Abstract

The invention relates to a cold-rolling lubricant for lead and lead alloy sheet strips, which uses 5# total loss system oil as base oil matched with multiple compounded additives. The lubricant comprises an antiwear additive, an oily agent, an antioxidant, a metal passivator, an antifoam agent, a demulsifying compound and the like. The cold-rolling lubricant provided by the invention can effectively perform lubrication, cleaning and cooling, can effectively lower the adhesion phenomenon between the roller and the rolled piece, and reduces the damage caused by sheet strip surface adhesion.

Description

Tin and alloy plate strip cold-rolling lubricant thereof

Technical field

The invention belongs to tin and alloy plate strip cold-rolling lubricant field thereof.

Background technology

Tin, metallic element, a kind of low melting point metal element of white gloss of bit bluish is argenteous soft metal, and proportion is 7.3g/cm ³, fusing point only has 232 DEG C, puts in coal dust ball stove the liquid that just can be melt into as mercury into.Tin is very soft, can cut it with pocket knife.The chemical property of tin is very stable, not easily oxidized at normal temperatures; Therefore, it often keeps silver-colored glittering gloss.Tin is nontoxic, and plasticity-is strong and ductility is very poor, disconnected once drawing, and can not pull into filament.It can have various process of surface treatment, the product of multiple style can be made, remain the indispensable crucial rare metal of modern industry, be known as " industrial monosodium glutamate ", be widely used in the industries such as electronics, information, electrical equipment, chemical industry, metallurgy, building materials, machinery, food product pack.

The resistance to deformation of usual tin and alloy thereof increases with rolling reduction and increases, and should select effective lubricant and lubricating method, carry out lubricating, clean, cool and reducing roll and rolled piece adherent phenomenon, reduces the damage that strip surface adhering causes.Tin is when cold rolling, and along with the increasing of reduction in pass and roll speed are accelerated, surface smoothness can reduce, the hot sticky phenomenon of Here it is roll and material, and the small abrasion powder at this moment generated is attached to roll or material on the surface, makes plate surface coarse.When sheet tin strap cold rolling, be constant in major control means with rolled metal flow, if simple tension control, sheet material will be broken.Existing comprehensive detection and control equipment; When this milling train work, be rolled and keep tensioning between roll, not lax tenesmus; Owing to laying particular emphasis on product surface quality, when meeting plate shape and requiring, add lubricant less as far as possible.To use, the mineral oil lubricant not producing the low viscosity of oil mark, low sulfur-bearing, low aromatic hydrocarbons when annealing should be adopted.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of can effectively carrying out and lubricates, cleans, cools and reduce roll and rolled piece adherent phenomenon, reduces tin and alloy plate strip cold-rolling lubricant thereof that strip surface adhering causes damage.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 5 total loss system oil, coordinate multiple composite additive, its each component and mass percent thereof are:

Component	Content (mass percent)
		Base oil	85%～90%

Anti-wear agent	3.0%～5.0%
		Oiliness improver	3.0%～5.0%
Oxidation inhibitor	0.2%～0.5%
		Metal passivator	2.0%～5.0%
Kilfoam	0.001%～0.005%
		Non-emulsifying agent	0.1%～0.3%

Base oil is No. 5 total loss system oil.

Anti-wear agent is the borate of mass ratio 50% ~ 40% and single sulfo-normal-butyl phosphoric acid ester compound of 50% ~ 60%.

Oiliness improver is plam oil.

Oxidation inhibitor is 2,6 ditertiary butyl p cresol.

Metal passivator is thiadiazoles derivative.

Kilfoam is dimethyl silicone oil.

Non-emulsifying agent is polyethers macromolecular compound.

Tin of the present invention and alloy plate strip cold-rolling lubricant thereof, can effectively carry out lubricating, clean, cool and reduce roll and rolled piece adherent phenomenon, reduces the damage that strip surface adhering causes.
