Finishing mill bearing oil research and development

The technical index of the oil film bearing oil according to the working condition of the use of the finishing mill oil film bearing oil, the oil film bearing in finishing mill oil should have good viscosity-temperature properties, excellent resistance to emulsification properties, enough anti-wear and extreme pressure performance, good rust resistance, oxidation stability and anti-foam properties are comprehensive performance. About the quality of the oil film bearing oil technical indicators, has not yet been unified formal standards in the world. In steel for professional only puts forward the principles of ASLE requirements, mainly in the United States MORGAN company rules as a benchmark. Our country has not yet establish oil film bearing oil gb. So we developed the Construction Of KOYO Bearing h t t p:/ /w w w.fagbearings-hk.c o m/KOYO-Bearings.h t m l oil is still using the steel (USS) 136 MobilVacuoline500 mobil oil company quality standard and reference series quality indicators.
　　Base oil refining depth and the types directly affect the oil emulsification resistance, viscosity and oxidation stability and performance, etc. Hydrogenated base oil with high viscosity index, good low temperature fluidity, shallow color, demulsification performance is good, against the susceptibility of good wait for a characteristic, is a good lubricant base oil. This research adopts the hydrogenated oil of the oil film bearing in high speed wire rod finishing mill as the main base oil of 1 component. The oil of the oil film bearing in high speed wire rod finishing mill should have good viscosity-temperature properties, excellent resistance to emulsification properties, enough anti-wear and extreme pressure performance, good rust and corrosion performance, oxidation stability and performance and comprehensive performance such as foam resistance. According to the working state of the oil film bearing in high speed wire-rod mill oil and performance requirements, the demulsification performance is the key to product performance. The selection of the additives must ensure oil demulsification performance. So should choose appropriate active additives main agent of the extreme pressure antiwear agent containing sulfur, phosphorus, and should have oxygen and corrosion resistance, etc. To ensure the comprehensive performance of oil products at the same time, should also be added in the formulation of adequate anti-rust agent, preservative, antioxidant agent, antifoaming agent and demulsifier, etc.
　　Antiwear agent, can reduce the friction coefficient of base oil and increase the oil film strength. Choose moderate activity against the emulsifying performance is affected SanJiaFen phosphate ester (T306) as antiwear agent. Sulfur extreme pressure agent: to meet the requirements of mill lubrication of gear transmission system, should add smaller effects on oil demulsification performance sulfur extreme pressure additives. Optional second dibenzyl sulfide (T322) as extreme pressure agent. Emulsifier: resistance to improve the emulsification resistance, amine and epoxy ethane condensation compound (T1001) as an emulsifier. Other functional agent: according to many years of experience in research of lube oil, antioxidant 2, 6 - BHT (T501), namely, metal anticorrosion agent of live agent selected thiamethoxam two thiazole derivatives (T561), anti-foam agent selected methyl silicone oil. In order to make the oil film bearing oil demulsification performance is good, without introducing macromolecular compounds in the system, as far as possible namely, viscosity index improver.
Compound formula research and results according to the above the choice of the additive, preliminary selected extreme pressure agent sulfur agent, anti-wear agent containing phosphorus agent B, composite emulsifier and antioxidant preservatives C D oil of the oil film bearing in high speed wire rod finishing mill as the function of ideal additive. In compound formula introduced in emulsification and have little influence on other anti-rust agent, anti-foam agent selected F E, solve the oil film bearing oil anti-wear properties, emulsifying properties and corrosion resistance requirements. Lubricating oil of each component in the compatibility is important, the effect of proper compatibility can be enhanced, which is better than the sum of the effects of several additives used alone, compatibility may not when cancel each other out the effect of additive, and even have the opposite effect. According to the research of the lubricating oil compound recipe of traditional experience, usually by orthogonal experimental method to determine the optimal addition amount of compound recipe of various additives. For this design L9 (34) orthogonal experiment to investigate the best addition amount of additives.
