摘　　要：介绍了由全氢罩式炉机组组成的全氢罩式退火炉控制系统。讨论了应用西门子公司的S7-300系列PLC和WINCC图形软件如何实现在退火过程中对设备的自动控制和实时监控功能。为了提高退火质量和控制精度,在温度控制问题上采用PID控制算法结合脉冲循环燃烧算法。脉冲循环控制算法在提高被控温度的均匀性和延长烧嘴的寿命上有很好的效果。运行结果表明,该控制系统性能优越,效果良好。An annealing furnace control system which consists of the hydrogen bell type furnace unit is introduced in this paper. The realization of the annealing process automatic controlling and real - time monitoring with Siemens S7 - 300 series PLC and WINCC graphics software is also included. In order to improve the quality of annealing and precision level, PID control algorithm combining with pulse cycle burning algorithm are used to work out the temperature control issue. It is effective to improve the evenness of temperature and extending the life of the burner with pulse cycle burning algorithm. The operation results show that the control system performs well.
