大型工件井式热处理炉控制系统研制

The Development of Pit Annealing Furnace Control System for Large Workpiece

针对大型工件井式热处理炉的工艺和控制要求,系统采用工控机配套组态软件作为上位主控设备,可编程逻辑控制器、PID调节器、智能电力监测仪、变频器、数字功率调节器、数字阀门控制器等组成下位设备,构成一种典型的中型DCS集散控制系统。该系统采用双机冗余技术,在满足热处理过程的工艺参数检测与全过程优化控制的同时,提高了大型工件热处理监控系统的可靠性和稳定性。

In order to satisfy technological parameter and control request of large pit annealing furnace,choose industrial PC as supervisory computer,choose programmable logistic controller,PID control instrument,intelligent electric instrument,transducer,digital thyristor power controller and digital valve controller as control computer.And these devices have made up of DCS system.The DCS system which adopt two equipment redundancy technology not only accomplish measurement of technics parameter and excellent contol of industrial process,but also improve reliability and stability of large workpiece heat treatment computer control system.
