艾默生MP420A4R直流驱动装置在舞钢板坯连铸机结晶器振动控制系统中的应用

Application of Emerson MP420A4R DC Drive in Mould Vibration Control System for Wugang Slab Continuous Caster

舞钢1 900 mm板坯连铸机的结晶器振动直流驱动装置老化,备件停产,维修费用高且修复后运行不稳定。基于这种现状并结合实际生产需要,在不改变西门子PLC程序控制的前提下,采用艾默生MP420A4R直流驱动装置,对结晶器振动直流装置进行升级改造,取得了良好的效果。

The mould vibration DC drive of Wugang 1 900 mm slab continuous caster is degraded,the spare part is no more available,the maintenance cost rises and the operation of the repaired device is neither stable nor reliable.Based on such conditions and actual production demand,Wugang upgrades and revamps the existing mould vibration DC drive by using Emerson MP420A4 R DC drive without modifying Siemens PLC program control,which receives good results.
