Background technology
Macrotype axes series parts are in machinery industry using relatively broad.Such as the wind power principal axis in wind power industry is
The Typical Representative of macrotype axes series parts.In wind-driven generator, wind power principal axis is to connect wind wheel and gear-box or the weight of generator
Vital part is wanted, main raw material(s) is steel ingot, becomes master after three master operations such as forging and pressing, be heat-treated, finishing and make
Axis, heat treatment step therein is more crucial, and the quality of its thermal treatment quality directly influences final product quality.
There are problems with for the heat treatment of the macrotype axes series parts such as existing wind power principal axis：
First, part carries out Cooling Quenching after the high-temperature heating of heat-treatment furnace, it is necessary to be lifted into cooling bay, part
During heat-treatment furnace is out lifted into cooling bay again, acted on be subject to moving air, surface temperature meeting slow cooling, if gone out
Existing surface temperature is less than critical hardening temperature, and the quenching hardness on surface can be caused not reach design requirement, cause product mechanicalness
It can decline.
Second, during part enters cooling bay, the axle body of part cannot be immersed in the water at the same time, and the lower part of part is first
Cooling water is contacted, then is gradually immersed into by middle part and top in water.Since the macrotype axes series parts such as wind power principal axis different parts exist
The time difference of quenching, expand with heat and contract with cold and be out of step, being easy to cause the macrotype axes series parts such as wind power principal axis surface even inside should
Power distribution deteriorates, and the situation of this surface even internal stress distribution state deteriorating can directly result in the production of part crack
