摘要

连续退火炉的工艺过程就是钢材料的热处理的过程,在热处理之后,钢材的柔韧性和
强度都会有很大的提高,然而老式退火炉能耗高,控制精度低,因此,我们在老式退火炉
控制系统的基础上,进行改进,调整了控制方法,并且提出了新的控制理论。经过实践证
明,该自控系统设计合理,运行可靠,达到绿色环保要求,降低了能源的消耗,同时温度
控制精度较高,退火质量也大大提高了。最后,我们通过仿真软件 MATLAB 在实验室进
行仿真,使得模糊 PID 控制理论更加成熟。更好的运用于实际。
本文介绍了连续退火炉的发展现况、工艺概述、流程、操作方式和设备的连锁条件,
阐述了本文所做的三方面工作:首先消化了老式退火炉温控制系统,生产工艺、操作温度、
控制方式,提出了新的控制方法,并在实验室进行了仿真,为实践奠定了理论基础,其次,
设计了基于模糊控制的炉温模型,得到影响系统的主要参量,运用仿真软件验证它的精确
性。最后设计了一种基于模糊 PID 控制温度控制系统,对传统 PID 控制添加了模糊控制的
理论,设计了模糊 PID 控制系统的结构和算法。

Abstract
Continuous annealing furnace process is the process of heat treatment of steel, after heat
treatment, flexibility and strength of steel will have greatly improved, but the old furnace
consumed high energy and control accuracy is low, therefore, we based on old furnace control
system, improved and adjusted the control method, and proposed a new control theory. Practice
has proved that the automatic control system design is reasonable and reliable, meetinng
environmental protection requirements, reducing energy consumption and high precision
temperature control, annealing greatly improved quality a lot. Finally, we simulate it with matlab
software in the laboratory, so the fuzzy PID control theory is more mature and practical.
This article describes the current development,process overview,operation mode and
equipment chain of continuous annealing furnace,this paper describes the work done in three
areas: firstly, to digest the old furnace temperature control system, production process, operating
temperature control mode,then we propose new control method,simulate in the lab and laid the
theoretical foundation into the practice, secondly, based on fuzzy control,we design the
temperature model to get the main parameters affecting the system and use simulation software
to verify it
