Definitions

  • the present invention relates to a water-soluble copper, copper alloys and non-ferrous metals intermediate cold and hot rolling composition and to a process for intermediate cold or hot rolling copper, copper alloys and non-ferrous metals.
  • the copper, copper alloys and non-ferrous metals rolling industry expresses the need to maximize the efficiency of their 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 rolling mills that enables to prepare emulsions which affords the following customer benefits:
  • the invention is effective on any type of rolling, be it reversible or not, on breakdown, intermediate and finishing mills.
  • the invention exhibits high reduction and rolling capabilities while providing an excellent strip surface finish when rolling at high speed.
  • the invention provides a water-soluble copper, copper alloys and non-ferrous metals rolling oil composition
  • a water-soluble copper, copper alloys and non-ferrous metals rolling oil composition comprising a base stock oil and, based on the total weight of the composition
  • intermediate cold is herein meant that the temperature is the ambiant temperature for the copper and copper alloy ingot.
  • hot rolling is herein meant that the temperature is around 750°C for the copper and copper alloy ingot.
  • the oil composition further comprises, based on the total weight of the composition, from 0,1 to 20% of a mixture of ethoxylated alcohols (having from 5 to 15 carbons atoms and preferably from 12 to 15 carbon atoms).

  • the base stock oil is any oil typically used in the field of intermediate cold or hot rolling. It can be paraffinic or naphthenic.
  • Paraffinic base oils are made from crude oils that have relatively high alkane contents (high paraffin and isoparaffin contents). Typical crudes are from the Middle East, North Sea, US mid-continent. The manufacturing process requires aromatics removal (usually by solvent extraction) and dewaxing. Paraffinic base oils are characterized by their good viscosity/temperature characteristics, i.e. high viscosity index, adequate low-temperature properties and good stability. They are often referred to as solvent neutrals, where solvent means that the base oil has been solvent-refined and neutral means that the oil is of neutral pH. An alternative designation is high viscosity index (HVI) base oil. They are available in full range of viscosities, from light spindle oils tc viscous brightstock.
  • HVI high viscosity index

  • the water-soluble oil composition of the invention is prepared by blending the base oil and the other ingredients under stirring or with any mixing device, preferably whilst controlling the temperature so that is does not exceed 50°C, and more preferably 35°C.
  • An oil-in-water emulsion is prepared by diluting under stirring the oil composition of the invention in water.
  • An interesting feature of the invention is that it is possible to use hard water having up to 200 mg calcium carbonate per liter.

  • the cold intermediate rolling process can be the classical process. It is generally carried out at ambient temperature.
  • the rolling process is preferably carried out on breakdown or finishing mills.
  • the instant oil-in-water composition allows a significant reduction of the number of passes. With conventional prior art emulsions, the number of passes was typically 3-10. The emulsion of the invention allows lowering this number by 1 pass, which is a significant improvement.
