CN103627478B - Warm-rolling lubricant for zirconium and alloy plate strips thereof - Google Patents

Abstract

The invention discloses a warm-rolling lubricant for zirconium and alloy plate strips thereof. According to the warm-rolling lubricant, 68# oil for a total-loss system, which is adopted as base oil, is compounded with various composite additives including an anti-wear agent, an oiliness agent, a friction modifier, an anti-oxidant preservative, an anti-foaming agent, an anti-creaming agent, a cleaning agent, a dispersant and a metal passivator. The warm-rolling lubricant disclosed by the invention can be used for effectively cooling, lubricating, cleaning, diffusing and lowering the zirconium adhesion degree of a rolling roller, and is convenient for degreasing, annealing and alkali pickling, so that damages caused by plate strip surface adhesion can be reduced and a possible blacking phenomenon of the lubricant is avoided.

Description

Zirconium and alloy plate strip warm-rolling lubricant thereof

Technical field

The invention belongs to zirconium and alloy plate strip warm-rolling field of lubricant thereof.

Background technology

Zirconium, a kind of metallic element is one of argenteous refractory metal, in light grey.Density 6.49g/cm ³, fusing point 1852 ± 2 DEG C, boiling point 4377 DEG C.Be applied to nuclear industry and be used as anti-corrosion chemical materials etc. at high temperature under high pressure.

Zirconium and alloy thereof have two distinguishing features in rolling: one is that chemical property is relatively more active, so that in the operation of rolling, especially in warm rolling process, easy and surrounding environment produces reacts and causes pollution, reduces processing characteristics; Two is rolls of very easily adhering.Because zirconium and alloy thereof have the character of tool and mould of very easily adhering, in zirconium and the alloy material operation of rolling thereof, effective lubricant and lubricating method should be selected, carry out cooling, lubricate, clean, spread and reduce roll and glue zirconium degree, reduce frictional coefficient, be convenient to de-oiling, annealing and alkali pickling, reduce the damage that strip surface adhering causes and the melanism avoiding the lubricant that may occur.

Summary of the invention

The technical problem to be solved in the present invention be to provide a kind of there is cooling, lubrication, cleaning, diffusion and reduce that roll glues zirconium degree, reduces frictional coefficient, is convenient to de-oiling, annealing and alkali pickling, the zirconium reducing the damage that strip surface adhering causes and the melanism avoiding the lubricant that may occur and alloy plate strip warm-rolling lubricant thereof.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 68 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	6.0%～8.0%
		Oiliness improver	5.0%～6.0%
Antioxidant preservative	0.5%～1.0%
		Kilfoam	0.001%～0.003%

Non-emulsifying agent	0.2%～0.3%
		Metal passivator	0.5%～1.0%
Dispersion agent	5.0%～6.0%
		Purification agent	4.0%～5.0%
Friction improver	2.0%～3.0%

Base oil is No. 68 total loss system oil.

Anti-wear agent is the oildag (aquadag) of mass ratio 70% ~ 80% and the dioctyl sebacate compound of 30% ~ 20%.

Oiliness improver is the lard of mass ratio 70% ~ 60% and the tetradecyl alcohol compound of 30% ~ 40%.

Antioxidant preservative is sulphur phosphorus fourth octyl group zinc salt.

Kilfoam is dimethyl silicone oil.

Non-emulsifying agent is polyethers macromolecular compound.

Metal passivator is dialkyl diphenylamine.

Dispersion agent is the polyisobutene succinimide of mass ratio 80% ~ 70% and the mono alkenyl succimide compound of 20% ~ 30%.

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

Friction improver is common Vaseline.

Zirconium of the present invention and alloy plate strip warm-rolling lubricant thereof, adopt oil based on No. 68 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, metal passivator.Can effective cooling, lubrication, cleaning, diffusion and reduce roll and glue zirconium degree, reduce frictional coefficient, be convenient to de-oiling, annealing and alkali pickling, reduce the damage that strip surface adhering causes and the melanism avoiding the lubricant that may occur.
