薄带铸轧生产线设备紧凑,生产工艺更加低耗高效,是钢铁工业流行发展的趋势.SINAMICS S120控制系统应用在薄带铸轧主轧机传动系统上,可以根据需求灵活增添功能配置.通过介绍该生产线工艺流程,突出S120传动控制系统的优势.此外,针对S120控制系统设计和应用,尤其是负荷平衡控制、SINAMICS Link通讯、安全转矩关断等特殊应用的实现进行了详细的阐述.

SINAMICS SL150是西门子公司新型全数字矢量交交变频控制系统,用于替换上一代产品SIMADYND系统.在SL150系统中,针对冶金轧制有一些特殊的应用,包括负荷平衡、负荷观测、陷波滤波器等,其中负荷平衡保证了上下辊输出转矩的平均分配,采用负荷观测器的控制系统具有较强的抗负荷扰动性,明显减少轧机动态速降和恢复时间,陷波滤波器的运用消除了机电共振现象,这些应用对生产线的正常快速生产、保证产品质量发挥着重要作用.

Seamless pipe is an important economic steel. The application of retained mandrel pipe mill,overcomes the limitation of weight and length,improve the quality of pipe,and make the diameter and length increasedeffectively. By the description of retained mandrel system equipment structure,and the rolling process,introduced theapplication and characteristic. And described the design and application of the electric drive control system,especiallythe configuration and solution of control task by the typical 1 master-3 slave control systems base on S120 inverter indetail.

According to the work characteristics and process requirements of hole rolling production line,the control accuracy and response speed of manipulator are related to the quality of production product,so the manipulator control is very important.Taking actual application into account,the speed closed-loop control position PID regulator were applied to realize synchronization of manipulator in front of the machine and rollaway beds behind the machine.Straightening manipulator and delivering steel normally were realized by torque control.Field applications indicate that the system performance of manipulator is good,and the program is entirely feasible.
