Cause Analysis and Treatment of Abnormal Shear in Head Cutting Flying Shear of Hot Rolling

Xiaoyan Chen

Abstract

Precise shearing of flying shear plays a very important role in cost control of a hot-roll line. The malfunction of sensors which help to locate where to cut accurately makes it difficult to achieve this goal. This paper discussed in detail three key control processes in completing precise shearing. Possible causes of abnormal shear in production practice were analyzed, based on which the optimal signal switching control measures was put forwards. A monitoring system watchdoged the signals from sensor. If sampling showed that malfunction happened, a backup signal was used. Also the possible backup signals were discussed how to replace the breakdown devices. In practice, these measures obtain a good application effect in precise shearing. Mistakes in cutting are reduced to minimum.
