Abstract

The invention discloses low-odor rolling oil for steel cold rolling. The rolling oil comprises the following components in percentage by mass: 0-30% of natural oil, 50-90% of synthetic lubricating grease, 0.8-4.5% of a surfactant, 2.0-6.5% of an extreme-pressure antiwear agent and 0.5-1.5% of an antioxidation additive. An emulsion prepared by using the rolling oil can effectively reduce the smellcaused by the natural oil with stink in the rolling oil, and the odor of the rolling oil is controlled to be at a very low level through reducing use of active sulfur compounds.

Description

technical field [0001] The invention relates to rolling oil, in particular to a low-odor rolling oil for cold rolling of steel and its application method. Background technique [0002] In the production of modern cold rolling mills, usually in the production of cold rolling technology, a complex emulsion system is used to spray a certain amount of emulsion on the roll gap and the surface of the strip. After the emulsion enters the rolling deformation zone, it first adheres to the The surface of the roll and the strip forms a thin lubricating oil film for lubrication, and the water can take away the heat of deformation and friction during the rolling process to play a role in cooling. The so-called cold rolling emulsion is a chemical product obtained by mixing 1-3% rolling oil and 97-99% water according to mass percentage. [0003] The cold rolling emulsion is sprayed in large quantities during production (usually >20m 3 / h), under the action of a large amount of heat fr...
