基于 PLC 的高炉上料自控系统设计 I 基于 PLC 的高炉上料自控系统设计摘要本设计介绍了西门子 S7-200 PLC 在炼铁高炉上料料控制系统中的运用,通过西门子S7-200PLC 与高炉上料系统的结合,设计出可编程序控制器的控制装置,基本上完成了 120m 3高炉供料电气控制系统的硬件设计。实现了布料(槽上)和槽下卷扬的实时控制和生产过程自动化的目的。基于 PLC 的高炉上料自控系统的设计,提高了高炉上料控制系统的自动化水平、可靠性,实现了上料系统的实时监控和灵活方便。具有一定的参考应用价值。关键词: 可编程序控制器高炉上料系统自动控制基于 PLC 的高炉上料自控系统设计 II PLC- BASED AUTOMATIC CONTROL SYSTEM OF BLAST FURNACE DESIGN ABSTRACT The S7-200 PLC of pany was essfully applied in the control system of the feed-in the raw materials of the blast furnace. Siemens S7-200 bine with blast furnace charging system,from a scheme of control device of programmable controller,finish the hardware design of electrical control system of120m 3 blast furnace material realized the purpose of the realtime control of material providing and production process automation under the through and rise. Have used PLC in the design,There isa growing interest for the application of PLC and works in the field of industrialautomation. The automatic function and reliability of the feeding system in blast furnace are improved by the realtime monitoring is realized and the position can be easily made.
