变频器在固化炉带钢传动的张力控制的应用

Application of Tension Control for Drive System on Solidified Stove of Strip Steel

本文阐述了变频器在固化炉的温度控制和带钢传动控制。其中,传统的矢量控制变频器在开环应用时的动态转速误差约为0.8%,闭环应用时约为0.3%,而ACS800变频器在开环应用时可使动态转速误差减少到0.3%,闭环应用时达到0.1%。

This paper describes the temperature control and drive control of strip steel at solidifying stove to transducer. The dynamic error of rotate speed of traditional vector control of transducer is about 0.8% in the open applications, and is about 0.3% in the closed applications. However, the dynamic error of ACS800 transducer in the open applications can be decreased to 0.3%, and 0.1% in the closed applications.
