活套装置在带钢热连轧控制系统中的地位举足轻重,活套编码器的安装防护、编码器稳定应用是制约精轧区域设备稳定性的难点和瓶颈问题。本文着眼于生产实践,采用冗余优化,自行设计实施活套编码器可调式的安装结构;开发出活套编码器的冗余自动切换和故障报警功能,文章对于冶金带钢轧制活套装置系统的设计应用有很大的参考价值。 The position of the looper in the hot strip rolling control system plays an important role. The installation and protection of the looper encoder and the stable application of the encoder are the difficulties and bottlenecks that restrict the stability of the equipment in the finish rolling zone. This paper focuses on production practice, the use of redundant optimization, design and implementation of self-adjustable encoder adjustable mounting structure; developed a flexible encoder automatic redundancy switching and fault alarm function, the article for the rolling mill lamellar metallurgical device System design and application of great reference value.
