Abstract

The invention discloses a cold-rolled sheet drawing oil composition to solve the defect of poor lubricating property nowadays, which is characterized by the following: this compositing includes 60-90 mass percent polyatomic alcohol ester oiliness agent, 0.5-5.0 mass percent non-ionic high molecular surfactant, 2.0-15.0 mass percent non-ionic ester ether type surfactant, 0.53-15 mass percent sulfide extreme pressure antiwear agent and 0.51-5 mass percent metal deactivator. This drawing oil possesses good lubricating property, milling train clean property and good annealing peace and quiet property.

Description

technical field [0001] The invention belongs to a lubricating composition for metal processing technology, in particular to a cold rolling sheet rolling oil composition. Background technique [0002] With the rapid development of the automobile and home appliance industries, the demand for cold-rolled sheets is increasing, and the requirements for the surface quality of cold-rolled sheets are getting higher and higher. The rapid development of cold-rolling equipment and related technologies has made cold-rolled sheets High-speed production and large-scale production. The relevant head rolling is transformed into a CDCM (Pickling Combined Mill) unit, which leads to the lubricity of the rolling oil, the cleanliness of the rolling mill, the annealing cleanliness, the cycle stability, and the processability of the waste rolling oil. Sex, etc. put forward stricter requirements. [0003] The cold rolling oils currently used in the market can be divided into two categories: [0...
