Abstract
1325851 Rolling mills ALCAN RESEARCH & DEVELOPMENT Ltd 10 Jan 1972 [13 Jan 1971] 1767/71 Heading B3M [Also in Division C5] A method of operating an aluminium rolling mill involves charging the lubrication system of the mill with an oil in water emulsion, periodically checking the average particle size of the oil phase, and if necessary increasing or decreasing the particle size to maintain it within an optimum range. The oil phase of the emulsion includes a hydrocarbon oil base, a substantial proportion of a free fatty acid and an amino-soap. The particle size is increased by adding multi valent metallic ions (e.g. aluminium sulphate) to the aqueous phase, and is decreased by adding an alkoli metal soap (or a material which will generate such a soap by reaction free fatty acid), such as sodium hydroxide. By keeping the particle size constant, the surface finish of the rolled products does not deteriate after a few days. The particle size, which can be determined by measuring the metallic ion content, is sufficiently small that the emulsion can be filtered to remove metallic particles with effecting the particles of the oil phase. An example of a suitable lubricant is an aqueous emulsion containing 6% by weight of an oil phase, the phase comprising about 12% oleic acid, and 5% triethanolamine which forms an amine soap emulsifier. An extreme pressure lubricant, such as tricresyl phosphate, and a coupling agent, e.g. diethylene glycol, may also be used.
