摘要： 为了提高连续退火模拟实验机的温度控制精度,基于传热学理论和快速自适应的控制思想,构建了连续退火模拟实验机过程控制的数学模型.该模型根据实验过程中采集的数据,实时修正退火过程的相关参数,在加热阶段和冷却阶段分别对加热电流和冷却气体流量等工艺参数进行调整和动态补偿,从而确保了退火过程温度的控制精度.实际应用结果表明,该数学模型温度控制精度达到±10℃,满足退火实验机温度过程控制要求.

Abstract: To improve the temperature control accuracy of a continuous annealing simulator, a mathematical model was developed for the process control of the simulator on the basis of the theories of heat transfer and adaptive control. According to the data acquired in experiments, the relevant annealing parameters were modified in real time, and such parameters as heating current and cooling gas flowrate were readjusted and compensated dynamically in either heating or cooling process, thus ensuring the accuracy of temperature control. In application the model showed that the temperature control accuracy is ±10°C, i.e., available to meet the requirements for process control of the annealing simulator.
