摘　　要：为了充分利用各种煤气资源,保持煤气压力稳定,宣钢基于DCS与变频器设计了煤气加压混气站控制系统。DCS系统整合不同公司的总线设备,实现了对煤气压力的自动控制。功能可靠的控制系统使整个加压混气站设备安全可靠,运行稳定。To make the best of various gas resources and keep gas pressure stable, Xuanhua Iron ＆ Steel Co designed the control system forthe gas pressuring and mixing station based on DCS and frequency converter. The DCS system integrated bus devices of different companies to control gas pressure automatically. The control system with reliable functions made the whole devices in the station safe, reliable and stable operation.
