Abstract

The invention discloses a hot rolling lubricating agent for a nickel and nickel alloy sheet strip. 100# 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, an anti-foaming agent, a non-emulsifying agent, a friction improver and the like. The hot rolling lubricating agent is prepared from refined mineral oil with extremely-low sulfur content and has favorable load resistance, depressurization and safety performances; meanwhile, the technological lubricating performance can be improved, the strength of an oil film in a deformation region can be enhanced, the friction coefficient can be reduced, and the component and the performance are stable; the phenomenon of thermally bonding a rolled piece and a roller is not easily caused; the hot rolling lubricating agent has favorable cleaning, dispersing and flushing performances and has no corrosion to metal and equipment, no toxicity and no pungent smell.

Description

Nickel and alloy plate strip hot-rolled lubricant thereof

Technical field

The invention belongs to a kind of nickel and alloy plate strip hot-rolled 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 is often used as hydrogenation catalyst by chemical industry.

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.

Nickel and alloy thereof must be cleared up ingot casting before hot rolling.Before hot rolling cogging, blank must be heated with low-sulfur fuel.In hot rolling cogging processing, pass deformation should be as far as possible little, to avoid occurring intergranular crack in cast structure.Processing after hot rolling cogging, allows larger hot-work pass deformation.Adopt the extremely low refined mineral oil of sulphur content can be formulated into and there is good load resistance, supporting capacity, pressure and stability; Also can improve technological lubrication performance, increase oil film strength in distorted area, reduce frictional coefficient, stable performance.Not easily occur hot sticky, corrosion-free, toxicity and irritating smell.

Summary of the invention

The technical problem to be solved in the present invention is to provide one and has good load resistance, pressure property and stability; Meanwhile, technological lubrication performance can be improved, increase oil film strength in distorted area, reduce frictional coefficient, composition and stable performance; Not easily there is rolled piece and roll thermal adhering phenomenon, there is good clean, diffusion and flushing performance; To metal and equipment corrosion-free, nontoxicity, the nickel had no irritating odor and alloy plate strip hot-rolled lubricant thereof.

The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 100 industrial white oils, coordinate multiple composite additive, its each component and mass percent thereof are:

Component	Content (mass percent)
