The invention relates to a lubricating agent for the cold rolling of vanadium and vanadium-alloy sheets. The lubricating agent is characterized in that total-loss system oil No.15 is used as base oil and is coordinated with multiple compound additives which comprise an anti-wear agent, an oiliness agent, an antioxidant preservative, an antioxidant, an anti-foaming agent and a demulsifying agent. The lubricating agent has the property of reducing the hot adhesion of rollers and rolled pieces, low viscosity and low sulfur content as well as good cooling, lubricating, cleaning, diffusion and thermal oxidation stability mineral oil and does not generate oil patches during annealing.
Description
Technical field
The invention belongs to a kind of vanadium and alloy plate strip cold-rolling lubricant field thereof.
Background technology
Vanadium is a kind of silver-gray metal.1919 ± 2 ℃ of fusing points, belong to the row of high-melting-point rare metal.Its boiling point 3000--3400 ℃, the density of vanadium is every cubic centimetre of 6.11 gram.Pure vanadium has malleability, and apparently, vanadium and iron are worn silver-gray clothes equally, but vanadium is much harder than iron, and at normal temperatures, vanadium very " is cooled down ", and it can be not oxidized, even it is heated to 300 degree Celsius, it still as before, remains brightly lit.It is the corrosion of not water funk, various diluted acid and alkali lye also.In various metals, it can be very special.
Vanadium mainly is used in metallurgy, the same with other iron alloy, as catalyzer and reductive agent, but, because vanadium can increase wear resistance and the ductility of steel, makes it at excellent steel, special steel, in bar, sheet material and section bar, enjoys favor.Only need in steel, add the vanadium of percentum, just can make the elasticity of steel, intensity increase, resistance to wear fabulous with anti-cracking property, not only high temperature resistant but also anti-strange cold, in departments such as automobile, aviation, railway, electronic technology, national defense industry, be found everywhere the trace of vanadium.In addition, the oxide compound of vanadium has become one of optimum catalyst in chemical industry, and the title of " chemical bread " is arranged.Vanadium has physicals and the chemical property of numerous excellences, thereby the purposes of vanadium is very extensive, the metal that is otherwise known as " VITAMIN ".Initial vanadium is applied to iron and steel mostly, by tissue and the crystal grain of refinement steel, improves the grain coarsening temperature, thereby plays intensity, toughness and the wear resistance that increases steel.Afterwards, found again gradually the excellent improving effect of vanadium in titanium alloy, and be applied to aerospace field, thereby made aerospace industry obtain breakthrough progress.Along with developing by leaps and bounds of scientific and technological level, vanadium is more and more extensive in the application in non-steel field, and its scope has contained the various fields such as aerospace, chemistry, battery, pigment, glass, optics, medicine.
When vanadium and alloy plate strip cold rolling thereof, because elastic flattening makes the unit pressure of strip side portion very little, and the unit pressure at band middle part is very high.If adopt with pressure, increase and the remarkable lubricant increased of frictional coefficient, strip can produce very large edge extension and affect its planeness.Vanadium is when cold rolling, and along with the increasing of reduction in pass and roll speed are accelerated, surface smoothness can reduce, the hot sticky phenomenon of Here it is roll and rolled piece, and the small abrasion powder at this moment generated is attached on roll or material surface, makes plate surface coarse.When vanadium cold rolling (finish rolling), owing to laying particular emphasis on product surface quality, in the situation that meet plate shape, require, add less lubricant as far as possible.Therefore, be necessary to adopt the low viscosity that does not produce oil mark when annealing, low sulfur-bearing, high bearing capacity, there is the lubricant of good cooling, lubricated, clean, diffusion, thermal oxidation stability mineral oil simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide vanadium and the alloy plate strip cold-rolling lubricant thereof that a kind of hot sticky, when annealing of reducing roll and rolled piece do not produce oil mark, low viscosity, low sulfur-bearing.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt No. 15 total loss systems with oil as base oil, coordinate multiple composite additive, its each component and mass percent are:
| Component | Content (mass percent) |
| Base oil | 75%～85% |
| Anti-wear agent | 3.0%～5.0% |
| Oiliness improver | 10.0%～20.0% |
| Antioxidant preservative | 0.5%～1.2% |
| Oxidation inhibitor | 0.1%～0.3% |
| Kilfoam | 0.001%～0.003% |
| Non-emulsifying agent | 0.2%～0.5% |
Base oil is No. 15 total loss system oil.
Anti-wear agent is that the tritolyl phosphate of the mass ratio boric acid ester that is 50%～40% and 50%～60% is compound.
Oiliness improver is that dimeracid and 40%～50% the rapeseed oil of mass ratio 60%～50% is compound.
Antioxidant preservative is sulphur phosphorus brothers base zinc salt.
Oxidation inhibitor is N, the inferior Whitfield's ointment propylene diamine of N-bis-.
Kilfoam is dimethyl silicone oil.
Non-emulsifying agent is the polyethers macromolecular compound.
Vanadium of the present invention and alloy plate strip cold-rolling lubricant thereof can significantly reduce hot sticky the phenomenon of roll and rolled piece; Do not produce the low viscosity of oil mark, low sulfur-bearing when annealing; The lubricant that simultaneously there is good cooling, lubricated, clean, diffusion, thermal oxidation stability mineral oil.
