摘要
介绍连轧棒材两线、三线、多线(四线、五线)切分孔型特点,同时针对三线切分一道预切分孔型系统存在的问题,优化孔型,重新设计双道预切分孔型系统,在孔型系统共用基础上,唐钢一棒生产线Ф16螺三线切分生产成功,解决了三线切分生产过程切分不均,稳定性差问题,大大提高Ф16螺生产水平。
News briefing the feature of slitting pass of continuing bar rolling of two thread, three thread and poly-thread （four and five thread）and aim at the question of three thread pre-cut slitting pass system, optimize and redesign the pre-cut slitting pass system, successfully on line of 16screw three thread bar.
