沉没炉顶吹熔炼铅自动控制系统设计

DESIGN ON AUTOMATIC CONTROL SYSTEM OF LEAD SMELTING BY SANK FURNACE TOPBLOWING

沉没炉顶吹熔炼铅系统,采用了富氧顶吹氧化熔炼工艺,应用PLC和工业控制计算机的典型结构,实现对炉内成分、温度、风量、管道气体流量、含氧量浓度进行实时检测及显示监控,根据含氧浓度调节进氧量、空气鼓入量,保证氧气浓度稳定在工艺要求的范围内。

For the sunk furnace topblowing of lead smelting system,the oxygen top-blown oxidation smelting process,PLC and the typical structure of the industrial control computer are adopted and the real-time detection and display monitor of furnace composition,temperature,air flow,pipeline gas flow,oxygen concentration are realized.The into the oxygen and air drum intake are adjusted according to oxygen concentration in order to ensure oxygen concentration stability in the technical requirements of the range.
