通过对武钢高线轧机第7架出口扭转导卫损伤特点和原因进行深入分析,提出减少堆钢和提高使用周期的具体改进措施,据此将第7架分体导卫改为扭转组辊式整体导卫并应用于现场生产,成功解决了其频繁堆钢和使用周期短的问题,不但提高了高线轧机作业率,同时还节约了生产成本。 Based on the analysis of the characteristics and causes of torsionally guiding damage at the exit of the 7th high-speed rolling mill of Wuhan Iron and Steel (Group) Co., Ltd., the paper put forward the specific measures to reduce the stacking steel and improve the service life. Based on this, As a whole, it is applied to on-site production and successfully solved the problem of frequent pile-up and short service life, which not only improves the operation rate of the high-speed rolling mill but also saves the production cost.
