铸轧冷却水温度PID控制功能的取代

Casting and Rolling Cooling Water Temperature PID Control Function Substituent

铸轧生产过程中，轧辊冷却水温度的稳定，是影响铸轧卷板型质量的重要因素之一。本文介绍了一种控制模型，用PLC编程方法替代PLC中调用PID模块。实际应用中提高了温度控制精度，同时具有通用性。

The equability of cooling water temperature is the important option affecting caster quality in aluminium caster process. Design one control model. Use PLC ladder program to instead of usually calling PID model. Improve control precision in fact at the same time it has currency.
