摘要
通过对8620H齿轮锻件等温正火中的加热温度、冷却速度、冷却时间和等温温度的分析,使锻件等温正火后获得合格的硬度和金相组织。
The heating temperature,cooling rate,cooling time and isothermal temperature of the isothermal normalizing for 8620H gear forgings were analysed.The eligible hardness and microstructure of gear forgings after isothermal normalizing were obtained.
