2. Description of process and equipment function
The main equipment is arranged according to the process as follows:
1. 2# loading trolley →L, 2# uncoiler → uncoiler 1, 2→ uncoiling clamping 1, 2→ Hydraulic cross-cutting shear → welding platform → tensioner 1→ Inlet loop (horizontal) → double roller centering (CPC) → tensioner 2→ tensioning roller →annealing furnace→ furnace nose→ zinc pot → sinking roller→ air knife → cooling fan→ cooling tower steering roller→ 90-degree guide system→ quenching tank→ extrusion roller→ double roller centering (CPC) → tensioning machine 3→ tensioning machine→ dipping and passivation →hot air drying→ outlet loop → tensioner 4→ hydraulic cross-cutting shear → winding and clamping (guide) → winding machine (EPC) → unloading trolley
