仪控部分主要实时显示与烧结工艺有关仪倥信号(如压力、流量、温度 等),并且通过画面操作对点火温度、风箱负压进行控制。 • 点火温度控制:点火温度控制是通过控制煤气和空气的流量来实现的。采 用串级双交叉控制和非串级双交叉控制的控制方法。串级双交叉控制是一 种非常先进的控制方法,是以维持合适的空气,煤气比值为手段,达到燃 烧时始终维持低过剩空气系数,从而保证了较高的热效率,同时减少了排 烟对环境的污染。串级双交叉控制以点火温度调节为主回路,以煤气流量 和空气流量为副回路的串级调节回路。串级双交叉控制分为自动控制和手 动控制;非串级双交叉控制分为PID手动、PID自动和远程手动控制。高炉系统是炼铁系统中的一个重要组成部分。高炉的功能就是利用铁矿石、焦 煤、助熔剂等原料产生出铁水。原材料从高炉顶部注入,热风从高炉底部吹 入,经过一段时间的冶炼,后铁水从炉底排出进入下一道工序,而沉淀在炉 底的铁渣通过冲渣系统排出。它的主要工艺线可以分为热风炉系统、高炉炉顶 系统、高炉矿槽系统、高炉本体系统和水处理以及除尘控制系统等。
