Definitions

  • the invention relates to a liquid lubricant for the cold forming of metallic materials and its production, which is used, for example, in cold rolling, cold upsetting, thread rolling, drawing sheet metal parts, calibrating sintered bodies, stranding and bending, and in particular when drawing strand-like shaped material such as wire, profiles and Pipes, is advantageously applicable.
  • a lubricant When pulling wires, profiles, pipes, etc. a lubricant must be applied to the drawing material before the drawing tool, which is to prevent direct contact between the working surfaces of the drawing tool and the surface of the drawing material.
  • the use of solid, semi-solid or liquid lubricants at room temperature is common.
  • the liquid lubricants used include Oils, chlorinated paraffins, soap solutions and reactive fatty acid soaps are used in conjunction with a basic chemical coating.
  • Liquid lubricants are also known which consist of solid lubricants dispersed in water. In one of these lubricants, alkaline earth metal soaps are used as solid lubricants.
  • the lubricant also contains 2% by mass of polyvinyl alcohol as a dispersant for the solid lubricant, a corrosion inhibitor and surface-active substances. The lubricant is applied to the material to be formed, for example in the immersion process, and then dried, a solid lubricant film being produced for the subsequent forming process.
  • a disadvantage of this lubricant is that the dried solid lubricant film experiences a significant reduction in quality due to the thermal degradation of the polyvinyl alcohol that occurs during the shaping process, in particular with regard to its dynamic viscosity, its temperature resistance and its adhesiveness. Due to this reduction in quality, large cross-sectional reductions per train or only small total cross-sectional decreases per lubricant application are possible. In addition, this lubricant allows only low drawing speeds due to thermal degradation, and the forming of difficult-to-form materials is also critical.
  • these lubricants may also contain inorganic water-soluble salts, such as fatty acid salts, alkali phosphates, alkali borates and ammonium salts.
  • inorganic water-soluble salts such as fatty acid salts, alkali phosphates, alkali borates and ammonium salts.
  • the lignin compounds contained serve as dispersants and solubilizers for the present metal soaps.
  • the modified polyvinyl alcohols are, for example, phosphatically esterified or carboxy-modified polyvinyl alcohols, for example the ammonium salts of corresponding phosphate esters or corresponding carboxylates.
  • the alkaline earth metal soap is used as an aqueous dispersion which is prepared by dispersing the soap in water using at least one anion-active compound and / or nonionic surface-active compound.
  • the invention is based on the object of specifying a liquid lubricant which gives high-performance liquid or solid lubricating coatings on metal material to be formed, and a method for its production.
  • the object is achieved according to claims 1 and 7.
  • the dependent claims relate to advantageous embodiments.
  • both types of polyvinyl alcohols E and F preferably have a degree of polymerization in the range from 100 to 1500, the total content of polyvinyl alcohols E and F being ⁇ 3% by mass if both types are present.
  • water-insoluble fatty acid salts A are preferred Alkaline earth metal soaps and preferably technical calcium stearate are present in an amount of 3 to 8% by mass.
  • the water-soluble alkali metal soaps B advantageously contain sodium soaps, preferably technical sodium stearate.
  • Suitable glass-forming borate C are e.g. Alkali borates and preferably borax.
  • Suitable surfactants D are in particular anionic and nonionic surfactants and in particular polyethylene oxide adducts, preferably nonylphenol-polyethylene oxide adducts.
  • hydrogen peroxide oxygen, ozone, peroxides, peroxo salts, hypochlorites, chlorates, dichromates and / or permanganate
  • the preferred oxidizing agent is hydrogen peroxide.
  • the oxidizing agent is reacted with an acidic polyvinyl alcohol solution, preferably with a pH of 1.5 to 4.
  • the oxidizing agent can also be reacted with an alkaline polyvinyl alcohol solution, preferably with a pH of 8 to 12.5.
