一、PC钢丝生产线生产工艺流程
原料进场检验→酸洗除锈磷化→拉拔成型→稳定化消除应力处理→成品检验、包装。
其中:拉拔成型→稳定化消除应力处理流程包括如下工序:
直线式连续放线架→道拉丝→第二道拉丝→第三道拉丝→第N道拉丝→成型→中频感应加热及水冷→张力装置→牵引→剪切→收线。

Raw Material Inspection→ Picking and Phosphating→ Drawing & Molding→ Stabilizing& Stress Removal.
Treatment→ Finished Product Inspection & Packing
From Drawing to Stabilizing & Stress Removal, the detailed technical process follows as below:
Payoff Continuously in Straight Line→ First Drawing→ Second Drawing→ Third Drawing→ Fourth Drawing→Molding→ IF Induction Heating & Water Cooling→ Tension Machine→ Traction→ Shearing→Take-up
