摘要
针对连续退火炉原有燃烧控制系统目前存在的问题,对辐射管加热段进行优化.利用横河的DCS集散控制系统,分析空气和煤气的配比,及其他影响因素,建立控制参量之间的关系,推出退火炉燃烧系统的传递函数.并运用时序脉冲燃烧控制的方法对辐射管加热段进行优化控制,提高了控制精度,减少了带钢表面氧化,同时提高加热效率,节能环保效果显著.
In view of the existing problems in the original combustion control system of continuous annealing furnace,the heating section of radiant tube was optimized.Based on DCS distributed control system of YOKOGAWA,the proportion of air and COG and other influencing factors were analyzed,and the ralationship among these control parameters was established,so then the transfer function of annealing furnace combustion system was successfully enduced.By using the method of timing pulse combustion control to optimize the heating section of radiant tube,which was proved to have a remarkable effect on energy conservation and environmental protection,the control accuracy was optimized,and the surface oxidation of strip steel was reduced,and the heating efficiency was improved at the same time.
