Φ12mm热轧带肋钢筋四线切分轧制工艺存在问题及解决措施

PROBLEMS IN FOUR-LINE SPLITTING ROLLING PROCESS FOR Φ 12 mm HOT-ROLLED RIBBED REINFORCED BAR AND THE SOLVING MEASURES

针对Φ12 mm热轧带肋钢筋四线切分生产工艺中精轧机组导板粘钢、切分架次出口堆钢、成品架次出口堆钢、轧槽磨损严重等问题,通过改进轧辊材质、控制轧辊轴向串动及弹跳等措施,实现了Φ12mm热轧带肋钢筋四线切分轧制的稳产、高产。

With measures of improving material quality of rolls and controlling axial motion and bounce,the following problems are solved in four-line splitting rolling process for 12 mm hot-rolled ribbed reinforced bar： steel adhered by guide in finishing mill set,steel piled at exit of splitting stand and end product stand,serious wore in grooves.
