针对高碳钢盘条加工的预应力混凝土钢丝在轨枕模型中张拉断裂问题,对张拉断裂、拉拔断裂及盘条试样进行检验分析,并结合工艺参数控制情况,分析断裂产生的原因,提出改进的措施。经生产应用,后续生产盘条加工的钢丝未出现张拉断裂现象。
Aiming at the problem of tension and fracture of prestressed concrete steel wire with high carbon steel wire rod in sleeper model, the tensile and tensile fracture and wire rod sample are tested and analyzed. The reason of fracture is analyzed with the control of process parameters , Proposed measures for improvement. After production and application, follow-up production of wire rod processing does not appear tension fracture phenomenon.
