Definitions

  • ABSTRACT In the operation of an aluminum rolling mill, in which the lubricant is an oil-in-water emulsion, having an oil phase consisting of a hydrocarbon oil base, containing a free fatty acid and an amino-soap, the average particle size of the oil phase particles is periodically adjusted by the addition to the water phase either of multivalent metallic ion to increase particle size or of an alkali metal soap or material to generate an alkalimetal soap by reaction with free fatty acid to reduce particle size so as to retain the particle size within an optimum range.
  • the present invention relates to the operation of rolling mills for rolling aluminium (which expression also includes aluminium alloys) and in particular to the lubrication of the aluminium during the rolling process.
  • a rolling lubricant in the form of an oil-in-water emulsion, in which the oil phase comprises a light mineral oil having a substantial porportion of a fatty acid dissolved therein, the emulsion being stabilised by the use of an amine or amide soap.
  • the oil phase comprises a light lcerosinic base oil, in which is dissolved a fatty acid as a load bearing additive and an amine-type soap as a stabiliser for the aqueous emulsion.
  • the amine-type soap is usually a soap formed from an ethan'olamine, which is reacted with some of the fatty acid. It is usual to incorporate other substances, such as tricresyl phosphate, as extreme pressure and anti-wear additive and also surface active agents for spreading the lubricant on the roll surface. It has been found that the particle size at which optimum results are obtained is dependent upon both fatty acid content and the surface active agent content of the oil phase.
  • an amino-soap it is intended to refer to any soap in which the cation includes an -amine,-imine, -amide or -imide group, including ammonium.
  • soap Whilst the addition of soap to the aqueous phase is quite a satisfactory expedient, nevertheless it is preferable to add the free base, which will react with the fatty acid at the surface of the oil phase particles and thus generate the soap at the location of maximum effectiveness. Thus for both reasons of economy and effectiveness the reduction of particle size can most effectively be achieved by the addition of sodium hydroxide or potassium hydroxide.
  • a method of operating an aluminium rolling mill includes charging the lubricant system of the mill with an oil-in-water emulsion, of which the oil phase includes a hydrocarbon oil base, a substantial proportion of free fatty acid and an amino-soap, initially adjusting, if necessary, the particle size of the particles of the oil phase to an average size within an optimum range of sizes by the addition of multi-valent metallic ion to the aqueous phase or by the addition of an alkali metal soap or material which will generate an alkali metal soap by reaction with free fatty acid, depending on whether increase or decrease of the initial average particle size is required, periodically checking the average particle size of the particles of the oil phase and adding sufficient multi-valent metallic ion or alkali metal soap or material which will generate alkali metal soap by reaction with fatty acid to restore the average particle size to a value within the range of optimum sizes.
  • the latter particle-size adjustment is preferably achieved by addition of controlled quantities of an alkali metal hydroxide, preferably sodium hydroxide.
  • an alkali metal hydroxide preferably sodium hydroxide.
  • the same information can be inferentially obtained by determination of the content of the metallic ions of the oil phase.
  • potassium hydroxide it will also be understood that sodium and potassium may be introduced into the aqueous medium in the form of their carbonates and bicarbonates or other strongly alkaline salts.
  • a satisfactory I method of assessing the average particle size of a lubricant emulsion is to estimate the number of particles above a predetermined size in a small volume of the emulsion.
  • N/C optimum number
  • the procedure adopted for determination of the number (N) is to disperse 25 microlitres of emulsion in 250 ml of standard electrolyte and then to count the number of oil droplets above 2p. in size in 0.05 ml of dispersion.
  • C is the concentration by volume of the organic component in the emulsion.
  • the lubricant employed in the lubrication system of a hot-rolling mill was an aqueous emulsion containing about 6 percent of an oil phase, which comprised a kerosinic hydrocarbon base oil, containing about 12 percent oleic acid and percent triethanolamine, which reacts in part with oleic acid to form an amine soap emulsifier for the oil phase.
  • the oil phase may also include an extreme pressure lubricant, such as tricresyl phosphate, and a coupling agent, such as diethylene glycol, to help solubility of the additives.
  • the particle size of the emulsion is primarily dependent on the concentration of oleic acid (or other fatty acid) and triethanolamine (or other soap-forming amino-base) in the oil phase and the amounts of monovalent and multivalent cations.
  • N/C number of number
  • aluminium sulphate was added in small amounts until the predetermined optimum number of about 700 900 was achieved.
  • small samples of lubricant were taken at intervals from the system and the metallic ion content of each of the abovementioned metals in the stable oil-inwater emulsion was measured. An appropriate amount of sodium hydroxide was then added to the lubricant system to restore the balance of monovalent metal ion to multivalent metal ion appropriate to the desired particle size.
  • the present invention provides a method of prolonging the service life of a charge of oil-in-water emulsion lubricant in an aluminium mill over a very long period and thus leads to significant economies in operation.
  • the oleic acid content of the oil phase was increased and also the content of tricresyl phosphate, whilst the ethanolamine content was held in the range of 2 4 percent.
  • the levels of oleic acid and tricresyl phosphate were raised from about 13 percent and 2 percent respectively to about 15 percent and 2.5 percent respectively. Further increase of oleic acid to 17 percent can be achieved without difficulty.
  • corresponding additional amounts of triethanolamine were added. This addition was found to result in an emulsion which gave good rolling results at a significantly lower value of MC (about 200 400) than before.
  • the addition of sodium hydroxide at regular intervals permitted this small particle size also to be maintained over a prolonged period.
  • Additions of multivalent metallic ions for increase of oil droplet size are preferably made while the mill is in operation to avoid as far as possible the fonnation of extra large droplets, which would be removed by filtration.
