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.327.502 ℃ of fusing points, 1740 ℃ of boiling points, 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, is exactly because it is in air, very easily by airborne dioxygen oxidation, is become the plumbous oxide of grey black, makes its argenteous gloss gradually become intensely dark.The important use of metallic lead is to manufacture store battery.The resistance to deformation of lead alloy is little, can adopt the techniques such as extruding to make sheet material, band, tubing, bar and wire rod.Because shearing, the creep strength of lead alloy are low, under certain load and rolling shear effect, the easily deformable and attenuate of lead alloy becomes paper tinsel shape; And the self-lubricity of lead alloy, running-in ability and damping property are good, and 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.The plumbous bright in color that there is no 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, so it is often used as the container of the material (such as sulfuric acid) that dress corrosion strength is strong.Add a small amount of antimony or other metal can more improve its anticorrosive power.The tensile strength of lead alloy is 3～7kgf/mm
2, more much lower than other metal alloys of great majority.Antimony is for strengthening one of important element of matrix, and only part solid solution, in lead, both can be used for solution strengthening, again can be for ageing strengthening; If but too high levels can make the toughness of lead alloy and solidity to corrosion degenerate.From over-all properties, consider, when lead alloy is used for making the corrosion-resistant elements such as chemical industry equipment, pipeline, to be advisable containing antimony 6% left and right; While being used for making transom, with containing antimony 8%～10% for well.Lead antimony alloy adds a small amount of copper, arsenic, silver, calcium, tellurium etc., can gain in strength, and is called antimonial lead.Lead alloy has and is difficult for the characteristic that penetrated by X and gamma-rays, can make the protective material of radiation work.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of have higher wear-resistant, absorption, carrying, diffusibility, guarantees to form the even oil film of one deck between roll and rolled piece; Reduce the frictional coefficient of rolling, reduce adhesion and coking, and there is better lubricated, 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 is usingd following technical scheme and is solved the problems of the technologies described above: adopt No. 68 total loss systems with oil as base 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 oil for total loss system.
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, use oil as base oil by No. 68 total loss systems, coordinates 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, guarantee to form the even continuous oil film of one deck and certain oil film thickness between roll and rolled piece; Reduce the frictional coefficient in the operation of rolling, reduce adhesion and the coking of rolled piece and roll, and there is better lubricated, cooling, cleaning and the stable performance of thermooxidizing, to reduce the generation of hot rolling embrittlement phenomenon.
