摘　　要：针对φ10mm带肋钢筋五线切分生产中出现的切分刀粘铁、K_1孔顶出口及线差等问题进行了原因分析,提出K_1孔轧辊刻点区分五线的先进操作法,并在孔型、导卫系统、导卫安装、轧辊加工等方面提出了相应的解决措施,实现了φ10mm钢筋五线切分的稳产、高产。Aimed at the problems of iron-sticking on the segmentation knives,rolled piece hitting the exit guide and guard of K_1 pass,and piece size difference among the five-strand,the causes were analyzed.The operation method of engraving a mark on the roll to distinguish the different strand was put forward.Also,other countermeasures were put into practice including rolling pass improvement,guide and guard improvement,and roll turning improvement.And the 5-strand splitting rolling for φ10 mm ribbed bar was carried out more stably and high yield.
