Definitions

  • the present invention relates to a hot rolling process for rolling aluminium and aluminium alloys sheets.
  • the invention also relates to a water-soluble aluminium and aluminium hot rolling oil composition, to a oil-in-water emulsion prepared therewith and to the use of said oil-in-water emulsion in a hot rolling process.
  • the aluminium and aluminium alloys 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 hot rolling mills that affords the following customer benefits:
  • the invention is effective on any type of hot rolling, be it reversible or not, on breakdown, tandem and combination mills.
  • the invention exhibits high reduction and rolling capabilities while providing an excellent strip surface finish when rolling at high speed.
  • FR-A-2 168 989 describes cold-rolling of aluminium using a composition which includes di(2-ethylhexyl) adipate ester.
  • the invention provides a hot rolling process for rolling aluminium and aluminium alloys sheets, comprising applying an effective amount of an oil-in-water emulsion comprising water and a water-soluble oil composition comprising a base stock oil and, based on the total weight of the water-soluble oil composition, from 1 to 80% and preferably from 3 to 30% by weight of di(2-ethylhexyl) adipate ester.
  • the oil composition further comprises, based on the total weight of the composition, from 0,05 to 20%, preferably from 0,1 to 5% by weight of a non-ionic surfactant, such as an ethylene oxide addition polymer.
  • a non-ionic surfactant such as an ethylene oxide addition polymer.
  • An example of such an ethylene oxide addition polymer is the ethylene oxide addition polymer sold by the company ICI under tradename Hypermer® A60.
  • the oil composition further comprises, based on the total weight of the composition, from 1 to 30%, preferably from 5 to 20% of oleic acid. It is actually believed that the free oleic acid provides a better surface finish to the aluminium or aluminium alloy strip.
  • the invention further provides a water-soluble aluminium and aluminium alloys hot rolling oil composition.
  • the invention further provides a process for preparing the water-soluble oil composition.
  • the invention further provides an oil-in-water emulsion containing the oil composition and a process for preparing this emulsion.
  • the invention provides the use of the water-soluble oil composition of the invention to prepare emulsions intended to be used in a aluminium or aluminium alloy hot rolling process.
  • the invention provides the use of the emulsion in a hot rolling process.
  • Figure 1 is a graph showing the applied rolling force versus the number of passes, first, when an emulsion of the prior art and then when an emulsion of the invention are used.
  • Figure 2 is a graph showing the applied net rolling power versus the number of passes, first, when an emulsion of the prior art and then when an emulsion of the invention are used.
  • the water-soluble 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 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 a mixture of paraffinic and naphthenic oils.
  • the base oil typically has a viscosity from 7 to 150 cSt at 40°C, and preferably from 20 to 50 cSt at 40°C.
  • the water-soluble oil composition preferably comprises a trialkanolamine (C 2-4 ), preferably triethanolamine, the amount of which being such that all bindable trialkanolamine is bound to a part only of the oleic acid.
  • the aim of this embodiment is to ensure that there remains free oleic acid in the oil composition.
  • the product of the reaction of the trialkanolamine with oleic acid acts as a surfactant.
  • the water-soluble 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.
  • 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 (
  • corrosion inhibitors or anti-oxidants are radical scavengers such as phenolic antioxidants (sterically hindered), aminic antioxidants, organo-copper salts, hydroperoxides decomposers, butylated hydroxytoluene.
  • radical scavengers such as phenolic antioxidants (sterically hindered), aminic antioxidants, organo-copper salts, hydroperoxides decomposers, butylated hydroxytoluene.
  • anti-rust agents are amine derivatives of alkenyl succinic anhydride.
  • friction reducing agents/lubricity agents are fatty acids (C 12 - 20 ) like lauric acid, oleic acid, palmitic acid, alkyl(C 6-10 ) alkylate(C 12-20 ) esters like di(2-ethyl-hexyl) adipate.
  • the oil composition is prepared by blending the base oil and the other ingredients, preferably under stirring or with any mixing device, 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. It is preferred to use 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 15%, by volume, of the oil composition.
  • the aluminium alloys to which the invention applies are any aluminum alloys, including 1000, 2000, 3000, 5000, 6000, 7000 series.
  • the hot rolling process can be the classical process.

  • the process is preferably carried out on a breakdown rolling mill, on a tandem rolling mill or on a finishing rolling mill.
  • the instant oil composition allows a significant reduction of the number of passes. With conventional prior art oils, the number of passes was typically 13.
