Problems solved by technology

[0009] CN201510362873.1, a cold-rolled emulsion odor gas purification device and method, this technology uses technology to filter or centrifugally collect odor-rich rolling oil and other substances in the emulsion to obtain gas with lower odor, Then the catalyst rich in iron and manganese is used to further decompose the odorous chemical substances in the gas. The advantage of this technology is that it is versatile and can widely treat various emulsions with good treatment effect. However, due to the use of a very professional catalyst, The overall technical economy is low, and it is not suitable for large-scale promotion and use
[0010] CN201610173105.7, a water-based metalworking lubricating fluid containing nano-molybdenum disulfide and its preparation method, mainly uses various water-soluble lubricating compounds, such as triethanolamine, aqueous sodium polyacrylate, silane coupling agent and sodium diacetate and other substances, and then use nano-molybdenum disulfide powder as a cold-rolling lubricant. Since this technology completely uses water-soluble substances, it can avoid the odor problem of traditional

Abstract

The invention discloses cold rolling oil with high lubricity and less odor. The cold rolling oil mainly comprises, by mass, 40-90% of high-viscosity lubricating synthetic ester, 0.5-2.5% of surfactants, 0.2-2% of anti-rust agents, 2.0-6.5% of anti-wear agents at extreme pressure, 0.5-1.5% of anti-oxidation additives and the balance of deep refined mineral oil. The high-viscosity lubricating synthetic ester is synthetic ester having the kinematic viscosity of 80 mm<2>/s<-1> or above at 40 DEG C. The cold rolling oil has the advantages that the odor of emulsions for cold rolling units can be effectively controlled from the source for a long term, and reduction of the lubricity of the production process can be avoided.

Description

technical field [0001] The invention relates to a rolling oil used in the production process of steel cold rolling, and more particularly relates to a rolling oil for steel cold rolling with high lubricity and low odor and a use method thereof. Background technique [0002] In the modern steel cold rolling production process, usually to lubricate, reduce wear, clean and prevent rust, the emulsion is sprayed to the roll gap and the surface of the strip, and the rolling oil in the emulsion enters the rolling deformation zone Finally, it first attaches to the surface of the roll and the strip to form a thin lubricating oil film to lubricate and prevent rust, and the water can take away the heat of deformation and friction during the rolling process to play a cooling role. The usual cold rolling emulsion is a chemical product obtained by mixing 1-3% rolling oil and 97-99% water according to mass percentage. [0003] Due to the huge heat generated by the strip steel in the cold ...
