The carbon steel warm-forging lubricant composition disclosed by the invention is preferable in flowability and high in diffusion capacity, is capable of forming a layer of uniform and continuous oil film between a forge piece and a mould, has the advantages of good antiwear property and viscosity-temperature property, high extreme pressure property, stability in oil film thickness, good pressure-resistant property, good lubricating property, stability in component, no toxicity and no pungent smell and can be used for protecting a material from being cracked in a forging process, preventing the mould from being damaged and prolonging the service life of the mould.
Description
Technical field
The invention belongs to metal working oil field of lubricant, particularly lubricant compositions is made in a kind of carbon steel warm forging.
Background technology
Carbon steel mainly refers to the iron-carbon that the massfraction of carbon is less than 2.11%, sometimes also referred to as straight carbon steel or carbon steel.The rolling shapes of this uniqueness have considerable advantage than the metal of other types, its usage and function different, the intensity huge due to it and weather resistance, can be used to build nail and parting tool by laying bricks or stones.The carbon content of steel is high, has huge firmness level, and can resist wearing and tearing, and therefore, at metal-cutting machine tool and other machinery of many manufacturings, carbon steel also can be used for manufacturing drill bit, cutter, timber parting tool, saw and metal-cutting machine tool.
Ferrous materials has resource relative abundance, industrial scale is huge, processing and manufacturing is easy, performance is various reliably, with low cost stablizes, uses and recycles the features such as convenient, is widely used material in infrastructure construction, industrial equipments manufacture and people's daily life.Make great efforts accumulation untiringly through the mankind and create, ferrous materials Science and Technology achieves huge progress.Improve the developing direction that cleanliness factor, uniform formation and crystal grain thinning are following carbon steel material technique.Use warm swaging technique in order to process carbon steel, its high-precision requirement can be realized, and steel utilization ratio can be improved and increase the service life.In recent years, cold swaging technique is developed rapidly at industrial circle and is played a significant role, and has become the important channel of improving product competitiveness.
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.Then flat-die forging, die forging, cold-heading, radial forging, extruding, roll forming, roll forging, rolling etc. can be divided into by manufacturing process.The distortion that blank produces under stress not by the title flat-die forging of outside restriction, also claims open type forging substantially.The blank deformation of Forgingother method is all subject to the restriction of mould, is called that close pattern forges.The forming tool of roll forming, roll forging, rolling etc. with have relative rotary motion between blank, pointwise, asymptotic pressurization and shaping are carried out to blank, therefore are also called rotary swaging.Can eliminate the defects such as cast condition that metal produces in smelting process is loose by forging, optimize heterogeneous microstructure, simultaneously owing to saving complete metal streamline, the mechanical property of forging is generally better than the foundry goods of same material.
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.The recrystallization temperature of usual steel is greatly about about 750 DEG C, and when forging more than 700 DEG C, because energy of deformation can obtain dynamic release, Forming Resistance sharply diminishes; When 700 ~ 850 DEG C of forgings, forging oxide skin is less, and surface decarburization phenomenon is comparatively slight, and forging ' s block dimension change is less; When forging more than 950 DEG C, although plastic force is less, seriously, forging ' s block dimension changes greatly for forging oxide skin and surperficial Off carbon phenomenon.Thus in the scope of 700 ~ 850 DEG C, forging can obtain quality and all reasonable forging of precision.Many factors is depended in the selection of forging lubricant, wherein important consideration forging temperature, Forging Equipment Speed, the complexity of distortion and mold surface finish etc.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and has that mobility is better, diffusibility is strong, the oil film of one deck uniformly continous can be formed between forging and mould, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, oil film thickness is stablized, good pressure-resistant performance, protection material does not ftracture at forging process and avoids burn failure, extends die life; Lubricity is good; Component is stablized, and lubricant compositions is made in carbon steel warm forging that is nontoxic, that have no irritating odor.
