Abstract (en)

[origin: FR2820431A1] The invention concerns a method for cold rolling metals using an aqueous lubricant comprising: (1) at least a mixture based on at least an acid selected among saturated or unsaturated mono- or poly-carboxylic acids, comprising 5 to 40 carbon atoms; at least an acid phosphate ester of formula (RO)x-P(=O)(OH)x', wherein: R is a hydrocarbon radical, optionally polyalkoxylated; x and x' being equal to 3; the carboxylic acid and/or the acid phosphate ester being optionally neutralised by an organic or mineral base; and (2) at least a natural or synthetic wax exhibiting a melting point not less than 50 DEG C and having an average particle size ranging between 0.5 and 10 mu m. The use of said lubricant enables to increase the productivity of the method by at least 15 % relative to a method using a conventional lubricant.
