目前热处理电阻炉采用PID调节可控硅调功SR93温度控制系统,该系统对升温、均温及保温都能达到精确控制,而对降温速度无法控制。采用二次进排风方式,增加二次导流风道,控制进排风风量即可实现降温速度可控的目的。
At present, the heat treatment resistance furnace adopts the PID-controlled thyristor SR93 temperature control system, which can accurately control the temperature, the average temperature and the insulation, and can not control the cooling rate. Adopting the second intake and exhaust method to increase the second diversion duct and control the temperature of the exhaust air to control the cooling rate.
