- the galvanizing of steel body panels for the purpose of corrosion protection has largely prevailed in the last decades.
- the galvanized steel plates in the hot dip process or by means of electrolytic deposition are characterized by a good adhesion of the zinc layer to the steel sheet / and a good processability, in particular Umformbarköit from.
- DE 100 39 375 A1 describes a process for producing a corrosion-protected steel sheet, in which a layer of metals, in particular alkaline earth metals, magnesium or aluminum or their alloys, in a continuous steel sheet provided with a zinc or zinc alloy coating
- this heat treatment which consists of a heating and a holding phase, it comes in the areas of the surface in which in the vacuum coating multiphase alloys between the vapor-deposited layer and the zinc or zinc alloy layer with a melting temperature lower than that of the zinc or zinc alloy layer, locally to the welds, in which case the vapor-deposited metal or vapor-deposited alloy also penetrates into deeper layers of the zinc coating heat treatment is the steel sheet in cooled an unchanged oxygen-poor atmosphere, the fusions solidify.
- the corrosion resistance of the galvanized steel sheet is positively influenced by the dissolution of the Zinküberzmgs is slowed down by the stabilizing effect of the vapor deposited and penetrated by the melts ia the zinc coating metal greatly.
- DE 195 27 515 C1 describes another method for producing a corrosion-protected steel sheet.
- one or more of Zirxk different metals, in particular Fe, Mn, Cu, Ni and Mg, or their alloys by vacuum coating applied to a provided with a zinciferous steel sheet and then without intermediate exposure to oxidizing atmosphere of a thermal
- the invention is therefore based on the object of specifying a method for producing a corrosion-protected steel sheet for coating with an organic coating agent, which in comparison to the generic state of the art by excellent adhesion of the organic coating composition and by a high corrosion resistance in the coated state of the sheet distinguished.
- the object is achieved by a method according to the preamble of claim 1, characterized in that the cooling is carried out with an aqueous cooling medium under normal atmospheric conditions.
- a steel sheet is first provided in a known manner with a coating of zinc or a Zinklegieri ⁇ ng. This takes place in a known manner in the melt-dip process (hot-dip galvanizing) or by electrolytic deposition.
- the galvanized steel sheet is coated in vacuum with an additional metal.
- a thermal diffusion treatment in which atoms of the metal layer applied in a vacuum diffuse into the underlying zinc or zinc alloy. Due to the residual gas content in the vacuum and during the thermal diffusion treatment, a native oxide layer forms on the surface of the coated steel sheet, which passivates the surface and thus increases its corrosion resistance.
- the "finished steel sheet after the thermal diffusion treatment is cooled with an aqueous cooling medium.
- Another advantage of cooling by means of an aqueous cooling medium is that in subregions of the coated surface, in which no native oxide layer is formed, ie where the bare metallic coating is exposed, water molecules are decomposed from the coolant, with anti-corrosive, partially form sparingly soluble hydroxides. These hydroxides or: the resulting oxides in the subsequent drying improve significantly the adhesion of organic coatings on the surface of the steel sheet.
- the applied in vacuum on the galvanized sheet surface layer may be composed of one or more metals.
- those metals are used which form mixed phases with the zinc of the zinc or zinc alloy layer. This results in a good connection of both layers, and the corrosion resistance is increased.
- Particularly suitable are reactive metals, such as magnesium, aluminum, iron or manganese or their alloys.
- a predetermined temperature control in the sense of a defined starting temperature of the finished steel sheet zi ⁇ onset of cooling, a preset temperature of the cooling medium and a specified cooling time sowor ⁇ l shortening the treatment time and the quality of the corrosion protection layer can be improved in terms of higher corrosion resistance.
- the starting temperature of the steel sheet at the beginning of Abkühlumg is preferably 250 to 35O 0 C, in particular 290 to 310 0 C.
- the setting of the starting temperature can technically! done in different ways.
- the use of cooling rolls is just as possible as the use of gas cooling.
- the duration of the cooling is preferably 1 to LO s.
