Abstract

The invention discloses rolling oil for aluminum magnesium alloys. The rolling oil comprises, by weight, 50-86% of alcohol ester oiliness additive, 0.5-5% of nonionic polymer surfactant, 2-15% of a nonionic ester ether surfactant, 0.53-15% of a pole tension anti-wear additive, 0.1-2% of a metal deactivator, 0.01-5% of an antifogging agent and 10-12% of an antioxidant. According to the rolling oil, the lubricating property is good, oil film can not be broken in 15-30% of pass rolling, the bonding between rolls can be effectively prevented, the rolling pressure can be reduced, and the abrasion can be reduced; and the rolling heat can be brought due to proper cooling performance, rolls and rolled pieces can be protected, and the rolling oil has good antioxidant and anti-corrosion performances and good annealing detergence without annealing oil spots.

Description

technical field [0001] The invention relates to a lubricating oil for metal processing, in particular to an aluminum-magnesium alloy rolling oil. Background technique [0002] With the rapid development of the automobile and home appliance industries, the demand for cold-rolled alloy sheets is increasing, and the requirements for the surface quality of cold-rolled alloy sheets are getting higher and higher, especially for the lubricating performance of rolling oil and the cleaning performance of rolling mills. , Annealing detergency commission more stringent requirements. [0003] At present, the commercially available rolling oil products generally have problems such as insufficient extreme pressure lubrication performance, heavy oil mist, poor surface cleanliness after rolling and poor annealing cleanliness, which increases the wear between the roll and the rolled piece, reduces the surface quality of the workpiece and The deterioration of the processing environment great...
