摘    要：首钢迁安钢铁有限责任公司2250热轧厂热连轧生产线2台卷取机的传动系统采用德国Siemens公司全套带单独励磁的交直交变频器。在卷筒主传动变频控制器中采用了T400工艺板,实现了转子初始定位控制、带钢卷取的张力控制和速度控制等功能。文章介绍了传动系统的组成及特点、传动矢量控制原理、卷取张力控制等。运行结果表明,交直交变频器的控制及卷取控制的性能指标和动态性能良好。

Abstract: The drive systems of two coilers of the 2 250 mm hot strip mill at Shougang Qianan Iron & Steel Co.,Ltd.adopt Siemens AC-DC-AC converter products with separated excitation.For the mandrel drive control,Siemens T400 boards are applied in this application to implement initial positioning,tension control and speed control functions.In this paper,the configuration of the drive systems is introduced first,and then the feature of the systems as well as the principle and realization of the vector control and the tension control are explained.Operational data from the rolling site show that the performance of the drive control systems is satisfactory.
