基于PLC的抽锭式电渣连铸自动控制系统设计

Design of Automatic Control System of Pullsout the Spindle Continuous Electric Slag Remelt based on PLC

介绍了用于抽锭式电渣连铸设备中的自动控制系统,该系统由PLC进行控制,工控机通过PC/PPI电缆与PLC通讯,进行熔铸参数的设置。通过传感器对熔铸状态进行采样、监控,实现熔铸过程的自动、平稳进行,并可对铸锭质量进行过程监控。通过实际应用,该系统运行稳定可靠。

In this paper,a automatic control system for pullsout the spindle continuous ESR was introduced.The automatic control system was controlled by Simens PLC.Industurial computer can communicate with PLC via PC/PPI cable,and was used for configuration of remelt parameters.Through the sensors sampling and monitoring of remelt status,casting process can be controlled automically and smoothly,and ingot quality can be monitored also.The practical application shows that the system is stable and reliable.
