摘　　要：为了解决滚筒式叶片加料回潮机的后室温度的过程能力指数较低的问题,对滚筒式叶片加料回潮机的电控系统进行了改进.后室温度由传统的PID控制改进为分段控制+传统PID控制,增加前室温度控制回路,补偿蒸汽回路由手动控制改进为自动控制.改进后应用结果表明,后室温度的过程能力指数从0.82提高到1.50,设备的预热时间也由40 min降低至20 min,年节约电能4 458 kW.h,节约蒸汽575 t.In view of the lower temperature process capability during the strips casing and cylinder conditioner＇s working,it＇s electric control system was improved.The chamber temperature control circu it from the traditional PID control to a sub-control＋traditional PID control,pre-chamber temperature control loop was added,the circuit compensation steam changes manual control from to automatic control.The result proves the temperature process capability index improves from 0.82 to 1.5,preheating time decreases from 40 min to 20 min,and it can save electric energy 4 458 kW and steam 575 t every year.
