Definitions

  • the present invention relates to a water-soluble aluminium and aluminium alloys cold rolling oil composition and to a process for cold rolling aluminium and aluminium alloys.
  • the aluminium and aluminium alloys rolling industry expresses the need to maximize the efficiency of their cold rolled metal manufacturing process. In general terms, this means that there is a wish to operate at higher rolling speeds and to produce more marketable products per operating shift. Additionally, there is also a wish to minimize the number of passes through the mill taken to achieve a given level of reduction. Both these routes require that quality and surface finish be not compromised.
  • the invention thus provides an oil composition for cold rolling mills that enables to prepare emulsions which affords the following customer benefits:
  • the invention is effective on any type of cold rolling, be it reversible or not, of the Sendzimir type (e.g. 1-2, 1-2-3, 1-2-3-4), or of Z-high type (e.g. 2-high, 4-high, 6-high), be it a reversible mill, a tandem mill, etc..
  • Sendzimir type e.g. 1-2, 1-2-3, 1-2-3-4

  • white mineral oil it is herein intended very highly refined oils which consist entirely of saturated components, all aromatics having generally been removed by treatment with fuming sulphuric acid or by selective hydrogenation. Their name reflects the fact that they are virtually colourless and the most highly refined medicinal white oils are used in medical products and in the food industry.
