Definitions

  • Lubricants used in the hot forming of metals have long been known.
  • Such lubricants consist for example of mixtures of graphite and mineral oil. Such mixtures decompose at the usual application temperatures of 1100 to 1300 ° C and result in a strong environmental impact.
  • Lubricants used in the manufacture of seamless pipes for lubrication called Dome poles must meet special requirements and therefore exist made of graphite and mixtures of substances that provide these special properties. So describes DE-B-2 450 716 a high-temperature lubricant made from 10 to 90% graphite, 2 to 60% Alkylene polymer or copolymer, 0.2 to 8% suspension aid and 2 to 40% Film stabilizer.
  • EP-A-0 554 822 describes a lubricant which contains one or more graphite several clay minerals from the smectite class as well as polysaccharide and one non-ionic Contains surfactant.
  • EP-A-0 164 637 describes a high-temperature lubricant for non-cutting Hot forming of metals, 10 to 90% by weight graphite as a solid lubricant, 10 to 80% by weight contains inorganic additive and 0.2 to 4% by weight of organic stabilizing agent.
  • the inorganic Additive consists of 0.2 to 25% by weight boric acid, 0.2 to 98.8% by weight polyphosphate and 1 up to 99.6% by weight alkali silicate.
  • the lubricant is in the form of a 5 to 50% by weight dispersion applied.
  • the lubricants known to date contain organic and thus decomposable Substances and / or additives that the later wastewater, for example, by Strongly contaminate sludge formation and thus represent a major environmental burden.
  • the object underlying the invention was therefore a lubricant, in particular is usable as dome lubricant to get that in addition to graphite essentially contains as few organic substances as possible and the least possible harm to the environment regarding wastewater pollution.
  • this object is achieved with a lubricant with a content of 75 to 90 % By weight of graphite and 1 to 10% by weight of phosphates, which is characterized in that it as phosphates, a phosphate mixture of tetrasodium diphosphate, primary zinc orthophosphate, contains primary manganese orthophosphate, disodium dihydrogen diphosphate and potassium polyphosphate.
  • lubricants according to the invention do not contain any organic substances need to contain and preferably contain no organic substances at all, so that the graphite is the only decomposable component. So they preferably contain only inorganic Fabrics.
  • Graphite which has the main lubricating effect of such lubricants, exists Made of pure carbon, which is used at high application temperatures in an oxygen-containing environment burns, producing carbon dioxide, which creates a gas cushion on which in the first place the separation of tube and dome rod is based
  • the other ingredients in the lubricant have the task of creating an even lubricating film to produce a quick drying of the lubricating film and damage the Avoid mandrel rod or the inner surface of the pipe.
