基于可编程控制器的冷轧机自动控制系统

冷轧无缝钢管的生产工艺复杂、过程烦琐,具有独特的生产特点,因此冷轧机自动控制系统是一个复杂的系统.整个系统由可编程控制器、全数字式直流调速系统、芯棒断裂检测系统、管料跟踪系统等构成.本文主要分析了系统的原理、组成、功能及自动控制过程.最后提供了几点在生产维护中的经验.

Automatic control system of cool rolling mill based on programming logical controller

In the production of cool rolling seamless steel pipe,its technology is complex,process is tedious and character is special,so the automatic control system of cool rolling mill is a complex system.It includes programming logical controller,digital direct current adjustable rate system,steel wick stick's crackle detect system,steel pipe track system.The paper mainly analyses the compositions,functions and automatic control process of the whole system.It offers some experiences in the uphold of day?to?day work.
