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).
  • a mixture of ethoxylated alcohols sold by ICI under tradenames Synperonic® A7 and Hypermer® A60 can be used, the Synperonic® A7:Hypermer® A60 weight ratio preferably ranging from 1:10 to 10:1.
  • the invention further provides a process for preparing the oil composition.
  • the invention further provides an emulsion containing the oil composition and a process for preparing this emulsion.
  • the invention provides the use of the oil composition of the invention to prepare emulsions intended to be used in a copper, copper alloys and non-ferrous metals hot or cold intermediate rolling process.

  • the oil compositions of the invention are neat oil concentrates generally intended to be diluted in water to give oil-in-water emulsions.
  • 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 to viscous brightstock.
  • HVI high viscosity index
  • Naphthenic base oils have a naturally low pour point, are wax-free and have excellent solvent power. Solvent extraction and hydrotreatment can be used to reduce the polycyclic aromatic content.
  • a preferred base oil is an hydrotreated paraffinic neutral.
  • the base oil typically has a viscosity from 10 to 150 cSt at 40°C, preferably from 20 to 50 cSt at 40°C.
  • the fatty acid of the monoester has from 16 to 20 carbon atoms and preferably is oleic acid.
  • the polyol of the monoester is preferably glycerol.
  • the fatty acid of the tetraester has from 16 to 20 carbon atoms and preferably is oleic acid.
  • the azole derivative is generally selected from the group consisting of an aryltriazole, an arylimidazole and an arylthiazole.
  • Examples of an aryltriazole include benzotriazole, toluol triazole and toluyl triazole.
  • Examples of an arylimidazole include benzimidazole and 2-(5-aminopentyl) benzimidazole.
  • benzothiazole may be used.
  • Preferred azole is toluol triazole.
  • the oil composition may comprise classical additives, such as surfactants, coupling agents or cosurfactants, friction reducing agents or lubricity agents, corrosion inhibitors or anti-oxidants, extreme-pressure and anti-wear agents, bactericides and fungicides, anti-foaming agents, anti-rust agents.
  • classical additives such as surfactants, coupling agents or cosurfactants, friction reducing agents or lubricity agents, corrosion inhibitors or anti-oxidants, extreme-pressure and anti-wear agents, bactericides and fungicides, anti-foaming agents, anti-rust agents.
  • oil composition and therefore also the emulsion, do not comprise nonyl-phenol surfactants, which are considered to raise environment problems.
  • anti-foaming agents are silicone based, especially polydimethylsiloxane.
  • corrosion inhibitors are hindered phenols and zinc dialkyldithiophosphates (ZDDP).
  • extreme-pressure and anti-wear agents are dilauryl phosphate, didodecyl phosphite, trialkylphosphate such as tri(2-ethylhexyl)phosphate, tricresylphosphate (TCP), zinc dialkyl(or diaryl)dithiophosphates (ZDDP), phospho-sulphurized fatty oils, zinc dialkyldithiocarbamate), mercaptobenzothiazole, sulphurized fatty oils, sulphurized terpenes, sulphurized oleic acid, alkyl and aryl polysulphides, sulphurized sperm oil, sulphurized mineral oil, sulphur chloride treated fatty oils, chlornaphta xanthate, cetyl chloride, chlorinated paraffinic oils, chlorinated paraffin wax sulphides, chlorinated paraffin wax, and zinc dialkyl(or diaryl)dithiophosphates

  • radical scavengers such as phenolic antioxidants (sterically hindered), aminic antioxidants, organo-copper salts, hydroperoxides decomposers, butylated hydroxytoluene.
  • anti-rust agents are amine derivative of alkenyl succinic anhydride.
  • 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.
  • deionized water which may previously have been warmed to around 35°C.
  • the emulsion generally comprises water and, based on the total volume of the emulsion, from 0.5 to 30%, preferably from 1 to 20%, by volume, of the oil composition.
  • the copper alloys to which the invention applies are any copper alloy, including brass and bronze alloys.
  • non-ferrous metals to which the invention applies are nickel and nickel alloys, zinc and zinc alloys.
  • the hot rolling process can be the classical process. It is generally carried out at a temperature of ingot 750°C.
  • 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.
  • the emulsion preferably comprises, based on the total volume of the emulsion, from 2 to 3% by volume of the oil composition.
  • the emulsion preferably comprises, based on the total volume of the emulsion, from 4 to 7% by volume of the oil composition.
  • a composition is prepared by mixing the ingredients of Table 1 in the order in which they appear in this table. The temperature is maintained at a maximum of 50°C to ensure a complete dissolution and homogeneisation of the ingredients without impairing the properties of the emulsion.
