Continuously Sintering Furnace Temperature Control System Based on Intelligent PID Adjustment

To meet the demands of temperature control accuracy in continuously sintering furnace with multiple hearths, this system was constituted with PC, XMT624 and solid state relay for temperature field control. According to the characteristics of heating process, temperature inertia, lag of sintering furnace, adopted intelligent PID algorithm to achieve the large-scale temperature adjustments, it overcomes the limitation of traditional PID control. Through online setting intelligent instrument unit realtimely, the system achieves the target of temperature control accuracy in 2degC per thousand centigrade.
