摘　　要：介绍了轧制各种带有旋向要求的螺旋钢筋的技术难点和关键技术,通过在轧机上增设横肋位置对正调节装置和修改孔型系统,莱芜钢铁集团有限公司棒材厂成功生产出左右旋高强度树脂用锚杆钢筋、HRB500及PSB785～PSB1030左右旋精轧钢筋。The technology difficulty and key process of spiral steel bar with turning direction rolling were proposed. The sinistral and dextral high strength resin anchor steel bar of HRB500 and sinistral and dextral finishrolling spiral steel bar of PSB785～PSB1030 were produced successfully by adding transverse rib position adjusting device and revising pass system at bar plant of Laiwu Iron ＆ Steel Group Co. , Ltd.
