Problems solved by technology

[0003] The cold rolling machine will inevitably produce friction, oxidation and other phenomena during the rolling process. The anti-oxidation and anti-wear properties of traditional water-based lubricants are insufficient, which will cause quality problems such as rough surface of the workpiece and environmental pollution. It may also shorten the service life of the cold rolling machine

Abstract

The invention relates to a cold rolling oil composition. The cold rolling oil composition comprises a first component and a second component, on the basis of the total weight of the first component, the first component is prepared from the following components in percentage by weight: 0.1 to 10 percent of an oxidation and corrosion inhibitor, 0.01 to 1.0 percent of an anti-rust agent, 5 to 50 percent of an extreme pressure anti-wear agent, 0.2 to 1.0 percent of an amine type antioxidant, 0.1 to 0.5 percent of a phenol type antioxidant, 5 to 20 percent of poly-alpha olefin base oil and the balance of mineral type base oil; the second component comprises an anti-foaming agent; the weight ratio of the first component to the second component is 100: (0.001-0.1). The composition has good oxidation stability, extreme pressure wear resistance, corrosion resistance, rust resistance and cooling performance.

Description

technical field [0001] The present application relates to a lubricating oil composition, in particular, to a cold rolling oil-expanding composition. Background technique [0002] Cold rolling technology mainly refers to the technology that uses the plastic deformation characteristics of metal materials to form the required shape and size. The cold rolling and expanding processing line mainly includes the feeding machine, the lathe, the weight sorting machine and the cold rolling and expanding machine. The blank material is loaded on the core roller, the driving roller and the core roller form a cavity, the blank material is continuously rotated under the drive, and after continuous small-scale compression, the blank material will continue to extend and deform to the circumference, so that the inner surface of the blank material is continuously deformed. , The outer diameter continues to expand, and finally achieves the workpiece that meets the requirements. [0003] The co...
