摘要
冶金行业轧钢加热炉步进梁的特点是单体设备自重大、惯性大,要求控制可靠、精度高,运行平稳,同时必须保证工艺要求的步进周期,以满足轧机轧制节奏的需求。以西门子S7-400系列的PLC为控制器,开发的加热炉步进梁控制程序,通过工程项目实际工况调试,实现液压驱动近千吨步进梁的控制要求。
The characteristic of walking beam of steel rolling furnace that single equipment is itself heavy,large inertia. It requires reliable control,high accuracy,smooth operation,and must ensure that the technical requirements of step cycle and requirement of rolling rhythm. With Siemens S7-400 series PLC as the controller,the development of the walking beam control program,Through the commissioning of the actual working conditions of the project,the control requirements of the hydraulic drive nearly a thousand tons of walking beam are realized.
