Description
Technical field
The present invention relates to a kind of bearing and Technology for Heating Processing thereof, concrete this say be a kind of wind power plant bearing and
Its Technology for Heating Processing.
Background technology
Wind power bearing is a kind of special bearing, uses bad environments, high maintenance cost, it is desirable to high life.Wind power bearing
Typically all containing chromium in composition, the increase of chromium can improve heat treatment performance, to improve quenching degree, structural homogenity, tempering stable
Property, rustless property and the grinding performance of steel can be improved again；But when chromium content is higher, after quenching, increase retained austenite in steel,
Reduce hardness and dimensional stability, increase the inhomogeneities of carbide, reduce impact flexibility and the fatigue strength of steel.It addition, it is existing
Some wind power plant bearings are shorter for service life, do not have antistatic behaviour, absorb thermal insulation and surface water repellency, uncomfortable
It is combined under bad environments and harsh conditions use.
Summary of the invention
The technical problem to be solved is, how to improve wind power plant bearing rustless property and grinding
While performance, do not reduce impact flexibility and the fatigue strength of bearing；To be solved by this invention another technical problem is that: as
In the service life of what increase wind power plant bearing, make it have antistatic behaviour simultaneously, absorb thermal insulation and surface water repellent
Property.
The present invention solves the technical scheme of above technical problem:
A kind of wind power plant bearing, its mass percent composition is: C:0.93-0.95%, Cr:1.61-1.63%, Si:
0.12-0.15%, Mn:0.55-0.57%, Ni:4.66-4.68%, Mo:0.02-0.05%, Als:0.015-0.035%, S≤
0.005%, P≤0.007%, N≤0.007%, surplus is Fe；
Its Technology for Heating Processing is: (i) heating: by bearing heating to 615-617 DEG C, and be incubated 45-47min；(ii) cooling: use wind
After bearing is accelerated to be cooled to 531-534 DEG C by the cold cooldown rate with 15-17 DEG C/s, then air cooling is to room temperature；The most once tempering: will
After bearing heating is tempered 45-47min to 575-577 DEG C, treats temperature 13-15s, make bearing temperature homogenization, afterwards with 38-40 DEG C/s
Cooldown rate accelerate to be cooled to 441-444 DEG C after, then air cooling is to room temperature；(iv) double tempering: by bearing heating to 603-605 DEG C
After tempering 67-69min, air cooling is to room temperature.
Key chemical components content of the present invention limits and the effect played of Technology for Heating Processing and having the beneficial effect that
Containing Cr:1.61%-1.63% in the present invention, content is higher, can improve heat treatment performance, improve quenching degree, tissue all
Even property, temper resistance, can improve again rustless property and the grinding performance of steel；But when chromium content is higher, after quenching, increase steel
Middle retained austenite, reduces hardness and dimensional stability, increases the inhomogeneities of carbide, reduces impact flexibility and the fatigue of steel
Intensity；The present invention passes through heat treatment, it is possible to avoids harmful element Grain Boundary Segregation and thick Carbide Precipitation, thus prevents from reducing axle
The impact flexibility held and fatigue strength.
Containing Ni:4.66-4.68% in the present invention, it is possible to stable austenite phase, the quenching degree that improves, reduction ductile-brittle transiton temperature
Degree also can improve deformation performance；Coordinate the present invention Technology for Heating Processing, can with thinning microstructure and obtain lath bundle tissue add lack
The rotary austenite that amount (volume fraction 1-5%) is stable, this line and staff control has higher-strength and good impact toughness.Ni content
Too low, rotary austenite stability declines, and impact flexibility is difficult to ensure that；Ni too high levels then makes cost increase.
Step of the present invention (ii) in, use air-cooled acceleration to be cooled to 531-534 DEG C, in process air cooler subsequently γ-Fe with
Trimming mechanism is changed into α-Fe, obtains the ferritic structure of lath bundle form, and C atom then can spread, at lath circle
Or be enriched with on lath bundle circle or exist with M-A constituent element interstitial atom form, this tissue and Elemental redistribution state are more beneficial for follow-up
The formation of rotary austenite in heat treatment, accelerates cooling and can also avoid under the conditions of high temperature slow cooling harmful element Grain Boundary Segregation and thick
Big Carbide Precipitation, beneficially low-temperature flexibility.
Step (iii) in, after 575-577 DEG C of tempering 45-47min, treat temperature 13-15s, make bearing temperature homogenization, afterwards with
After the cooldown rate of 38-40 DEG C/s is accelerated to be cooled to 441-444 DEG C, then air cooling is to room temperature；Rotary austenite is at lath circle or plate
Formed on Tiao Shu circle, and in insulating process, be enriched with alloying element further to improve stability；Ferrite lath bundle is in insulation
During then reply, the harmful element in ferrite is also discharged in rotary austenite simultaneously, thus improves matrix
Energy.
Step (iv) in, be heated to 603-605 DEG C tempering 67-69min after air cooling to room temperature, it is possible in the premise of proof strength
Under make the rotary austenite abundant alloying element of enrichment, make few net carbide, make tissue be more uniformly distributed, it is possible to keep structure
Stable, further enhance contact fatigue strength and impact flexibility.Because can become due to carbide liquid-extraction during bearing heating
Hard and crisp, its hazardness is identical with brittle inclusion, and net carbide reduces the impact flexibility of steel, and is allowed to uneven microstructure
Degree.
In order to solve second technical problem, the outer surface of wind power plant bearing of the present invention posts composite membrane, multiple
Closing film and include PTFE film, the one side in PTFE film scribbles cross-linked binder glue, and the another side in PTFE film is coated with nanometer solution, axle
