Definitions

  • the method according to the invention which is applied to the cold rolling of sheets or strips of A1 or its alloys and which makes it possible to eliminate such defects therefore consists of a pre-lubrication of the product before rolling using a whole oil mineral and / or synthetic, optionally additive and into a lubrication of the product and of the tools during rolling with the aid of water or an aqueous lubricant.
  • the pre-lubrication of the product before its cold rolling can result either from a specific operation, or be the result of a previous operation, the product obtained not being "degreased".
  • this operation is carried out, discontinuously or continuously, on the cold rolling line using any known device, such as spray bars (with or without air), electrostatic device, wetted wiper. of oil, etc.
  • any known device such as spray bars (with or without air), electrostatic device, wetted wiper. of oil, etc.
  • the uniformity and regularity of the thickness of the layer of lubricant deposited, as well as its adhesion to the product, can be improved by known systems of brushes, felts, pinch rollers, etc. ..
  • the lubrication of the cold rolling operation is ensured by an emulsion or a solution of oil in water or even water alone, possibly additive.
  • laminated strips free from surface defects, can be obtained from strips in the annealed (O) or in the strain-hardened state (H) with reduction rates ranging from 50 to 90% in one single pass and at rolling speeds ranging from 500 to 1000 m / min, for thicknesses generally between 15 and 0.15 mm.
  • Pre-lubrication was carried out by depositing a mixture of mineral oil and synthetic oil (50% - 50% by weight) at the rate of a few grams / m 2 by spraying on both sides of the strip and spinning by pinch rollers.
  • the rolling itself was carried out on a quarto monocage rolling mill with lubrication by sprinkling using an aqueous emulsion at 10% by weight of oil:
