槽下和炉顶上料自动控制系统通过一套S7-400PLC完成,放在槽下主控室。系统配一台工控机做为人机接口操作站。热风炉、布袋除尘及高炉本体各种温度、压力、流量及电动阀门信号进入S7-400PLC,放在工长值班室。系统配有三台工控机做为人机接口操作站,其中高炉本体及布袋除尘操作站都可以转换至上料监控窗口,监视上料自动系统,并通过锁下密封来控制炉顶上料。PLC、交换机、操作站之间通过光纤电缆连接。
Slot and furnace top loading automatic control system through a set of S7-400PLC completed on the tank under the control room. System with a IPC as a man-machine interface operation station. Blast furnace, bag dust and blast furnace body temperature, pressure, flow and electric valve signal into the S7-400PLC, on duty duty room. The system is equipped with three industrial control computer as a man-machine interface operation station, in which the blast furnace body and the bag dust removal operation station can be switched to the loading monitoring window to monitor the feeding automatic system and control the top loading by locking the sealing. PLC, switches, operating stations connected by fiber optic cable.
