Disclosed is a quenching medium for treating a heated metal part, said medium comprising water and a polyacrylate terpolymer comprising acrylamide and/or methacrylamide monomer units, acrylic acid and/or methacrylic acid monomer units and alkyl alkoxylate allyl ether monomer units where the acid groups are in the form of an alkali metal salt and where the alkyl alkoxylate allyl ether monomers are of the formula where n is an integer from 1 to about 30, R is ethylene, propylene or butylene and G is an alkyl group of 8 to 30 carbon atoms. Also disclosed is a method for quenching a heated metal part, which process comprises immersing said metal part in the quenching medium. Also disclosed are the polyacrylate ternary copolymers.

Metal quenching medium

The present invention relates to a cold rolling process for rolling hard metal or metal alloys, comprising applying an effective amount of an oil composition comprising a base stock oil and, based on the total weight of the composition, from 1 to 80% by weight of di(2-ethylhexyl)adipate. Example of hard base metals include steel and nickel.

Cold rolling process for rolling hard metal or metal alloys

The present invention relates to a water-soluble aluminium and aluminium alloys hot rolling composition comprising a base stock oil and, based on the total weight of the composition, from 1 to 80% by weight of a combination of: a monoester of a fatty acid with a polyol and a tetraester of a fatty acid with pentaerythritol; the weight monoester:tetraester ratio of said combination ranging from 1:20 to 10:1. The invention also relates to an oil-in-water emulsion, to a hot rolling process and to the use of the oil-in-water emulsion in a hot rolling process.
