Abstract
The invention discloses a lubricating agent composition for warm forging of stainless steel. According to the lubricating agent composition, 90BS base oil is taken as base oil and matched with various composite additives including an antioxidant, an anti-wear agent, an oiliness agent, a metal deactivator, a friction improving agent, a corrosion inhibitor and a reinforcing agent. The lubricating agent composition disclosed by the invention is relatively high in diffusivity, adhesivity and permeability, large in oil film strength, good in wear resistance and viscosity-temperature property, high in extreme pressure property and good in oil film thickness stability, can be used for forming a uniform and continuous oil film between a forge piece and a mold and reducing the friction coefficient during forging, and is remarkable in lubrication performance, stable in chemical constitution and free of corrosion to equipment and metals.
Description
Technical field
The invention belongs to metal working oil field of lubricant, particularly lubricant compositions is made in a kind of stainless steel warm forging.
Background technology
By the method for hammering or compacting, apply power to metal stock and make it to produce viscous deformation, make the product that shape, size and performance all meet the requirements, this plastic processing method is called as forging.They are different by the instrument used, and can be divided into open die forging (flat-die forging) and the large class of closed die forging (die forging) two.Forging feature be: the forging quality of production is high, can bear large shock action, its mechanical property such as plasticity, toughness and working accuracy better; Save metallic substance; Production efficiency is high.
Stainless development have passed through the course of last 100 years, and because it has unique corrosion resisting property, good processing characteristics and the appearance of fineness, be applied to various fields, such as chemical industry, oil, space flight, the energy, weaving, light industry etc.Because it is of many uses, absolutely can be recovered application, and along with the continuous progress of Technology and the reduction of production cost, stainless steel more and more gos deep into the life of people.Use warm forging technology to process stainless material, can improve steel strength, improve stainless material utilization ratio, reduce the energy and expenditure of time, the forging through warm forging processing has good surface quality.In forging process, blank is in warm forging forming process, and deformation extent is comparatively large, and metal fluidity requires that will there be good purification and swabbing in blank face.And the lubricant used in warm forging fabrication technique should have stronger diffustivity, adhesivity, perviousness, oil film strength is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, oil film thickness stability, resistance to pressure, even distribution and oilness are good, make it between blank surface and mould, form lubricating oil film, reduce the wearing and tearing of mold cavity surface simultaneously, be beneficial to the demoulding after forging workpiece.
For steel forge piece, be usually called warm forging by below recrystallization temperature and higher than the forging of normal temperature.The object of Bian warm forging technique obtains net-size forging, and the advantage of warm forging is also just precision and the quality that can improve forging, do not have again the plastic force that cold forging is large like that simultaneously.The application of warm forging technique and forging material, forging size, forging complexity have close relationship.Stainless steel forgings refers to that stainless material is applied in pressure, is moulded the object of the suitable force of compression of the shape Ge of requirement by viscous deformation.This strength typical case is by using iron hammer or pressure to realize.By texturing temperature, forging can be divided into again forge hot (forging temperature is higher than the recrystallization temperature of blank metal), warm forging (forging temperature is lower than the recrystallization temperature of metal) and cold forging (normal temperature).About interior 460 DEG C of the recrystallization temperature of steel, but generally adopt 800 DEG C as dividing line, be forge hot higher than 800 DEG C; Warm forging or half forge hot is called between 300 ~ 800 DEG C.Stainless steel warm forging mainly solves large and sticking to mould ability this two problems by force of stainless steel resistance to deformation.Therefore the using method with it is selected in the selection of warm forging temperature, particularly lubricant, is the key of carrying out stainless steel warm forging smoothly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has stronger diffustivity, adhesivity, perviousness, and oil film strength is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, oil film thickness stability, ensure the oil film forming uniformly continous between forging and mould; Reduce the frictional coefficient in forging process, lubricity is given prominence to; Chemical constitution is stablized, and lubricant compositions is not made in the stainless steel warm forging of etching apparatus and metal.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Lubricant compositions is made in a kind of stainless steel warm forging, adopts oil based on 90BS base oil, coordinates multiple composite additive, and the one-tenth of its mass percent is separately grouped into:
| Component | Mass percent content |