- the temperature of the cooling medium should not be set too high, since in this case the metal coating of the steel sheet by the coolant is strong is attacked.
- the temperature of the coolant should not exceed 42 ° C.
- the final temperature of the steel sheet after cooling is preferably 20 b> is 120 0 C, in particular 40 to 60 0 C. This results in a wide working range. An increase in the final temperature beyond 12O 0 C addition does not make sense, otherwise it can lead to damage of subsequent rubberized rollers for the removal of the cooling medium.
- the cooling can be carried out in a dip.
- the coated steel sheet can also be sprayed, wherein the spraying is preferably carried out under high pressure, since in this case a particularly rapid cooling and Passivierrung the surface can be achieved.
- hot sheet metal surfaces in this way are formed directly on the OberfLowne forming Wasserschampfschichit which greatly reduces the heat transfer between the steel sheet and the cooling medium (Leidenfrost effect).
- aqueous cooling medium should be removed immediately after cooling from the surface of the coated steel sheet.
- the removal of the cooling medium can be done by squeezing or durrch a gas jet.
- the corrosion resistance and the adhesion of the organic coating to be applied can be further improved by further measures.
- soluble salts can be added to the aqueous cooling medium. These set free suitable divalent metal ions or hydroxide ions and thus shift the solution equilibrium to the undissociated oxide according to the equation
- buffering substances in particular acetate, phosphate, borate, carbonate, or citrate ions, can be added to the aqueous cooling medium, by means of which an optimum pH in the sense of minimum hydrolysis of amphoteric native metal oxides can be set.
- the pH value should be neither in the weakly acidic range (pH ⁇ 5) nor in the strongly basic range (pH> 12.5).
- the drawing shows a plant for the continuous refining and subsequent painting of a steel strip.
- a substrate in the form of a steel strip 1 is first passed through one or more cells 2 and coated in a electrolytic deposition process with a zinc layer.
- galvanizing in the hot dip process is possible.
- the steel strip 1 enters a Vakuumkanxmer 3 a.
- the band 1 with one from the state coating technique known in the art, for example by means of PVD, with an additional metal, preferably magnesium coated.
- additional metal preferably magnesium coated.
- Further usable metals are, for example, aluminum and manganese.
- the coated galvanized steel strip 1 After leaving the vacuum chamber 3, the coated galvanized steel strip 1 enters a heating chamber 4 provided with a heating device 4a. In this heating chamber 4 then takes place a thermal diffusion treatment, which can be carried out in a normal atmosphere. In the course of the diffusion treatment, the magnesium layer applied in a vacuum partially diffuses into the underlying zinc layer, forming intermetallic phases consisting of zinc and magnesium.
- the steel strip 1 After emerging from the heating chamber 4, the steel strip 1 is deflected at least one cooling roller 5 and is thereby cooled to a defined temperature. This is at the same time the starting temperature of the subsequent cooling process and is preferably 250 to 350 0 C, in particular 290 to 31O 0 C.
- the steel strip 1 is passed into a further chamber 6.
- the diffusion-treated surface with an aqueous Spray cooling medium under high pressure.
- the cooling can also take place in a dipping bath.
- the aqueous cooling medium may be pure Wasserr act.
- salts which shift the solution equilibrium to the undissociated oxide can also be dissolved in the cooling medium.
- the cooling medium can contain buffering substances, for example acetate, phosphate, borate, carbonate, or citrate ions, by means of which an optimum pH value can be set in the sense of minimal hydrolysis of magnetic native metallic oxides.
- the spraying device is designed such that the coated steel sheet is completely wetted immediately at the beginning of the cooling by the aqueous cooling medium in order to avoid the formation of visible patterns on the surface.
- the cooling in the chamber 6 takes place with a predetermined temperature control. Daloei is the temperature of the cooling medium maximum 42 0 C-
- the exposure time of the cooling medium to the steel strip 1 is between 1 and 10 s.
- the cooling medium is removed by squeezing rollers 7 from the Bandoberiflache.