  • the oxidizing agent is first reacted with an acidic polyvinyl alcohol solution, whereupon the pH is shifted to the alkaline range during the reaction by adding alkali metal hydroxides, preferably sodium hydroxide.
  • the lubricant according to the invention has a low to high viscosity and guarantees a high coating mass and a homogeneous and thermally stable lubricant layer on the material to be formed. This enables high individual degrees of forming and forming speeds to be achieved, and the forming of difficult-to-form materials is also possible. In addition, intermediate coatings between individual forming stages can be largely avoided. If the lubricant contains structure-modified polyvinyl alcohol, there is no or only a slight tendency to form skin or gel, which has a particularly favorable effect on the coating and drying effort.
  • aqueous polyvinyl alcohol solution which contains a polyvinyl alcohol which is 2% esterified with acetate groups and which has a pH of 2.2 and a temperature of 93 ° C.
  • Hydrogen peroxide added as an oxidizing agent.
  • the solution is made alkaline with sodium hydroxide, the oxidation reaction is continued for a further 10 minutes while maintaining the specified temperature, and then an aqueous calcium soap dispersion which contains an alkylphenol-polyethylene oxide adduct as a dispersant is mixed in to prepare a lubricant concentrate.
  • This concentrate is diluted with water before use for cold forming and sodium stearate is added at a temperature of 80 ° C.
  • the ready-to-use lubricant is made from the following composition: (Dimensions-%) Structure modified polyvinyl alcohol 1.8 Calcium soap 6 Alkylphenol polyethylene oxide adduct 0.3 Sodium stearate 1 borax 5 water Rest.
  • This lubricant is used to coat 6.5 mm thick Mn 6 wire rod in a coil immersion process at 80 ° C. After drying the lubricant, which takes place in a very short time due to the inherent heat of the wire, the wire is removed in 7 steps with a pulling speed of 10 m / s on the 7th block without intermediate coating drawn to a final diameter of 2.0 mm.
  • This lubricant is used to coat 8.0 mm thick wire rod of 20 Mn B 4 Q quality in a coil immersion process at 75 ° C. After the lubricant has dried, which occurs quickly due to the inherent heat of the wire, the wire is pulled to 7.05 mm in one go. After drawing, the wire has a residual lubricant film that is sufficiently thick for further processing, for example by cold upsetting.
  • the finished lubricant is made from the following composition: (Dimensions-%) Structure modified polyvinyl alcohol 1.4 Calcium soap 6 Alkylphenol polyethylene oxide adduct 0.3 Sodium metaborate 4th Manganese dioxide hydrate 0.02 water Rest.
  • This lubricant is used to coat 5.5 mm thick wire rod of quality 10 Mn Si 6 in a coil immersion process at 85 ° C and to dry it in air. Then the coated wire is drawn in 5 steps without intermediate coating to a final diameter of 2.5 mm.
  • a lubricant is made from the following composition: (Dimensions-%) Calcium stearate 5 Sodium tetraborate decahydrate 5 Polyvinyl alcohol 1.5 water Rest.
  • the polyvinyl alcohol used is esterified to 12% with acetate groups.
  • This lubricant is used to coat 6.5 mm thick wire rod of quality C15 in a continuous process.
  • the lubricant layer is then dried and then the wire is drawn to 3.6 mm in 6 steps at a pulling speed of 7 m / s.
  • a lubricant is made from the following composition: (Dimensions-%) Calcium stearate 4th Sodium metaborate 6 Polyvinyl alcohol 1 water Rest.
  • the lubricant film is dried and the wire is pulled at a pulling speed of 6 m / s in one go to 2.0 mm in diameter.
  • a lubricant is made from the following composition: (Dimensions-%) Calcium stearate 4th Sodium metaborate 2.5 Polyvinyl alcohol 1 water Rest.
  • the polyvinyl alcohol used is 2% esterified with acetate groups.
  • a steel wire of quality C 15 Q with an initial diameter of 3.35 mm is drawn to 3.0 mm in one single step in a wet pass.
