加铝喂丝机新型自动控制系统的应用

Application of new automatic control system for aluminum wire feeder

针对炼钢工序中加铝系统的工艺及控制要求,基于西门子S7-300PLC,M440变频器及现场总线技术设计了喂丝机控制系统。同时使用工业以太网的通信方式将喂丝机的相关工艺数据传送到厂局域网,便于查询和监控。运行结果表明,该自动控制运行稳定,具有良好的准确性,快速性和即时性等。

According to the process and control requirements of the aluminum wire feeder, the control system was designed based on Siemens S7-300 PLC, M440 drive and fieldbus technology. Meanwhile by using industrial ethernet communication, the process data of the wire feeder would be sent to the plant LAN for easy query and monitoring. The running results showed that the automatic control ran stably and had the good accuracy, speedahility and immediacy etc.
