PLC在钢包底吹氩系统中的应用

Application of PLC in the System for Blowing Argon at Bottom of Molten Steel Container

分析了炼钢工艺中氩流量控制难的原因,提出采用高可靠性的可编程序控制器作为控制器,应用模糊控制方案和PCM脉冲编码技术,对钢包吹氩流量进行智能精确地控制。该系统已在数家炼钢厂投入使用。

The mater of controlling argon flux on steel-making technics was analysed, The high reliability PIE controller was introduced, scheme being based upon fuzzzy control theory and Pulase Code Modulation were adopted. Thus the argon flux for molten steel container were controlled automationally and accurately. The intelligent control system has been used by several steelworks.
