摘要
针对传统二次冷却控制不当出现的铸坯缺陷,对弧形连铸机二冷水系统的设计进行改造。在原有的控制系统基础上,通过配置现场检测和调节设备,实时采集现场信号送至PLC。同时增加PLC内部的PID功能模块,以水管的实际流量作为反馈量,完善PLC程序,使系统由原来较为简单的开环控制系统升级为闭环控制系统,以实现对水量的精确控制,获得铸坯最佳冷却效果,满足生产工艺需要,降低漏钢率,提高铸坯外形质量。
Aiming at caster two cold water the slab＇s defect system design and system, through on-site testing and in the traditional two cold water control, the arc continuous transformation are put forward. regulating equipment, the real-time Based on the original control acquisition field signal is sent to the PLC. While increasing the PLC internal PID function module to actual flow pipe as feedback quantity, improve PLC program, made the system more simple open loop control system upgrade for closed loop control system, in order to realize the precise control for water, for casting the best cooling effect, meet the needs of the production process, reduce the leakage rate of steel, improve the quality of the casting shape.
