Definitions

  • the present invention relates to an aluminium and aluminium alloys cold rolling oil composition and to a process of cold rolling aluminium and aluminium alloy sheets.
  • 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, they also 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 final aluminium sheet may be used to wrap food articles or may come in contact with food, it is necessary that any composition used in the rolling process complies with the legal specifications relating to the food industry.
  • the final aluminium sheets must not be stained by the compositions used in the rolling process.
  • the invention thus provides an oil composition for aluminium and aluminium alloys cold rolling mills that 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
  • Z-high type e.g. 2-high, 4-high, 6-high
  • the invention is specially designed for aluminium and aluminium alloys for 2-high, 4-high and 6-high mills.
  • the invention provides improved aluminium or aluminium alloy strip surface finish by minimizing the sticking tendency after thermal treatment of the rolled coils and excellent rolling capabilities by reducing the rolling force and mill power required when rolling harder copper alloys.
  • the International application n° WO 98/04657 relates to a process for cold-rolling aluminium comprising the provision on the surface of the aluminium of an organic lubricant which is selected from (i) an iso-paraffin hydrocarbon mixture, (ii) a mixture of iso-paraffinic and naphthenic hydrocarbons and (iii) a mixture of (i) and (ii).
  • an organic lubricant which is selected from (i) an iso-paraffin hydrocarbon mixture, (ii) a mixture of iso-paraffinic and naphthenic hydrocarbons and (iii) a mixture of (i) and (ii).
  • the invention provides a aluminium and aluminium alloys cold rolling oil composition
  • a base stock oil and, based on the total weight of the composition, from 0.01 to 5% by weight of a coumpound A having the formula X 3 -PO 3 , wherein
  • alkyl groups can be linear or branched.
  • alkyl groups include the propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, palmityl, stearyl and dodecanyl groups.
  • aryl groups include phenyl, naphtyl, anthracenyl, indenyl and thienyl groups. Among these groups phenyl is preferred.
  • the alkyl and aryl groups include no heteroatom and are unsubstitued.

  • the invention provides the use of the oil composition of the invention in aluminium and aluminium alloys cold rolling process.
  • the oil compositions of the invention are neat oils.
  • the base stock oil is any oil typically used in the field of cold 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.
  • very low viscosity base stocks have been developped for high speed cold rolling mills.
  • Light petroleum fractions such as kerosene cut base oils are suitable for these applications.
  • the kerosene type base stock is hydrotreated to improve its resistance to oxidation and to meet the non staining requirements during annealing and thermal degreasing.
  • These base stocks are highly saturated paraffinic fractions that have been extracted sulphur, nitrogen, oxygen, heteroatoms that are naturally present in petroleum cuts.
  • the mineral oils and additives used in the invention are preferably those which can be safely used as a component of nonfood articles intended for use in contact with food. These oils and additives are described in 21 CFR Ch. 1 ⁇ 178.3620 (a), (b) and (c) and 21 CFR Ch.1 ⁇ 178.3910 of the Food and Drug Administration, HHS.
  • the base oil typically has a viscosity from 1.2 to 6.0 cSt at 40°C and preferably from 1.6 to 3.0 cSt at 40°C. Viscosity can be adjusted by using a viscosity adjuster (such as kerosene), if needed.
  • a viscosity adjuster such as kerosene

  • anti-rust agents are amine derivative of alkenyl succinic anhydride.
  • friction reducing agents or lubricity agents are fatty alcohols having a carbon number in the range from 12 to 18, fatty esters having a carbon number in the range from 12 to 18, like glycerol monooleate.
  • the aluminium alloys to which the invention applies are any alloys, including 1000, 2000, 3000, 5000, 6000, 7000 series.
  • the oil composition of the invention can also be used in another non ferrous metals cold rolling process.

  • the oil temperature is generally maintained at a temperature below 70°C, preferably below 40°C.
  • the process can be carried out on any rolling mill, such as of a 2 high, 4high, 6 high mill, in tandem, etc.
  • the instant oil composition allows a significant reduction of the number of passes. With conventional prior art oils, the number of passes was typically 5.
  • the oil composition of the invention allows lowering this number to 4 passes, which is a significant gain.
  • composition is prepared: Ingredients Content (wt%) Kerosene type base oil, aromatic free, high paraffin content, 1.7 cSt at 40°C 95.6 Lauryl alcohol 1.0 N-butyl stearate ester 3.0 Oleic acid 0.1 Tri(nonyl-phenyl)phosphite (TNPP) 0.3
