Abstract
The invention relates to a cold rolling lubricating agent for tungsten and tungsten alloy plates and strips. No. 46 full-loss system oil is adopted as base oil, a variety of compound additives are used for matching, and the compound additives comprise an anti-wear agent, an oiliness agent, an antioxidant preservative, a defoaming agent, a metal deactivator, a detergent, a dispersant and the like. The lubricating agent has higher adsorption, dispersion and bearing capacities and can be used for ensuring the formation of a layer of uniform and continuous oil film between a roller and a rolled piece, reducing the friction coefficient during the rolling process, reducing adhesion and coking of the rolled piece and the roller and realizing better lubrication, cooling, cleaning and thermal oxidation stabilization performances.
Description
Technical field
The invention belongs to tungsten and alloy plate strip cold-rolling lubricant field thereof.
Background technology
Tungsten, a kind of Steel Grey or argenteous metallic element, belong to non-ferrous metal, is also rare metal, is national grand strategy resource.Tungsten is typical rare metal.Hardness is high, and fusing point is high, not corroded by air; Main application is for manufacturing filament and high speed cutting steel alloy, superhard mould, and also for opticinstrument, purposes is very important.It is the important component part of contemporary high technology novel material, and a series of electron optics materials, specific alloy, new function material and organometallic compound etc. all need to use the tungsten of special performance.Though consumption is little, most important, lacking it can not.Thereby be widely used in contemporary mechanics of communication, robot calculator, aerospace exploitation, medical and health, sensitive materials, photoelectric material, energy and material and catalystic material etc.Relate to mine, metallurgy, machinery, building, traffic, electronics, chemical industry, light industry, weaving, military project, space flight, science and technology, each industrial circle.
The tungsten cold rolled sheet requires higher for product surface quality, but the work hardening phenomenon can be more serious.Therefore, select suitable general working rate and pass reduction particularly important.Product specification is less on the one hand, and the material deformation drag is larger on the other hand, can take full advantage of Plastic Deformation and mill capacity, and the general working rate between twice annealing can reach more than 50%; Pass reduction is generally descending; Tension force can guarantee that rolled piece steadily nips, and reduces rolling pressure and improves general working rate and pass reduction, and can control thickness of slab, eliminates the defects such as the waviness that produces in the course of processing, backfin.In the operation of rolling, tension force should change with variation, the roll shape of rolling load and roll speed matches.Therefore, require lubricant to there is higher absorption, diffusion and supporting capacity, guarantee to form the even continuous oil film of one deck 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.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of have higher absorption, diffusion and supporting capacity, guarantees to form the even continuous oil film of one deck 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 tungsten and the alloy plate strip cold-rolling lubricant thereof of better lubricated, cooling, cleaning and the stable performance of thermooxidizing.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt No. 46 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 | 70%～78% |
| Anti-wear agent | 5.0%～8.0% |
| Oiliness improver | 7.0%～8.0% |
| Antioxidant preservative | 0.5%～1.0% |
| Kilfoam | 0.001%～0.005% |
| Metal passivator | 0.5%～1.5% |
| Purification agent | 3.0%～5.0% |
| Dispersion agent | 5.0%～8.0% |
Base oil is No. 46 oil for the total loss system.
Anti-wear agent is that sulfide isobutene and 30%～20% the tritolyl phosphate of mass ratio 70%～80% is compound.
Oiliness improver is that dimeracid and 40%～30% the dioctyl sebacate of mass ratio 60%～70% is compound.
Antioxidant preservative is phosphoric acid fourth octyl group zinc salt.
Kilfoam is dimethyl silicone oil.
Metal passivator is that petroleum sodium sulfonate and 40%～30% the benzotriazole of mass ratio 60%～70% is compound.
Purification agent is that low alkali value petroleum sodium sulfonate and 40%～50% the high base number petroleum sodium sulfonate of mass ratio 60%～50% is compound.
Dispersion agent is that diene base succimide and 40%～50% the polyisobutene succinimide of mass ratio 60%～50% is compound.
Tungsten of the present invention and alloy plate strip cold-rolling lubricant thereof, have higher absorption, diffusion and supporting capacity, guarantees to form the even continuous oil film of one deck 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.
