摘要
二级系统是实现连续退火炉智能化控制的关键,本文研究了该系统的主要功能,包括实现同退火炉PLC和主线PLC之间的数据通讯,根据带钢规格和实时炉况进行温度控制模型计算和炉辊凸度模型计算,使带钢温度接近目标温度,并用于分析和预防带钢的跑偏和瓢曲,提高带钢在炉内运行的稳定性。通过运用minitab软件进行二级模型控制和一级控制的加热段温度稳定性比较,实验表明二级控制效果要优于一级控制,极大地减少了人员的手动操作,提高了炉内温度控制的智能化水平。
The level 2 system is the key to realize the intelligent control of continuous annealing furnace. This paper studies the main functions of the system, including realizing the data communication with annealing furnace PLC and main line PLC, calculating the temperature control model and furnace roll crown model according to the strip steel specification and real-time furnace condition, so as to make the strip steel temperature close to the target temperature, analyze and prevent the deviation and bending of strip steel, and improve the stability of strip steel operation in the furnace. By using Minitab software to compare the temperature stability of the heating section between the level 2 model control and the level 1 control, the experiment shows that the effect of the level 2 control is better than the level 1 control, which greatly reduces the manual operation of personnel and improves the intelligent level of temperature control in the furnace.
