Abstract
The invention discloses a stainless steel hot-forging lubricant composition. 120BS and II class base oil are compounded to serve as base oil, and the base oil is blended with multiple composite additives to form the composition, wherein the composite additives comprise an antioxidant, an anti-wear agent, an oiliness agent, a metal deactivator, a friction modifier, a corrosion inhibitor and a reinforcing agent. The lubricant composition can be firmly adsorbed to the surface of a forged piece to form oil film protection to avoid adhesion; the lubricant composition has relatively strong dispersibility, adhesion and permeability, the oil film has high strength, good anti-wear property and viscosity-temperature properties, strong extreme pressure property and good thickness stability, and a uniform and continuous oil film is formed between the forged piece and a mold; and the lubricant composition reduces the friction coefficient in the forging process, avoids oil spots, has predominant lubricating performance and stable chemical composition, and does not corrode equipment and metals.
Description
Technical field
The invention belongs to metal working lubricant field, particularly a kind of stainless steel hot forging lubricant composition.
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, distortion complexity 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.Therefore, lubricant used containing solids, namely adds solid lubricant usually in oil base or water base lubricant.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; As 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.
Warm forging, process forging material temperature generally below transformation temperature.Warm forging processing has the advantage of cold forging and forge hot concurrently, and its resistance to deformation is more much smaller than cold forging, and the temperature of blank is lower than forge hot.It, when reducing die pressure significantly, still can obtain gratifying piece surface smooth finish and higher tolerance range, and machined surface quality is well more a lot of than forge hot, is a kind of processing mode having certain magnetism.Its lubricant requires to have the features such as adhesive power is strong, smokeless, product surface smooth finish is good under the high temperature conditions.
Widely used corrosion-resistant material is not only by stainless steel, and there is good thermotolerance (comprising oxidation-resistance and hot strength), it is one of structured material important in aircraft engine, especially those stressed is not very large, work under medium temperature condition (500 ~ 550 DEG C) and require the part compared with high corrosion resistance, many Bian stainless steels manufacture.Stainless steel has the forgeability similar with carbon steel, low alloy steel, and it on different forging equipment, can be shaped with different forging methods.Difference is just under same forging temperature, and stainless steel has higher stress of fluidity than carbon steel and low alloy steel.If be heated to forging temperature in addition, its plasticity can be made significantly to decline.Stainless material has good corrosion resistance nature and weather resistance, makes structural safety reliable, solid durable, is widely used.By different processes, the stainless steel of different shape different structure can be obtained.Heat forged is the forging process of carrying out more than metal recrystallization temperature, it can reduce the plasticity of the resistance to deformation of metal, the as-cast structure changing steel ingot and raising steel, but the operation of thermal forging technology is many, and workpiece accuracy is poor, surface is not bright and clean, and forging easily produces oxidation, decarburization and scaling loss.Because lubricant has certain cooling, cleaning and lubrication, in the course of processing, use the lubricant that over-all properties is good, this problem can be improved preferably, to raising working accuracy, there is good promoter action.
