Abstract
The disclosure relates to a cold rolling fluid, including: (a) a hydrocarbon base including at least 50 wt % of isoparaffins; (b) one or more frictional modifiers selected from among fatty alcohols, fatty acids, fatty amines, fatty acid esters, or polymer esters resulting from the esterification of alpha-olefin copolymers and dicarboxylic acids using alcohols; and (c) one or more phosphorous anti-wear and/or extreme pressure additives. The disclosure also relates to an emulsion containing the rolling fluid and to the use of the rolling fluid for cold-rolling steel.
Claims16
A rolling fluid comprising:
- (a) a hydrocarbon base comprising at least 50% by weight of isoparaffins;
- (b) one or more friction modifiers selected from fatty alcohols, fatty acids, fatty amines, fatty acid esters, or polymer esters obtained by the esterification of alpha olefin and dicarboxylic acid copolymers by alcohols;
- and
- (c) one or more anti-wear and/or extreme pressure phosphorus-containing additives selected from organophosphorus compounds derived from phosphoric acid and/or phosphorous acid, the fluid having a phosphorus content measured according to standard NFT 60-106 at least equal to 500 ppm;
- with the condition that when the fluid contains only phosphoric acid derivatives by way of compound(s) (c) it contains at least one sulphur-containing or phosphorus/sulphur-containing compound and its sulphur content measured according to standard ASTM D 2622 is at least equal to 300 ppm.
An aqueous emulsion comprising a rolling fluid further comprising:
- (a) a hydrocarbon base comprising at least 50% by weight of isoparaffins;
- (b) one or more friction modifiers selected from fatty alcohols, fatty acids, fatty amines, fatty acid esters, or polymer esters obtained by the esterification of alpha olefin and dicarboxylic acid copolymers by alcohols;
- and
- (c) one or more anti-wear and/or extreme pressure phosphorus-containing additives selected from organophosphorus compounds derived from phosphoric acid and/or phosphorous acid, the fluid having a phosphorus content measured according to standard NFT 60-106 at least equal to 500 ppm;
- with the condition that when the fluid contains only phosphoric acid derivatives by way of compound(s) (c) it contains at least one sulphur-containing or phosphorus/sulphur-containing compound and its sulphur content measured according to standard ASTM D 2622 is at least equal to 300 ppm.
