Abstract
The invention provides a lubricating agent for the hot rolling of tungsten and tungsten alloy plates and strips. The lubricating agent is characterized in that total loss system oil No.100 is used as base oil and is matched with multiple complex additives. The lubricating agent comprises an anti-wear agent, a friction modifying agent, an antioxidant and corrosion inhibitor, an anti-foaming agent, a demulsifying agent, a cleaning agent, a dispersing agent and the like. The lubricating agent has relatively high adsorption capacity, can be used for ensuring that a layer of uniformly continuous oil film is formed between a roller and a rolled piece, reducing the friction coefficient in a rolling process and alleviating the adhesion and coking between the rolled piece and the roller and has good lubrication, cooling, cleaning and thermal oxidation stability properties.
Description
Technical field
The invention belongs to tungsten and alloy plate strip hot-rolled lubricant field thereof.
Background technology
Tungsten, a kind of metallic element, belong to non-ferrous metal, is also typical rare metal, is national grand strategy resource.Steel Grey or silvery white, hardness is high, and fusing point is high, not corroded by air; Main application, for manufacturing filament and high speed cutting steel alloy, superhard mould, also for opticinstrument, has very important purposes.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 that special performance is arranged.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.
Tungsten and alloy plate strip hot rolling technology thereof require: the one, and the hot rolling Heating temperature, because tungsten and alloy thereof have very high fusing point, the equiaxed grain structures of high resistance to deformation and powder metallurgy slab porous, easily cause low-temperature brittle fracture; Therefore its rolling-cogging must be heated to very high temperature.The 2nd, hot rolling rate and hot rolling speed, due to tungsten and the alloy plasticity temperature range narrow, resistance to deformation is large, its general working rate need be after rolling, just in conjunction with repeatedly annealing and can complete, for anti-oxidation, and can boost productivity, under the condition allowed at mill capacity, should increase the general working rate between twice annealing as far as possible.Divide and mix at pass reduction, thereby too little meeting causes distortion can not go deep into the slab middle part, produce serious nonaffine deformation, cause rolled piece to open one's mouth and layering.Therefore, pass reduction must be large, especially the bloom pass working modulus.On roll speed, for boosting productivity and guaranteeing, desired finishing temperature usually adopt high-speed rolling.But, when cogging, for improving bite condition, with low speed rolling, for well, in the intermediate rolling stage, with the rolled piece attenuation, can improve roll speed.Require lubricant to there is higher adsorptive power, 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 ofly to be had higher adsorptive power, 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, reduces adhesion and the coking of rolled piece and roll and has better lubricated, cooling, cleaning and tungsten and the alloy plate strip hot-rolled lubricant thereof of the performance that thermooxidizing is stable.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt No. 100 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 | 75%～83% |
| Anti-wear agent | 5.0%～6.0% |

| Antioxidant preservative | 0.5%～1.5% |
| Kilfoam | 0.001%～0.005% |
| Non-emulsifying agent | 0.1%～0.5% |
| Purification agent | 3.0%～5.0% |
| Dispersion agent | 4.0%～6.0% |
Base oil is No. 100 oil for the total loss system.
Anti-wear agent is that tritolyl phosphate and 60%～50% the sulfide isobutene of mass ratio 40%～50% is compound.
Friction improver is that 124 Triazole lipid acid amine salt and 40%～50% the sulphur molybdenum phosphate of mass ratio 60%～50% is compound.
Antioxidant preservative is sulphur phosphorus fourth octyl group zinc salt.
Kilfoam is dimethyl silicone oil.
Non-emulsifying agent is amine and epoxy compounds condenses.
Purification agent is alkyl sodium salicylate.
Dispersion agent is that mono alkenyl succimide and 50%～40% the polyisobutene succinimide of mass ratio 50%～60% is compound.
Tungsten of the present invention and alloy plate strip hot-rolled lubricant thereof, have higher adsorptive power, 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.
