2. Description of process and equipment function The main equipment is arranged according to the process as follows:
Entrance section configuration equipment:
1. 2# loading trolley → 1, 2# uncoiler→ 1, 2# uncoiler→ uncoiling and clamping machine→ five-roller clamping and straightening machine→ hydraulic cross-cutting shear→ welding platform→ 1# tensioning machine→ inlet loop (automatic centering three sets), → 2# tensioning machine→ 1# double roller centering (CPC) →runout roller→annealing furnace→ furnace nose→ zinc pot→ sinking roller→ air knife→cooling→ high tower centering machine→ high-tower steering roller→quenching tank→ extrusion roller→ 2# double roller centering (CPC)→ 3# tensioning machine→ tensioning machine→4 #张紧机→ Dipping Passivation → Passivation Drying → Outlet Loop (Automatic Centering Set) → 5# Tensioning Machine→ Hydraulic Cross-Cutting Shear→ Rewinding and Clamping Machine (Guide Plate) → Rewinder (EPC) → Discharging Trolley
Continuous operation is achieved through electronic control system, hydraulic system, pneumatic system and auxiliary equipment.
