Abstract

The invention discloses a cold rolled silicon steel rolled oil composition. The composition comprises the following components in percentage by weight: 60 to 90 percent of alcohol ester oiliness agent, 5.0 to 12 percent of animal and vegetable oiliness agent, 2.0 to 12.0 percent of nonionic surfactant, 0.6 to 8 percent of phosphate antiwear additive and 0.5 to 8 percent of antirust additive. The rolling lubricating property of the cold rolled silicon steel rolled oil composition is high; the cleanness of the rolling environment and a memorial archway is good; and the degreasing property, the rust-proof performance and the anti-oil burn property are high.

Description

technical field [0001] The invention belongs to a lubricating composition for metal processing technology, in particular to a cold rolling silicon steel rolling oil composition. Background technique [0002] Silicon steel sheet, also known as silicon steel sheet, is a ferrosilicon soft magnetic alloy with extremely low carbon content. Generally, the silicon content is 0.5-4.5%. It is mainly used to make iron cores for various transformers, motors and generators. The manufacturing technology and product quality of silicon steel sheets have become one of the important symbols to measure a country's special steel production and technological development level. In recent years, with the rapid development of the world economy, the demand for cold-rolled silicon steel sheets is increasing, and the requirements for its surface quality are getting higher and higher. Cleanliness, excellent degreasing properties, rust resistance, oil burning resistance, cycle stability, and handleabi...
