Abstract

The invention relates to a hot-rolled lubricant for rhenium and alloy plate strips thereof. The lubricant is prepared by taking NO.150 oil for a total-loss system as base oil, and combining a plurality of composite additives including an anti-wear agent, an oiliness additive, a friction improver, an antioxidant and corrosion inhibitor, an anti-foaming agent, an anti-emulsion agent, a cleaning agent, a disperser and the like. The hot-rolled lubricant is high in adsorbability, a uniform and continuous oil film layer is guaranteed to form between a roll and a rolled piece; the friction coefficients in the rolling process can be reduced, the adhesion and coking of the rolled piece and the roll can be decreased, and the hot-rolled lubricant has better lubrication, cooling, cleaning and thermal oxidization stability properties.

Description

Rhenium and alloy plate strip hot-rolled lubricant thereof

Technical field

The invention belongs to rhenium and alloy plate strip hot-rolled lubricant field thereof.

Background technology

Rhenium: density 21.04g/cm ³, fusing point 3440 DEG C, boiling point 5627 DEG C.Lattice types hexagonal is intensive.Together, pure rhenium matter is soft, has good mechanical property for appearance and platinum.Current rhenium is widely used in modern industry all departments, main as petroleum industry and automotive industry catalyzer, petroleum reforming catalyst, electronic industry and space industry rhenium alloys etc.Rhenium is mainly used as the catalyzer of petroleum industry; Rhenium has very high electron emission capability, is widely used in wireless, TV and vacuum technique.Rhenium fusing point is very high, is a kind of main high temperature instrument material.The alloy of rhenium and rhenium also can make electrical tube element and ultrahigh-temperature well heater with evaporated metal.Wolfram rhenium heat electric couple does not also soften at 3100 DEG C, and the rhenium adding 25% in tungsten or molybdenum alloy can increase ductility; Rhenium is used as high temperature coating use on rocket, guided missile, and the instrument of spaceship and high-temperature component such as thermoshield, arc-over, electric contactor etc. all need rhenium.Rhenium metal and alloy thereof can Fountain pen nib processed and pyrometer couples; Catalyzer is made in the chemical industry such as dehydrogenating alcohol, synthetic ammonia; The alloy of rhenium-containing can be high temperature resistant; Also be used for manufacturing the shell of electric lamp filament, man-made satellite and rocket, the protective shield etc. of reactor.Because the existence of rhenium disperses, expensive, practical application waits exploitation.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind ofly has higher adsorptive power, ensures between roll and rolled piece, form one deck uniformly continous oil film; Reduce the frictional coefficient in the operation of rolling, reduce adhesion and the coking of rolled piece and roll, and there is rhenium and the alloy plate strip hot-rolled lubricant thereof of the performance that better lubrication, cooling, cleaning and thermooxidizing are stabilized.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 150 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	5.0%～6.0%
		Oiliness improver	6.0%～7.0%
Antioxidant preservative	0.5%～1.0%

Kilfoam	0.001%～0.003%
		Non-emulsifying agent	0.1%～0.5%
Purification agent	3.0%～4.0%
		Dispersion agent	3.0%～4.0%
Friction improver	1.0%～2.0%

Base oil is No. 150 total loss system oil.

Anti-wear agent is the tritolyl phosphate of mass ratio 60% ~ 50% and the aminothio ester compound of 40% ~ 50%.

Oiliness improver is Uniphat A60.

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 polyisobutene succinimide.

Friction improver is sulphur molybdenum phosphate.

Rhenium of the present invention and alloy plate strip hot-rolled lubricant thereof, adopt oil based on No. 150 total loss system oil, coordinate multiple composite additive.Comprise anti-wear agent, oiliness improver, friction improver, antioxidant preservative, kilfoam, non-emulsifying agent, purification agent, dispersion agent etc.Lubricant has higher adsorptive power, ensures between roll and rolled piece, form one deck uniformly continous oil film; 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.
