ABSTRACT:
A water-dispersible oil composition for hot rolling aluminum or aluminum alloys having excellent lubricity and emulsion stability and which minimizes heat deterioration over prolonged periods of time contains the following components (a) to (d): (a) a mineral oil, (b) 3 to 30% by weight of a fatty acid or its monoesters, or oils and fats, (c) 0.5 to 10% by weight of a C.sub.4 -C.sub.18 alkyl or alkenyl phosphoric (or phosphorous) acid ester, and (d) 0.1 to 10% by weight of a salt between a polymer and an organic acid salt, wherein the polymer has an average molecular weight of 10,000 to 1,000,000 and is a copolymer of a monomer represented by formula (1): ##STR1## wherein R.sup.1 is H or Me, R.sup.2 and R.sup.3 are independently H or C.sub.1 -C.sub.3 alkyl, m is an integer of 0 or 1, and n is an integer of 1, 2 or 3, and (meth) acrylamide and/or a (meth) acrylic acid salt. Rolled aluminum or aluminum alloy products having excellent surface quality can be obtained using this composition.
