摘要
阐述了连铸生产中存在的问题,设计了变频调速系统以取代直流调速系统。实现了PLC对变频器和两台变频器间的联锁控制,并给出了PLC控制程序框图。实际运行结果表明:本系统安全可靠、故障率低,性能优于原直流系统。
The existing problems in continuous casting production are introduced. A variable frequency speed regulation system is designed to replace DC speed regulation system. The control is realized with PLC between interlock system and two inverters. The flow diagram of PLC is also given. The result shows that this system is safe and reliable,fauh rate is low,performance is better than DC speed regulation system.
