Abstract

The invention discloses a band steel cold rolling oil composition and a preparation method thereof. The band steel cold rolling oil composition comprises the following components in percentage by mass: 70-90% of basic oil, 0.1-2% of an antioxidant, 0.5-4% of a slow release agent, 2-10% of an extreme pressure lubricant and 1-20% of an emulsifier. The preparation method comprises the following steps: putting basic oil into a reaction tank according to a ratio, and stirring and heating to an appointed temperature range; putting the antioxidant and the slow release agent into the mixture obtainedin the step 1, keeping the temperature range, and stirring till solids are completely dissolved; cooling the obtained mixed; putting the extreme pressure lubricant and the emulsifier into the mixtureaccording to a ratio, keeping a temperature range after cooling, and stirring till the mixture is completely uniform and transparent, thereby obtaining a finished product of the composition. Comparedwith the prior art, the band steel cold rolling oil composition is balanced in overall lubrication property and stability, cold rolling oil has good lubrication properties, and the maintenance and management difficulties can be reduced.

Description

technical field [0001] The invention belongs to the technical field of rolling oil, and in particular relates to a strip steel cold rolling rolling oil composition and a preparation method thereof. Background technique [0002] Rolling liquid is an essential oil product in the cold rolling process of strip steel, which plays the roles of lubrication, cooling, cleaning and rust prevention. When used on site, the rolling liquid is usually mixed with a certain proportion of water (usually the water content is 95-98%), and then it is used as an emulsion after stirring. The lubricity and stability of the emulsion are very important for the use of rolling liquid. Performance matters. [0003] Good lubricity, low rolling force, good shape and high surface quality after rolling. Stable emulsions have good cleanliness and less oil slick, which is convenient for maintenance and management, but their lubricity and cleanliness will be affected; unstable emulsions have good lubricity, ...
