PLC定尺系统在炼钢厂5^#连铸生产中的研究与应用

Researches and Application of PLC Cut-to-length System in No.5 Continuous Caster Production

为解决炼钢厂5^#连铸机的红外无接触定尺系统受火焰切割干扰较大，切割精度不高，经常造成铸坯长短尺的问题，开发了PLC定尺系统，很好地解决了定尺问题。介绍了PLC定尺系统的原理以及使用效果。

To solve the problem of often causing falling short for casting blanks for the No. 5 continuous caster at the Steelworks by heavier interference of flame cutting to infrared non-contact cut-to-length system and not high enough cutting precision, the PLC cut-to-length system was developed, satisfactorily solving the cut-to-length problem. The principle of the system and its usage results are presented,
