Definitions

  • the instant invention concerns a lubricating agent, viz. a forming oil, on synthetic basis, free from mineral oils, dispersed in an aqueous vehicle, having high lubricity and protective characteristics, particularly indicated for forming operations, even extreme ones. More particularly, the instant invention concerns a forming oil, on synthetic basis, free from mineral oils, formulated in the form of a hydroalcoholic dispersion, which can be applied by spraying, rolling or immersion, or by any other convenient method, be it directly on coils, at the exit of the production lines provided with a coating-drying section (at a temperature of approx.60°C) before the winding of the coil, or in the forming department.

  • the instant invention concerns a forming oil, on synthetic basis, free from mineral oils, formulated in the form of
  • the sheet steel is further lubricated, off-press (manually or automatically) or in the press, with more viscous oils having higher lubricity.
  • synthetic forming oils were developed, mainly on the basis of acrylic polymers, in a solvent medium, or dispersed in an aqueous medium, which after drying or thermal curing yield solid films on the metal surface; such synthetic forming oils, when applied in an amount of 3-4 g/m2, develop lubricities comparable or superior to the best oil lubricants.
  • coated sheet steel especially electro-galvanized sheet steel, which involves more problems in the forming step (higher degree of friction, formation of dirt deposits and pittings)as well as greater attention to industrial hygiene problems and to the disposal of industrial wastes, make the necessity of replacing mineral oils by more effective and less polluting lubricating materials a more relevant issue.
  • the use of the inventive lubricating material allows to considerably reduce manufacturing wastes and to use cheaper sheet steel, i.e. having lower forming characteristics.
  • the cost impact of the synthetic forming oil is instead linked to the minimum effective thickness for achieving lubrication, as it can be taken from the histogram in Fig.1.
  • the inventive lubricating material because of its particular adjuvants and coatability, allows to obtain an excellent protection even of the formed parts having mechanically severely stressed zones. In an accelerated corrosion test with formed articles kept in a climatic chamber for one month at 40°C, with 85% relative humidity (R.H.), no red-rust focuses are detectable.
  • the inventive forming oil exhibits superior (approx. double)lubricity vis-à-vis the mineral oil materials already at coating weights of 1 g/m2.
  • the lubricity increases further in asymptotic manner at coating weights of 2-3 g/m2.
  • the lubricity characteristics are excellent be it under prevailing dishing working conditions,be it under mixed conditions (viz. dishing, drawing, plane strain).
