摘　　要：针对低松弛预应力钢丝稳定化生产线生产螺旋肋钢丝速度较低、故障率高、废丝多的问题，对螺旋器的结构进行了改进，把单级螺旋器改进成双级螺旋器，一级螺旋器的润滑、冷却介质均采用循环的湿式润滑剂。改造后，生产06．0～7．0mm，φ4．8mm螺旋肋钢丝的速度分别由原来的75m／min，120m／min提高到149m／min，219m／min，每年减少由于设备维修等造成的停机时间120h。Aiming at the problem of low speed, high failure rate and much waste wire when helix ribbed wire was produced in low relaxation prestress steel wire stabilization production line, the structure of spiral organ was improved. Single-stage spiral organ was altered into double-stage spiral organ. Lubrication, cooling media of single-stage spiral organ adopted cyclic wet lubricant. After alteration, the speed of producing 06.0 - 7.0 ram, 04.8 mm helix ribbed wire is raised from 75, 120 m/min to 149, 219 m/min respectively. The 120 h downtime is shortened for the aspect of equipment maintenance every year.
