-sided coating, in which the strip to be coated is guided around a deflection roller located above the coating medium, under which, parallel to the axis, a scooping roller is partially inside, in order to create exact geometric relationships of the coating medium is arranged, the scoop roller conveying the coating medium out of the container into the gap between scoop roller jacket and belt surface and through it. Acknowledging this The solution is that an exactly adjustable layer thickness can be achieved due to the forced guidance of the molten metal through the gap between the deflection roller and scoop roller, excess coating material being squeezed off.
- the layer thickness should be adjustable by changing the contact pressure.
- the object of the present invention is to create, on the basis of the last-described state of the art, a device for one-sided coating of continuous strip, which can be used as an additional device for existing systems for double-sided coating of metal strip, for a perfect, uniform metallic coating of the continuous strip with little construction effort permitted with exact adjustability of the coating thickness.
- a method which is characterized in that the coating medium is conveyed against the surface of the belt at least in the amount necessary for applying the desired coating thickness against the direction of belt travel.
- the proposed method thus differs from the prior art in that the coating medium is no longer "pressed” through the gap between the scoop and deflection roller, but in that the strip surface is wetted with the coating medium, with a flow directed against the strip passage direction against the strip surface is produced.
- a device which is characterized in that the scoop roller is rotated in the opposite direction to the belt running direction and a slight gap is provided between the scoop roller shell and the belt surface, which allows the roll to rotate freely.
- This proposal allows an optimal coating in that the dipping roller immersed in the coating medium, which rotates in the opposite direction to the tape running direction, due to its friction between the outer surface and the coating medium, the latter in the area of Gaps between scoop roller and belt and not only creates a constant supply of coating medium there, which can be applied to the belt in a constant amount and quality, but also creates a flow that presses the coating medium against the belt.
- the coating thickness is particularly uniform because without mechanical squeezing or pressing on the coating medium as in the prior art, the sufficiently offered coating medium, as it is in the Practice has shown, brings a particularly good coating result.
- the scoop roller is mounted in a container which is arranged above a storage container, preferably the melting tank, from which the coating medium can be pumped into the first container and returned to it.
- a storage container preferably the melting tank
- an adjustable weir or similar device is provided on the container holding the coating roll in order to control the level of the strip surface of the coating medium.
- Such a weir forms an overflow for the coating medium pumped into the container, which runs back into the storage container directly as a result of the arrangement of the container above it.
- an always defined and adjustable bath surface can be guaranteed, so that the immersion depth of the scoop roller, which is important for the thickness of the coating to be applied, can be set exactly.
- the amount of coating medium scooped can thereby be controlled very precisely.
- a distribution channel which extends into the area of the gap between scoop roller jacket and belt surface and extends approximately over the bandwidth, with which additional coating medium can be brought from one of the containers into the coating zone.
- the supply of coating material in the gap between the deflection roller and the coating roller can be improved if necessary.
- the deflecting roller in the strip transport direction behind the gap between the strip surface and the coating roller jacket has a nozzle knife for controlling the desired layer thickness and / or a device for introducing crystallization nuclei is provided in the layer by means of a gas stream. While the nozzle knife can regulate the thickness of the coating in a known manner, the solidification behavior of the applied coating medium can be influenced by the introduction of crystallization nuclei, so that the quality of the surface can be influenced in a positive way.
- Fig. 1, 1 is the protective gas housing in which the device according to the invention is housed.
- 2 denotes the ceramic-coated deflection roller for the continuous sheet metal strip B to be coated on one side with zinc.
- the direction of rotation of the deflection roller 2 is indicated by the arrow in the cross section of the roller.
- the rotary driven scoop roller is designated, which is largely immersed in the zinc trough 4 and whose direction of rotation is also indicated by an arrow.
- the zinc trough 4 has a height-adjustable weir, which is indicated at 5. By means of this weir, the level of the zinc in the zinc trough 4 can be adjusted so that the depth of immersion of the scoop roller 3 in the zinc bath of the zinc trough 4 can be varied.
- the zinc pump 6 designates the zinc pump, with the aid of which the liquid zinc can be pumped from the zinc tub 7 located below the zinc tub 4 into the zinc tub 4.
- the zinc tub 7 is the zinc kettle into which the continuous strip is immersed, even when the strip is coated on both sides.
- the nozzle knife is designated, with whose gas jet the thickness of the not yet solidified zinc layer can be adjusted by stripping off the excess zinc.
- a device is provided at 9 with which crystallization nuclei (zinc dust) can be applied to the freshly coated strip, as a result of which a particularly uniform surface can be achieved. Since the entire device is arranged in the protective gas housing shown in FIG. 1, a protective gas lock must be provided at the exit of the strip from this housing, which ensures a seal against the normal atmosphere.
- Fig. 2 the same parts are labeled the same.
- the guide plate is indicated at 12, with the aid of which liquid zinc 11 can be conducted into the gap between the deflection roller 2 and the scoop roller 3, which is previously pumped from the zinc trough 4 onto the guide plate 12 by means of the zinc pump 13.
- the supply of liquid zinc in the gap between the deflection roller and scoop roller can be improved, so that the uniformity of the coating is optimized.
- the belt to be coated running in the direction of the arrow around the deflection roller 2 is not touched by the outer surface of the scoop roller 3, but the gap between the belt surface and the scoop roller jacket is extremely small.
- the gap serves only for the contact-free rotation of the scoop roller 3, which, as the arrows indicate, rotates in the opposite direction to the deflection roller 2.
- the scoop roller 3 is immersed with the largest part of its circumference in the zinc bath of the zinc trough 4, when the driven scoop roller 3 is rotated, liquid zinc is carried along by adhesion to the surface of the scoop roller 3 and in the vicinity of the gap between the scoop roller 3 and the deflection roller 2 or the band B carried over it.
- the surface of the strip B is wetted with the liquid zinc, which adheres to the surface in a certain layer thickness and is carried along as a coating.
- the particularly favorable coating results from the fact that the belt B runs in the opposite direction to the scoop roller 3 and a constant amount of zinc is always pressed in the gap between the two rollers. This results in an even better effect than when the strip is passed through a zinc bath, because the strip is not only wetted by the "offered" liquid coating medium but also generates the described flow against the strip surface by the counter-rotating scoop roller.
- the additionally provided device for guiding the liquid zinc 11 with the aid of the guide plate 12 only serves to improve the zinc supply in the gap.
