摘　　要：介绍了使用50 Hz/250 Hz双频淬火机床对一种锥形辊淬火的工艺。因淬火过程中感应器和辊子的间隙不断变化导致磁通效率也不断变化,故施加功率随辊子行程近似线性调整,使整个辊身达到一致的淬火温度。辊子经检测和使用,淬火硬度及淬硬层深度均符合技术要求,表明双频淬火技术能够实现锥形辊的淬火。Quenching process for a conical roller using 50 Hz/250 Hz dual frequency induction hardening machine was introduced. During quenching process, the space between the roller and the inductor is changed contiously that result in the magnetic flux efficiency continuously changed, so apphed power should be adjusted linearly with roller stroke, thus the quenching temperature of the roller can reach uniform. After detected and used, the hardness and hardened layer depth of the roller meet technical requirements, which show the double frequency quenching technology can accomplish quenching of conical roller.
