四线切分轧制常见工艺问题及解决措施

Often Occurred Failures during Bar Four-strands Splitting Rolling and Its Countermeasures

针对Φ12mm热轧带肋钢筋四线切分生产工艺开发以来遇到的切分道次顶出口、成品道次顶出口、各线轧件尺寸不一致的问题,分析了其形成原因,提出了改进轧辊材质、提高轧辊加工精度、提高导卫安装精度等技术措施,实现了四线切分轧制的稳产、高产。

There were some failures duringΦ12mm ribbed bar four-strands splitting rolling,such as the guide and guard units of splitting and finishing pass damaged by piece,the piece size difference of four strands. Therefore,the causes were analyzed,and the countermeasures were put forward,including improvement roll material and working precision,assurance the installation precision,etc.At last,the stability production and high productivity were realized.
