Abstract
The invention discloses a hot-rolling lubricant for hafnium and alloy plate strips thereof. According to the hot-rolling lubricant, polyinternalolefin 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 lubricant disclosed by the invention can be used for cooling, lubricating, cleaning, diffusing and lowering the zirconium adhesion degree of a rolling roller and lowering the friction coefficient, 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
Technical field
The invention belongs to hafnium and alloy plate strip hot-rolled 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.Being very useful due to the easy electron emission of hafnium, as being used as the filament of incandescent light, making 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 unwanted gas such as oxygen, nitrogen that hafnium getter can exist in removing system.
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.
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 hot rolling, can be convenient to better to carry out cold rolling.
Summary of the invention
The technical problem to be solved in the present invention be to provide one have cooling, lubrication, cleaning, diffusion and reduce roll glue zirconium degree, reduce frictional coefficient, be convenient to de-oiling, annealing and alkali pickling, reduce hafnium and the alloy plate strip hot-rolled lubricant thereof of the damage that strip surface adhering causes and the melanism avoiding the lubricant that may occur.
The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on poly-internal olefin, coordinate multiple composite additive, its each constituent mass percentage ratio is:
