Abstract
The invention discloses a lubricant composition for a cold-spinning stainless steel pipe. The lubricant composition takes MVI 500 base oil as base oil, is matched with multiple additives and comprises an extreme pressure agent, an antiwear agent, an antioxidant, a friction modifier, an oilness agent, a reinforcing agent and an additive. The lubricant composition disclosed by the invention has the advantages of good lubricant property, good cooling property, good wettability, high rust resistance, high adhesiveness, high wear resistance, high wettability, high viscosity-temperature property, high flushing resistance, good chemical stable property, high extreme pressure property, smaller flowing shear stress, good cleanness as well as good properties of corrosion resistance, no toxicity and no odor; the strength of an oil film in a deformation zone is improved, a friction coefficient is reduced, the strength and thickness properties of the oil film are kept stable, the wear of cold-spinning processing equipment is reduced, and the surface smoothness and specification accuracy of the processed stainless steel pipe are improved.
Description
Technical field
The invention belongs to metal working lubricant field, particularly cold spinning stainless steel tube lubricant compositions.
Background technology
Stainless steel chemically composition is said, be a kind of based on iron and charcoal containing the high quality steel compared with multielement.Stainless steel, from physics, chemical property, is a kind of special steel.Stainless steel comprises duriron, non-scaling steel, high temperature steel and resistance alloy etc., and its common feature to resist corrodibility in air and weak corrosive medium, namely not easily gets rusty.Because these steel not easily get rusty, claim them for stainless steel so people flow.
Stainless steel is not absolutely not get rusty, be not corroded, but the amount of getting rusty, the amount of being corroded are few; The process of getting rusty and be corroded is comparatively slow, discover even at all less than.Therefore say, stainless has relative implication, instead of absolute.
The stainless trade mark, composition, different properties, conventional sorting technique is mainly classified by the main chemical compositions (characteristic element) of steel and weave construction and method that the two combines.Chromium system and the large class of chromium nickel system stainless steel two is divided into by the main chemical compositions (characteristic element) in steel.The weave construction of steel refers to the feature of the crystalline structure of steel and the microstructure of steel.Stainless steel is classified by the difference of its weave construction, mainly can be divided into five large classes: i.e. ferritic stainless steel, austenitic stainless steel, Martensite Stainless Steel, duplex stainless steel and PH Stainless Steel.
Cold spinning technology is the more complete processing of Recent study.The development of cold spinning technology mainly develops high value-added product, and its pipe fitting quality of producing is high, and can bear large impact force action, its mechanical property such as plasticity, toughness is better; Under the prerequisite ensureing detail design intensity, alleviate equipment and device own wt; Save metallic substance; Reduce production cost, production efficiency is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tool good lubricating properties, cooling, wetting property, rust-preventing characteristic, increases oil film strength in distorted area, reduces frictional coefficient, keeps oil film strength and thickness stable performance; Adhesivity is strong, and resistance to abrasion, sticky warm nature, wetting property, anti-washability, chemical stability are good; Extreme pressure property is strong, reduces the wearing and tearing of cold spinning processing units, has less flowing shear-stress and detergency, improve surface smoothness and the specification precision of processed stainless steel tube, anticorrosive, nontoxic, tasteless cold spinning stainless steel tube lubricant compositions.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Cold spinning stainless steel tube lubricant compositions, adopt oil based on MVI 500 base oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
