Description
Technical field
The present invention relates to a kind of axle of track section, axle sleeve processing units, especially relate to a kind of axle of track section, axle sleeve quenching processing units.
Background technology
At present, during steel alloy tempering, there is the phenomenon of second maximum value at 500 ~ 600 DEG C in hardness one tempering temperature relation curve.The cause of tempering secondary hardening, one is the precipitation of alloy martensite alloy carbide when high tempering, causes martenaging martempering secondary hardening; Two is secondary quenchings of retained austenite, changes martensite into when namely cooling after tempering.
In high quality steel, stability of retained austenite is comparatively strong, and less than 500 DEG C tempering do not change; Also do not undergo phase transition during 500 ~ 600 DEG C of tempering insulations, and generation secondary quenching changes martensite into when cooling.But secondary quenching marten siting also tempering (malleableize) must can drop into military service.Therefore, the secondary hardening ability of steel in fact only depends on the process of alloy martensite secondary hardening: the essence of precipitate and quantity.
At present, the rigid requirements of the track section of existing heavy-duty vehicle is very high, and the requirement for processing is more and more higher, and common track section is just through a temper, thus does not reach and improve track section with high rigid requirements.And be generally all difficult to process in the inner ring tempering of the axle sleeve of track section.
