Abstract
The invention discloses a low-alloy steel hot-forging lubricant composition. #680 cylinder oil used as base oil is matched with multiple composite additives, including an antioxidant, an anti-wear agent, an oily agent, a metal deactivator, a friction modifier, a corrosion inhibitor and a reinforcing agent. The lubricant composition disclosed by the invention is relatively low in viscosity, large in heat capacity, high in cooling and washing property, good in lubrication property and extreme pressure property, stable in component and property, free of corrosion to metal and equipment and free of toxicity or pungent smell, and the phenomenon that a forge piece is adhered to a mold is reduced.
Description
Technical field
The invention belongs to field of lubricant, particularly a kind of low alloy steel heat forged lubricant compositions.
Background technology
Forging, divides the multiple working methods such as flat-die forging, at a high speed forging, roll forging and precision die forging by processing mode; Cold forging, warm forging and forge hot etc. can be divided into again with the moulding process temperature condition of material.The object of forging mainly improves the degree of irregularity of base material interalloy compound distribution, thus improves the mechanical property of forging.Forging processing is defined as: compression or jumping-up and in closed mould, make crude green body shaping and unnecessary metal is entered the process of burr groove in open die.It should be noted that, forging process can carry out under impact (hammering) condition, and also can carry out under (pressing machine forging) condition at a slow speed, processing temperature can be room temperature or high temperature
The effect of forging lubricant: forging can at room temperature be carried out, and also can carry out under middle temperature or high temperature, mould can use open die, die forging mould or closed mould.It is a kind of intermittent type course of processing.The effect applying lubricant has: reduce forging load, promotes that metal flows in a mold, prevents mould stuck, reduce die wear, as the thermal boundary between workpiece and mould, is convenient to the de-forging of workpiece.
The characteristic that forging lubricant should possess: moistening metallic surface equably, in case local is unlubricated; There is no residue, there is certain cooling effect; Can not mould be corroded, but protection Tu layer should be provided to mould, wetting property, good adhesion; Be suitable for autofeed or spray Tu feed; Free from environmental pollution, waste liquid easily processes, and does not form harmful material; Excellent storage stability, is mixed into hydraulic efficiency oil and is easily separated; Concentrated shape lubricant can be diluted to the forging process being satisfied with different lubricating requirement; Price economy is reasonable.In addition, the lubricant that forging process is used has also having of liquid state solid-state.
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.
In the forge hot course of processing, service temperature and die temperature are all very high, and conventional liquid lubricant is easy to volatilization.The hot forging temperature of such as aluminium alloy also has 400 DEG C; And the hot forging temperature of high-melting-point low-alloy steel grade can reach more than 1650 DEG C.Therefore, lubricant used containing solids, namely adds solid lubricant usually in oil base or water base lubricant.As graphite, molybdenumdisulphide and other solid lubricants.Reduce temperature and can increase the mold use life-span, particularly keeping mould, that large temperature variation does not occur is very important, because significantly the changing caused cool-hot fatigue and can cause burn failure of die temperature.Such as: when forging nickel-base alloy, high-meltiing alloy and titanium workpiece, also often can adopt glass coating, lubricate on the one hand, stops workpiece oxidation on the other hand.
Cold forging, room temperature forges lubricant used based on oil lubricant.If flow of metal rate is less, as when cold-heading or press forging, available high viscosity fluid; If impact velocity is very high, as high-voltage high-speed forging, then the low viscous lubricant of Bian.Cold Forging has very high contact pressure, usually adopts the lubricating system of chemical reaction film.Cold forging lubricant Main Function used reduces frictional wear, prevents metallic surface from occurring concave point or sintering.Under comparatively harsh cold forging condition, the lubricant of tool extreme pressure property must be adopted, or adopt compound to cover the lubricating process of film forming.
Such as: metal plastic deformation degree is comparatively large, or when processing some hard metals or steel alloy, must adopt the lubricant with extreme pressure property, or Bian phosphoric acid salt cover the lubricating process of film forming.Typical usage be phosphate coating for carbon steel or low alloy steel, oxalate be used for stainless steel.
Summary of the invention
It is lower that the technical problem to be solved in the present invention is to provide a kind of viscosity, and thermal capacitance is large, and cooling, Cheongju washes ability by force, can reduce the adherent phenomenon of forging and mould; There is good lubricity and extreme pressure property simultaneously; Composition and stable performance; To metal and equipment corrosion-free; Nontoxicity, the low alloy steel heat forged lubricant compositions had no irritating odor.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of low alloy steel heat forged lubricant compositions, adopt oil based on No. 680 locomotive oils, coordinate multiple composite additive, the mass percent of its each component is:
