金属工件热处理时淬火温度直接决定金属工件的硬度与强度,为了提高淬火时温度的精准度和稳定性,系统采用MSP430单片机为控制核心,铂热电阻作为温度采集元件,设计了中频淬火温度控制电路。通过改变逆变器IBGT管触发脉冲频率,来控制感应炉系统的功率,温度信号经调理电路处理直接送入单片机,经单片机处理判断发出触发脉冲,温度值由液晶LCD显示。实验测试表明,系统具有接线简单,输出频率可调,功率因数高,性能稳定等优点。

Hquenching temperatureeat treatment of metal workpieces directly determines the hardness and strength of the metal workpieces. To improve the precision and stability of the quenching temperature, the system uses MSP430 MCU as the control core and the platinum thermal resistor as the temperature acquisition element. A intermediate frequency quenching temperature control circuit is designed. It changes the IBGT inverter trigger pulse frequency for controlling the power of the induction furnace system. The temperature signals are directly sent to a single chip by the conditioning circuit. The SCM processes the temperature signals and creates trigger pulse. The temperature value is displayed on the LCD. The experimental results show that the system has the advantages of simple wiring, adjustable output frequency, high power factor, stable performance and the like.
