Definitions

  • the present invention relates to a water-soluble cold steel rolling oil composition and an oil-in water emulsion comprising water and the water-soluble cold steel rolling oil.
  • Cold steel rolling is a process which can be applied to steel sheets of about 0.5 to 1cm thick, which have been produced by a hot rolling process from thick (e.g. 20cm) slabs of hot steel, to further reduce the sheets to much lighter gauges of typically 0.15 to 0.35mm.
  • the cold steel rolling process is a balance of load applied through each series of rolls, front and back tension applied to the steel sheet and rolling speed though the rolls to achieve a steel sheet product of saleable quality.
  • the rolled steel is highly stressed during the cold rolling process and must be then relaxed to ensure that the steel is in the correct crystalline form for its designated application. Relaxation is achieved by an annealing process.
  • the surface quality of cold rolled annealed steel sheets can be marred by the presence of black staining and surface carbon residues.
  • Such steel sheet surface quality may not be suitable for use in automotive application areas where there is currently a designated maximum level of allowable surface carbon residues of 7mg/m 2 for mill clean sheet.
  • this sheet surface quality requirement appears to be in direct conflict with the pressures placed on mill owners to continually seek to run their mills at faster speeds to improve output, to reduce power consumption of the mill and to roll different and harder alloys of steel.
  • staining patches and surface carbon residues seem to be a function of the combination of the heat generated during the cold rolling process, contaminants in the cold rolling process and the composition of the rolling oil formulation.
  • a water-soluble rolling oil composition for use in cold steel rolling applications comprises 15 to 70 % by weight of a partial polyol ester having a hydroxyl value of between 20 and 50 mg KOH/g and a level of polyunsaturation of between 0.01 to 8% by weight.
  • polyunsaturation is defined so as to exclude monounsaturation.
  • the partial polyol ester may be derived from the reaction of at least one polyhydric alcohol with at least one monocarboxylic acid. Alternatively it may be derived from the blending together of at least two partial polyol esters or the blending together of a combination of at least one partial polyol ester and at least one fully esterified ester.
  • the polyhydric alcohol may be a diol, triol, tetraol and/or related dimers and trimers. Examples are neopentyl glycol, glycerol, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol, dipentaerthyritol and tripentaerythritol.
  • the polyhydric alcohol is chosen from neopentyl glycol, trimethyolpropane and pentaerythritol, especially trimethylolpropane.
  • the polyunsaturation in the partial polyol ester is derived from the at least one monocarboxylic acid.
  • the at least one monocarboxylic acid may be, for example, one or more polyunsaturated monocarboxylic acids or a mixture of polyunsaturated and non-polyunsaturated monocarboxylic acids.
  • the polyunsaturated or non-polyunsaturated monocarboxylic acid may have some monounsaturated carbon -carbon bonds and may have a linear and/or branched chain. It may be aliphatic or aromatic.
  • the polyunsaturated or non- polyunsaturated monocarboxylic fatty acid has 8-24 carbon atoms, more preferably 10-20 carbon atoms.
  • suitable polyunsaturated monocarboxylic fatty acids include those derived from coconut oil, topped coconut oil (coconut oil which has been further processed to remove the C8 and C10 saturated fatty acid components), palm kernel oil and mixtures thereof.
  • non- polyunsaturated monocarboxylic fatty acids examples include capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, hydrogenated C18 monomeric acid, arachidic acid, behenic acid and lignoceric acid and mixtures thereof.
  • Hydrogenated C18 monomeric acid is the C18 monomer by-product resulting from the dimerisation of oleic acid, which is then subsequently hydrogenated.
  • a specifically preferred partial polyol ester is derived from reaction of trimethyolpropane with a mixture of coconut oil or topped coconut oil and hydrogenated C18 monomeric acid.
  • the blend ratio of coconut oil or topped coconut oil to hydrogenated C18 monomeric acid in the partial ester composition preferably ranges from 80 to 20 weight percent to 20 to 80 weight percent, more preferably from 60 to 40 weight percent to 40 to 60 weight percent.
  • the partial polyol ester according to the invention is present at levels between 15 and 70% by weight, more preferably between 20 and 50%, even more preferably between 20 and 40% in the water-soluble rolling oil composition.
  • the partial polyol ester has a hydroxyl value of between 20 and 50 mg KOH/g, preferably between 25 and 40 mg KOH/g.
