Abstract

The invention discloses a lubricating oil composition and use thereof, wherein the lubricating oil composition comprises 40-80 wt% of mineral oil, 10-50 wt% of oily agent, 4-10 wt% of emulsifying agent, 1-5 wt% of inhibitor, 2-5 wt% of antiwearing agent, 0.1-1.0 wt% of solubility promoter, 0.1-2.0 wt% of anti-oxidizing agent, and 0-0.5 wt% of metallic deactivator.

Description

technical field [0001] The invention belongs to the field of lubricant and its application, in particular to a lubricating oil composition for rolling copper and its alloy and its application. Background technique [0002] The rolling of copper and its alloys is usually carried out under two lubrication methods, one is full oil rolling, and full oil rolling generally uses light mineral oil to add a certain amount of additives such as oily agents, preservatives, and antioxidants. Lubricating and cooling medium, commonly used in the finish rolling of copper and its alloys; the other is emulsion rolling, in the process of semi-finished product rolling due to the large amount of deformation to generate large deformation heat, it is necessary to use emulsion as lubrication and The cooling medium takes away a large amount of heat, which is beneficial to the shape control. Since copper is a very active metal, it is easy to change color when exposed to water. Therefore, in addition...
