  • the invention relates to a method for Production of such a sheet.
  • the zinc coating is thereby usually applied in strip finishing plants.
  • To hot dip galvanizing is suitable, in which the Steel tape in baths made of zinc or zinc alloys a temperature between 440 ° C and 465 ° C is immersed.
  • the zinc coating can also be electrolytic be deposited on the steel material.
  • the steel sheets can be immersed in a zinc or zinc alloy bath to anneal a to get particularly resilient zinc coating ( "Galvanealing").
  • the phosphating solutions can contain zinc, manganese and nickel ions in addition to the required phosphate ion (PO 4 ) contents.
  • Such phosphating solutions containing zinc, manganese and nickel ions are also referred to in technical terms as "trication-phosphating solution” (DE 197 56 735 A1).
  • the phosphating can be carried out piece by piece after the forming of the processed steel sheet and before painting. However, it is also possible to apply the phosphate coating in high-speed belt treatment plants.
  • An essential parameter of the success control is the weight of the coating recorded per unit area. For sheet metal processed in automobile construction, this is usually 0.8 g / m 2 to 4 g / m 2 , layer weights of 1 g / m 2 to 2 g / m 2 being preferred in the prior art.
  • a layer weight of 1 g / m 2 corresponds to a phosphorus content (Sg p ) of 140 mg / m 2 in this layer.
  • phosphated sheets not only have improved painting properties, but can also be shaped particularly well. So is for example in EP 0 489 105 B1 (DE 690 10 207 T) a process for deep drawing metal sheets has been proposed according to the prior to deep drawing a salt of the sheet metal or the deep-drawing tool Alkali metal such as Li, Na or K, and one related to the metal forming the sheet chemically inert anions, selected from the group of phosphates, deposited the deposition of the salt by application an aqueous solution.
  • the salt should on the Tool in deep drawing by reaction with one Deep drawing oil form a soap through which the friction between tool and workpiece is significantly reduced.
  • the object of the invention was one for Forming into a component, especially for the Deep drawing to create particularly suitable steel sheet, which is easy to paint and also with high degrees of forming in the forming tool the risk of Cracking and similar component defects is minimized.
  • a procedure should be specified with which such sheets are made in a simple manner can be.
  • This object is achieved in relation to the product by a sheet metal produced from a steel material, which is intended for the production of steel components by forming, in particular deep drawing, and is covered with a phosphate layer, the phosphorus content of which is at most 0.05 g / m 2 P. ,
  • the above-mentioned object is achieved in that, in the production of a galvanized steel strip provided with a phosphate coating, the steel strip is first provided with a zinc coating in a strip galvanizing plant and that a phosphate layer is then applied to the galvanized steel strip, the phosphorus content of which is at most Is 0.05 g / m 2 .
  • According to the invention is to be deformed Steel sheet applied a layer of phosphate, the one very small thickness and a correspondingly small Maximum phosphorus content of 50 mg P per square meter having.
  • sheets can be used a thin layer of phosphate much better than Deform phosphate-free sheets in a forming tool and can be compared with sheets that are known in the Has been covered with larger phosphate layer thicknesses are. This is particularly evident in deep-drawing operations with high degrees of deformation that when in use Sheet metal coated according to the invention is a clear one Reduction of friction between tool and sheet established. This reduction in friction allows such Sheets, the deformability itself because of the conventional procedure in the forming tool occurring voltages is limited beyond these limits to deform out.
  • the invention proves to be particularly favorable in such cases Sheets in which the phosphate layer on one on the Steel material trained zinc layer is applied.
  • the success of the invention is independent of the type and how the zinc coating is applied. So the zinc layer can be used in sheets according to the invention Generate electrolytically or by hot-dip galvanizing. As well it is possible to hot dip galvanize with subsequent annealing (galvanealing). The In this case, annealing is carried out in a known manner above the melting point of zinc Temperatures. This from the combination of Dip galvanizing and annealing formed the galvanizing process is also known as "galvanealing" designated. It leads to a zinc coating, which in It consists essentially only of iron-zinc compounds and good adhesion with particularly good Formability distinguishes.
  • the phosphate layer also on sheets according to the invention one-sided on only one of the belt surfaces or on both sides on the top and on the Bottom of the sheet to be applied.
  • the method according to the invention can be particularly effective perform economically by the individual Work steps carried out in a production line become. With such an "inline" successive Implementation of the various coating steps stands at high when leaving the production line Throughput a product is available which immediately afterwards to form a sheet metal component leaves.
  • the invention phosphate coated tape before it is deformed with a Oil sprayed to reduce friction during the To further reduce the deformation process.
  • the dilute phosphating solution used to produce the thin phosphate layer which according to the invention is kept thin and limited to a phosphorus content of 0.05 g / m 2 , can be sprayed onto the steel strip to be coated.
  • practical tests have shown that particularly good coating results are obtained if the applied volume flow is dimensioned such that the surface of the steel strip to be coated is completely rinsed with phosphate solution.
  • the phosphate coating produced according to the invention also if the phosphate solution in addition to zinc ions additional Contains cations. So there is the received Phosphate layer when Mn and Ni ions are added to the for the coating not only used phosphate solution Zinc based Hopeit, but it also contains Ni and Mn-modified hop components.
  • the manganese content causes the formation of small, densely packed Crystals leading to increased alkali resistance lead and thus improve the corrosion protection.
  • nickel promotes the formation of a thin one Phosphate layer and increases the infiltration and Stone chip resistance on the phosphate layer applied paint.

  • an activation solution are aqueous dispersions of Titanium orthophosphates based on sodium phosphates used.
  • the purpose of applying the activation solution is targeted crystallization nuclei on the strip surface multiply. This way the number of crystals per unit area increased and, accordingly, the Crystal size and the layer weight reduced. About that In addition, the crystallization nuclei cause that in the subsequently carried out small phosphating Zinc phosphate crystals are formed. little one Zinc phosphate crystals prove to be cheap because they are when forming the steel strip into components also under high effective forming forces the risk of tearing the Reduce the phosphate layer.
  • the steel strip S After activation, the steel strip S enters the phosphate rinsing device 4. Rinsing nozzles, not shown here, are installed therein, via which the phosphating solution is rinsed onto the surfaces of the steel strip S to be coated.
  • the phosphating solution used for this purpose is a solution known per se under the trade name "Granodine 5854 E10", but is very dilute for carrying out the process according to the invention. This solution is composed according to the "tri-cation system” and contains not only zinc ions but also Ni and Mg ions in order to ensure optimized usage properties of the phosphate layer applied to the belt surfaces. The dilution of the phosphating solution is chosen so that the phosphate coatings produced on the surfaces of the steel strip S have a maximum phosphorus content of 10 mg / m 2 .
