Abstract
A hot rolling lubricant for plate strips of lead and lead alloy is prepared by employing No.68 total-loss system oil as base oil and mixing with multiple composite additives. The composite additives comprise a wear-resistant agent, an oiliness agent, an anti-oxidant, an antifoaming agent, an emulsion-resistant agent, a metal deactivator and a friction improver. The hot rolling lubricant has relatively high wear-resistant capability, absorption capability, bearing capability and diffusion capability, and guarantees to form a layer of uniform continuous oil film with a certain oil film thickness between a roller and a rolled piece; the hot rolling lubricant helps to reduce the friction coefficient during rolling, reduce adhesion and coking of the rolled piece and the roller; and the hot rolling lubricant has relatively good lubricity, cooling performance, cleaning performance and thermal oxidation stability, and helps to reduce generation of hot rolling embrittlement phenomena.
Description
Technical field
The invention belongs to lead and alloy plate strip hot-rolled lubricant field thereof.
Background technology
Lead is bluish silvery white heavy metal, and it is toxic, is a kind of malleable main group metal.Fusing point 327.502 DEG C, boiling point 1740 DEG C, density 11.3437g/cm
3, hardness 1.5, quality is soft, and tensile strength is little.Lead is easy to get rusty---oxidation.Lead is often grizzly, be exactly due to it in atmosphere, very easily become the plumbous oxide of grey black by the dioxygen oxidation in air, make its argenteous gloss gradually become intensely dark.The important use of metallic lead manufactures store battery.The resistance to deformation of lead alloy is little, and the techniques such as extruding can be adopted to make sheet material, band, tubing, bar and wire rod.Because the shearing of lead alloy, creep strength are low, under certain load and rolling shear effect, lead alloy is easily deformable and thinningly become foil-like; And the self-lubricity of lead alloy, running-in ability and damping property are good, noise is little, because of but good bearing metal.Graphite metal and tinhase bearing metals are referred to as Babbitt metal, can make the Locomotive Bearing of high-load.Do not have the plumbous bright in color of zone of oxidation, density is high, and hardness is very low, and extensibility is very strong.Its conductivity is quite low, and corrosion resistance is very high, and therefore it is often used as the container of the strong material (such as sulfuric acid) of dress corrosion strength.Add the corrosion resistance that a small amount of antimony or other metal can improve it more.The tensile strength of lead alloy is 3 ~ 7kgf/mm
2, more much lower than other metal alloys of great majority.Antimony is for one of important element strengthening matrix, and only part is solid-solution in lead, both can be used for solution strengthening, and can be used for ageing strengthening again; If but too high levels, the toughness of lead alloy and solidity to corrosion can be made to degenerate.Consider from over-all properties, when lead alloy is for making the corrosion-resistant element such as chemical industry equipment, pipeline, to be advisable containing antimony about 6%; During for making transom, to contain antimony 8% ~ 10% as well.Lead antimony alloy adds a small amount of copper, arsenic, silver, calcium, tellurium etc., can gain in strength, be called antimonial lead.Lead alloy has not easily by the characteristic that X and gamma-rays penetrate, and can make the protective material of radiation work.
Summary of the invention
The technical problem to be solved in the present invention be to provide one have higher wear-resistant, absorption, carrying, diffusibility, ensure between roll and rolled piece, form the even oil film of one deck; Reduce the frictional coefficient of rolling, reduce adhesion and coking, and there is better lubrication, cooling, cleaning and thermal oxidation stability energy, to reduce lead and the alloy plate strip hot-rolled lubricant thereof of hot rolling embrittlement generation.
The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 68 total loss system oil, coordinate multiple composite additive, its each component and mass percent thereof are:
| Component | Content (mass percent) |
| Base oil | Surplus |
| Anti-wear agent | 4.0%～5.0% |
| Oiliness improver | 6.0%～8.0% |
| Kilfoam | 0.001%～0.003% |
| Oxidation inhibitor | 0.3%～0.5% |
| Non-emulsifying agent | 0.3%～0.5% |
| Metal passivator | 0.3%～0.5% |
| Friction improver | 3.0%～4.0% |
Base oil is No. 68 total loss system oil.
Anti-wear agent is that dibutyl dithiocaarbamate is plumbous.
Oiliness improver is plam oil.
Kilfoam is dimethyl silicone oil.
Oxidation inhibitor is N-phenyl-a-naphthylamines.
Non-emulsifying agent is amine and epoxy compounds condenses.
Metal passivator is dialkyl diphenylamine.
Friction improver is whiteruss.
Lead of the present invention and alloy plate strip hot-rolled lubricant thereof, with oil based on No. 68 total loss system oil, coordinate multiple composite additive.Comprise anti-wear agent, oiliness improver, oxidation inhibitor, kilfoam, non-emulsifying agent, metal passivator, friction improver.There are higher wear-resistant, absorption, carrying, diffusibility, ensure between roll and rolled piece, form one deck uniformly continous oil film and certain oil film thickness; Reduce the frictional coefficient in the operation of rolling, reduce adhesion and the coking of rolled piece and roll, and there is the stable performance of better lubrication, cooling, cleaning and thermooxidizing, to reduce the generation of hot rolling embrittlement phenomenon.
