大型H型钢高焦加压站系统的优化改造

Transformation of Gas Pressurization Station System for Large H Steel Production

大型H型钢高焦加压站系统主要是完成焦炉煤气和高炉煤气加压后外供给用户。该自控系统采用施耐德的QUANTUM系列PLC。高、焦炉煤气加压站共使用一台QUANTUM PLC控制,通过远程I/O方式连接两个机架,用Ethernet实现PLC与服务器之间的连接以及服务器与监控机之间的连接,服务器同时兼做监控机,完成全过程的顺序控制和回路控制,实现了生产工艺设备的自动启停及电气联锁保护、工艺生产过程的数据采集、数据处理等。

The gas pressurization station system for large H steel production is mainly to complete the supply of pressurized coke oven gas and blast furnace gas.The QUANTUM series PLC of Schneider is used in the automatic control system,and the coke oven gas compression station and the blast furnace gas compression station use a set of PLC control system,they are connected by the remote I/O mode,the communication between the PLC and the server is realized through the Ethernet,the server and the monitor computer use the same way to communicate.The server can be used as a monitor machine.The control way can realize sequence control and loop control,automatic start/stop and electric interlock protection,process data acquisition and processing,etc.
