Production process flow of PC steel wire production line
Raw material entry inspection → acid pickling, rust removal, and phosphating → drawing and forming → stabilization and stress relief treatment → finished product inspection and packaging.
The process of drawing and forming → stabilizing and stress relief includes the following steps:
Linear continuous wire laying frame → First wire drawing → Second wire drawing → Third wire drawing → Nth wire drawing → Forming → Medium frequency induction heating and water cooling → Tension device → Traction → Cutting → Wire collection.
