Abstract

The paper is devoted to the development and commercial application of the method of pressure control in a continuous heating furnace that takes into account the compensating influence of metal discharge dampers. Based on the actual technological data, we deduce a differential equation (in the form of an aperiodic link of the first order), which describes the influence of metal discharge dampers on the pressure drop inside the furnace. On the basis of this equation, we develop a method for the predictive control, which enables us to compensate the influence of discharge dampers. The method was checked in a metal-heating furnace No. 2 of the Rolling Shop No.1 at the A. A. Ugarov OEMK JSC and by analyzing the results of experiments aimed at comparing different methods of compensation of pressure drops. The developed method makes it possible to reduce the pressure drop (by 5%), significantly decrease the time of compensation of perturbations caused by the action of dampers (by more than 200%), and improve the stability of operation of temperature zones in the region of discharge.

加热炉空间的压力控制要考虑到金属放电阻尼器的工作

本文研究了考虑金属放电阻尼器补偿影响的连续加热炉压力控制方法的研制和工业应用。根据实际工艺数据，推导了一个微分方程（以一阶非周期环节的形式），描述了金属放电阻尼器对炉内压降的影响。在此方程的基础上，我们提出了一种预测控制方法，使我们能够补偿放电阻尼器的影响。在a . a . Ugarov OEMK JSC 1轧钢车间2号金属加热炉上对该方法进行了验证，并对不同压降补偿方法的实验结果进行了分析比较。所开发的方法可以降低压降（5%），显著减少阻尼器作用引起的扰动补偿时间（200%以上），提高放电区域温区运行的稳定性。
