CN103468360B - Cold rolling lubricating agent for finished product of nickel and nickel alloy sheet strip - Google Patents

Abstract

The invention discloses a cold rolling lubricating agent for a finished product of a nickel and nickel alloy sheet strip. 10# industrial white oil is used as base oil and is matched with various composite additives including an anti-wear agent, an oiliness agent, an anti-oxidant and anti-corrosive additive, an antioxidant, a non-emulsifying agent, an anti-foaming agent, a friction improver and the like. Low-viscosity, low-sulfur and low-aromatic-hydrocarbon mineral oil incapable of generating stains during annealing is used as the base oil, so that the cold rolling lubricating agent has favorable cooling, washing, lubricating and easy dispersing performances and can be used for reducing the bonding phenomenon of a roller and a rolled piece during finished product cold rolling and meeting the requirements for sheet shape and surface finish.

Description

Nickel and alloy plate strip finished product cold-rolling lubricant thereof

Technical field

The invention belongs to nickel and alloy plate strip finished product cold-rolling lubricant field thereof.

Background technology

Nickel, silvery white metal, fusing point 1455 DEG C, boiling point 2730 DEG C, density is 8.902g/cm ³.Nickel has good physical strength and ductility, infusibility.It can lose in high polish, and matter is hard, has magnetic and good plasticity-.The erosion resistance had, not oxidized in atmosphere, resistance to highly basic again.Nickel is the metal of a medium tenacity.Metallic nickel is mainly used in electroplating industry, the article of nickel plating are attractive in appearance, totally, not easily corrosion again.Superfine nickel powder, on chemical industry, conventional its makes hydrogenation catalyst.

Because nickel has good physical strength and ductility, infusibility is high temperature resistant, and there is very high chemical stability, the feature such as not to be oxidized in atmosphere, therefore be a kind of very important non-ferrous metal raw material, be used to manufacture stainless steel, High Nickel Steel and structural alloy steel, be widely used in the various military industrial manufacturing enterprises such as aircraft, radar, guided missile, tank, naval vessels, spaceship, reactor.In civilian industry, it is a large amount of for various machinery manufacturing industry that nickel often makes structure iron, duriron, high temperature steel etc.Nickel also can make beramic color and coating for protection against corrosion, and nickel cobalt (alloy) is a kind of permanent magnet material, is widely used in the fields such as electronic telecontrol, nuclear industry and ultrasonic technique.Nickel basic product has: nickel strap, nickel sheet, nickel plate, nickel rod, nickel bead, nickel foil, nickel dish, nickel bits, nickel electrode, sponge nickel, nickel goods, nickel rim charge, nickel angle nickel screen, electrolytic nickel, electroformed nickel, Foamed Nickel, pure nickel wire etc.

During finished product cold rolling, because elastic flattening makes the unit pressure of strip side portion very little, and unit pressure in the middle part of band is very high.The lubricant that frictional coefficient significantly increases according to increasing with pressure, strip can produce very large edge and extends and affect its planeness.Nickel 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 nickel finished product cold rolling (finish rolling), owing to laying particular emphasis on product surface quality, when meeting plate shape and requiring, add lubricant less as far as possible.Therefore, 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 be to provide a kind of have good cooling, cleaning, lubrication, easily diffusion performance, reduce finished product cold rolling time roll and the adherent phenomenon of rolled piece, the nickel that can meet plate shape and surface smoothness requirements and alloy plate strip finished product cold-rolling lubricant thereof.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 10 industrial white oils, coordinate multiple composite additive, its each component and mass percent thereof are:

Component	Content (mass percent)

Oiliness improver is the oleic acid oxalic acid ester of mass ratio 50% ~ 60% and the sulfuration Oleum Gossypii semen compound of 50% ~ 40%.

Antioxidant preservative is sulphur phosphorus Zhong Ji zinc salt.

Oxidation inhibitor is N-phenyl-a-naphthylamines.

Kilfoam is dimethyl silicone oil.

Non-emulsifying agent is amine and epoxy compounds condenses.

Friction improver is sulphur molybdenum phosphate.

Nickel of the present invention and alloy plate strip finished product cold-rolling lubricant thereof, adopt not produce when annealing the low viscosity of oil mark, low sulfur-bearing, low aromatic hydrocarbons mineral oil make base oil, there is the performance of good cooling, cleaning, lubrication, easily diffusion; When minimizing finished product is cold rolling, the adherent phenomenon of roll and rolled piece, meets plate shape and surface smoothness requirements.
