The main equipment is arranged according to the process as follows:
1. 2# feeding trolley →1. 2# Uncoiler → uncoiler 1, 2 → uncoiling clamping 1, 2 → hydraulic cross-cutting shear → welding platform → tensioner 1 → inlet loop → tensioner 2→ double roller centering (CPC) → runout roller → annealing furnace → furnace nose → zinc pot → sinking roller → air knife → cooling fan → cooling tower steering roller →quenching tank → extrusion roller → double roller centering (CPC) → tensioner 3→ tensioning machine → dipping and passivation → hot air drying → outlet loop → tensioner 4 → hydraulic cross-cutting shear → winding and clamping (guide) → winder (EPC) → discharge trolley a
