一、PC鋼絲生產(chǎn)線生產(chǎn)工藝流程
原料進(jìn)場檢驗(yàn)→酸洗除銹磷化→拉拔成型→穩(wěn)定化消除應(yīng)力處理→成品檢驗(yàn)、包裝。
其中：拉拔成型→穩(wěn)定化消除應(yīng)力處理流程包括如下工序:
直線式連續(xù)放線架→第一道拉絲→第二道拉絲→第三道拉絲→第N道拉絲→成型→中頻感應(yīng)加熱及水冷→張力裝置→牽引→剪切→收線。

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
