Abstract

A kind of tungsten and alloy plate strip cold-rolling lubricant thereof, adopt oil based on No. 46 total loss system oil, coordinate multiple composite additive.Comprise anti-wear agent, oiliness improver, antioxidant preservative, kilfoam, metal passivator, purification agent, dispersion agent etc.This lubricant has higher absorption, diffusion and supporting capacity, 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.

Description

Tungsten and alloy plate strip cold-rolling lubricant thereof

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, belonging to non-ferrous metal, is also rare metal, is the grand strategy resource of country.Tungsten is typical rare metal.Hardness is high, and fusing point is high, not by air erosion under normal temperature; 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 material, specific alloy, new function material and organometallic compound etc. all need the tungsten using special performance.Though consumption is little, most important, lacking it can not.Thus contemporary mechanics of communication, robot calculator, aerospace exploitation, medical and health, sensitive materials, photoelectric material, energy and material and catalystic material etc. are widely used in.Relate to mine, metallurgy, machinery, building, traffic, electronics, chemical industry, light industry, weaving, military project, space flight, science and technology, each industrial circle.

Tungsten cold rolled sheet requires higher for product surface quality, but 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 material deformation drag is larger on the other hand, and can make full use of Plastic Deformation and mill capacity, the general working rate between twice annealing can reach more than 50%; Pass reduction is generally descending; Tension force can ensure that rolled piece is steadily nipped, and reduces rolling pressure and improves general working rate and pass reduction, and can control thickness of slab, eliminate the defect such as waviness, backfin produced in the course of processing.In the operation of rolling, tension force should change with the change of rolling load, roll shape and roll speed matches.Therefore, require that lubricant has higher absorption, diffusion and supporting capacity, ensure 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.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind ofly has higher absorption, diffusion and supporting capacity, 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 tungsten and the alloy plate strip cold-rolling 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. 46 total loss system 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 total loss system oil.

Anti-wear agent is the sulfide isobutene of mass ratio 70% ~ 80% and the tritolyl phosphate compound of 30% ~ 20%.

Oiliness improver is the dimeracid of mass ratio 60% ~ 70% and the dioctyl sebacate compound of 40% ~ 30%.

Antioxidant preservative is phosphoric acid fourth octyl group zinc salt.

Kilfoam is dimethyl silicone oil.

Metal passivator is the petroleum sodium sulfonate of mass ratio 60% ~ 70% and the benzotriazole compound of 40% ~ 30%.

Purification agent is the low alkali value petroleum sodium sulfonate of mass ratio 60% ~ 50% and the high base number petroleum sodium sulfonate compound of 40% ~ 50%.

Dispersion agent is the diene base succimide of mass ratio 60% ~ 50% and the polyisobutene succinimide compound of 40% ~ 50%.

Tungsten of the present invention and alloy plate strip cold-rolling lubricant thereof, have higher absorption, diffusion and supporting capacity, 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.