  • the partial polyol ester has a level of polyunsaturation of between 0.01 to 8% by weight, preferably between 0.1 to 5% by weight, more preferably between 0.1 to 3% by weight.
  • the kinematic viscosity at 40 degrees C of the partial polyol ester is between 40 and 80 mm 2 /s, preferably between 50 and 60 mm 2 /s and the pour point is between -10 and +10 degrees C.
  • the water-soluble rolling oil composition may further comprise other esters in the form of natural oils/fats, for example coconut oil, palm oil, tallow, sunflower oil, and mineral oil, in particular paraffinic mineral oil.
  • esters in the form of natural oils/fats, for example coconut oil, palm oil, tallow, sunflower oil, and mineral oil, in particular paraffinic mineral oil.
  • the water-soluble rolling oil composition may further comprise a range of additives.
  • Preferred additives include antioxidants, for example sterically hindered phenols, aminic antioxidants and butylated hydroxy toluene, antiwear/extreme pressure additives, for example dilauryl phosphate, tri (2-ethylhexyl) phosphate, tricresylphosphate , zinc dialkyl (or diaryl) dithiophosphate, phospho-sulphurised fatty oils, zinc dialkyl dithiocarbamate, mercaptobenzothiazole sulphurized fatty oils and alkyl or aryl polysulphides and emulsifiers, for example nonylphenol ethoxylates, fatty alcohol ethoxylates, polyethylene glycol esters, synthetic alcohol ethoxylates and polymeric surfactants.
  • antioxidants for example sterically hindered phenols, aminic antioxidants and butylated hydroxy toluen
  • a water-soluble rolling oil composition which comprises 15 to 70 % by weight of a partial polyol ester having a hydroxyl value of between 20 and 50 mg KOH/g and a level of polyunsaturation of between 0.01 to 8% by weight in cold steel rolling applications.
  • an oil in water emulsion comprises water and from 1-4% by weight of a water-soluble rolling oil composition for use in cold steel rolling applications which comprises 15 to 70 % by weight of a partial polyol ester having a hydroxyl value of between 20 and 50 mg KOH/g and a level of polyunsaturation of between 0.01 to 8% by weight.
  • a water-soluble rolling oil composition for use in cold steel rolling applications which comprises 15 to 70 % by weight of a partial polyol ester having a hydroxyl value of between 20 and 50 mg KOH/g and a level of polyunsaturation of between 0.01 to 8% by weight.
  • the oil in water emulsion comprises from 2-3% by weight of the water- soluble rolling oil composition.
  • an oil in water emulsion comprises water and from 1-4% by weight of a water-soluble rolling oil composition which comprises 15 to 70 % by weight of a partial polyol ester having a hydroxyl value of between 20 and 50 mg KOH/g and a level of polyunsaturation of between 0.01 to 8% by weight in cold steel rolling applications.
  • Figure One is a pictorial representation of the results obtained in Example One
  • Figure Two is a graphical representation of the results obtained in Example Three.
  • Figure One illustrates two aluminium trays after the heating process for sample A, which is a partial polyol ester according to the invention, and Sample B, which is a comparative ester which is used commercially in water-soluble rolling oil compositions in cold steel rolling.
  • Sample A is a partial polyol ester derived from the reaction of trimethyolpropane with topped coconut oil and hydrogenated C18 monomeric acid in a ratio of 60:40 weight percent.
  • Sample A has a hydroxyl value of 36 mgKOH/g and a polyunsaturation level of 2.4%.
  • Comparative sample B is
  • PRIOLUBE 1427 available ex Uniqema and is an ester of trimethylolpropane with oleic acid having a hydroxyl value of 8mgKOH/g and a polyunsaturation level of 14%.
  • Sample C is a partial polyol ester derived from the reaction of trimethyolpropane with topped coconut oil and hydrogenated C18 monomeric acid in a ratio of 40:60 weight percent. It has a hydroxyl value of 40 mgKOH/g and a polyunsaturation level of 1.6%.
  • the results in the Table demonstrate that the use of partial polyol esters in accordance with the invention have improved clean burning properties with respect to the comparative ester.
  • Example Three The coefficient of friction of Samples A and B was determined at a temperature of 40°C in a Mini-Traction Machine, manufactured and supplied by PCS Instruments in the UK, using a pin-on-disc method.
  • the disc is a smooth steel disc with a roughness parameter of 10nm.
  • the load applied was 5N and the speed of rotation was varied from 0.002 - 4m/s to ensure that the system operated under both boundary and mixed lubrication regimes.
