摘　　要：为实现传统铜管坯水平连铸水冷控制系统在线自动化精准控制,提高生产质量与精度,改善管坯组织性能,对现有铜管坯水平连铸一冷水控制进行分析。采用程序设计和物理实验验证的方法,开展了基于可编程逻辑控制器(PLC)闭环策略下石墨结晶器冷却水量自动控制的相关研究。实验结果表明,基于闭环控制逻辑的自动水冷控制系统可以将流量波动控制在±0.5 L/min范围内,离散系数为2.68×10^(-3),明显小于传统水冷控制系统,铜管坯水平连铸一次冷却水闭环控制系统可以实现连铸过程的精确控制。In order to achieve online automation and precise control of water cooling system of horizontal continuous casting of the traditional copper tube billets,improve production quality and accuracy,and improve the structural properties of the tube billets,an analysis is conducted on the existing copper tube billets horizontal continuous casting and water cooling control.Program design and physical experimental verification are adopted to carry out correlational research on the automatic control of cooling water volume of crystallizer based on a closed-loop strategy of PLC controller.The experimental results show that automatic water cooling control system based on closed-loop control logic can control flow fluctuation within the range of±0.5 L/min,with a discrete coefficient of 2.68×10^(-3),which is significantly smaller than traditional water cooling control system.Closed-loop control system for primary cooling water system for horizontal continuous casting of copper tube billets can achieve precise control of the continuous casting process.
