Lubricant compositions useful for rolling metals include essentially water added in the range of 5-89.95 mass%; Oxygen-containing compound added in the range of 10-94.95 mass% and represented by the following general formula:n n n n n n n n (Wherein R 1 and R 2 are each independently hydrogen or a hydrocarbon group of 1-18 carbon atoms, R 3 is an alkylene group of 1-6 carbon atoms, p is an integer from 1-30); And an alkali metal salt of a fatty acid of 6-22 carbon atoms, a salt of a fatty acid of 6-22 carbon atoms and an alkanol amine of 1-15 carbon atoms, and a 6-22 carbon atom Salts of fatty acids and nitrogen-containing compounds of the general formula:n n n n n n n n (Wherein R 4 is a hydrocarbon group of 1-24 carbon atoms, R 5 is an ethylene or propylene group, q is an integer of 1-30, X is hydrogen, a hydrocarbon group of 1-24 carbon atoms or a general formula- A salt of a fatty acid selected from the group consisting of a group of (R 6 -O) rH, wherein R 6 is an ethylene or propylene group and r is an integer from 1-30; Wherein the sum of water and the compound of formula (I) is in the range of 80-99.95% by weight, based on the total compositionn n n The ingredients as defined and their content as specified help to improve the rolling performance and to increase the surface gloss of the rolled product. |
