Tthis paper presents the structure of preheating the egative-pole steel rod, the hardware of which consists of the pre-heating system, the roller converting systems, and the air values controlling system. the total power of process requirement achieving the preheating system is obtain through the thoroughly theoretic calculation. The software is based on the Programming Logic Con-troller(PLC) for process controlling automation. The combination of fuzzy control and PID controllers is exploited to control the temperature of the electric heating furnace. The temperature controller can not only show the fuzzy control’s good robustness, good dynamic response, short rising time and small over-regulation and so on, but also show good dynamic tracking of PID and steady precision. For all above, the system reaches the designing target and performance requirement.
