Abstract
The invention discloses a cold-rolling lubricant for hafnium and alloy foil materials thereof. According to the cold-rolling lubricant, 7# industrial white oil adopted as base oil is compounded with various additives including an anti-wear agent, an oiliness agent, an anti-oxidant preservative, an anti-oxidant, an anti-foaming agent, an anti-creaming agent, a metal deactivator and a friction modifier. According to the invention, refined mineral oil with extremely low sulfur content is mixed into a lubricant which has good load resistance, depression and stability, and does not generate annealing stains; meanwhile, the cold-rolling lubricant can be used for improving the process lubricating performance, increasing the oil film strength in a deformed area and lowering the friction coefficient, is stable in composition and performance, does not generate an adhesion phenomenon of a rolling piece and the rolling roller, has cleaning and flushing performances, and is free from corrosion to metals and equipment, non-toxic and free from pungent smell.
Description
Technical field
The invention belongs to hafnium and alloy foil cold-rolling lubricant field thereof.
Background technology
Hafnium is silver-gray glossy metal, fusing point 2227 DEG C, boiling point 4602 DEG C, density 13.31g/cm
3; Metal hafnium has higher neutron death ability.The purposes of hafnium: be very useful due to its easy electron emission (as being used as the filament of incandescent light).As the negative electrode of X-ray tube, the alloy of hafnium and tungsten or molybdenum is used as the electrode of high-voltage discharge tube.Hafnium can be used as the getter of a lot of inflation system.The undesirable gas such as oxygen, nitrogen that hafnium getter can exist in removing system.
The purposes of hafnium is the control rod making the nuclear reactor in addition.Pure hafnium has plasticity-, easily processing, high-temperature-resistant and anti-corrosion, is nuclear industry important materials.The thermal neutron capture cross section of hafnium is large, is comparatively ideal neutron absorber, can makes control rod and the protector of reactor.Hafnium powder can make the thruster of rocket.Electrical equipment industry can manufacture the negative electrode of X-ray tube.The alloy of hafnium can make the forward position protective layer of the aircraft that rocket nozzle and gliding type are reentried.By cold rolling, the good sheet material of surface quality can be obtained.
Hafnium is similar to the chemical property of zirconium, all has good erosion resistance, does not corrode by general soda acid; Be soluble in hydrofluoric acid; Can chemical combination direct with the gas such as oxygen, nitrogen under high temperature.Metal hafnium moderate strength, erosion resistance is good, and neutron absorption capability is high, in a large number for nuclear industry; Hafnium can generate multiple alloy, also can make the surface-coating of base metal.
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, does not produce annealing stain; Meanwhile, improve technological lubrication performance, increase oil film strength in distorted area, reduce frictional coefficient, composition and stable performance; Not easily there is rolled piece and the hot sticky clean phenomenon of roll, have clean and rinse performance; To metal and equipment corrosion-free, nontoxicity, the hafnium had no irritating odor and alloy foil cold-rolling lubricant thereof.
The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 7 industrial white oils, coordinate multiple composite additive, its each component and mass percent thereof are:
