 The Technological process and equipment function describe the main equipment, which is arranged as follows according to the technological process:

 Configuration equipment at the entrance section:

1, 2# coil loading cart→ 1, 2# pay-off reel → 1, 2# scraper of pay-off reel → pinch roll after pay-off reel → five-roller pinch straightening machine → hydraulic cross-cutting shear → welding platform → 1# tension bridle roll → entry loop (three automatic aligning machines) → 2# tension bridle roll → 1# double roller aligning machine(CPC) → tension measuring machine → annealing furnace → furnace nose → zinc pot → sink roll → air knife → air cooling device→ high tower aligning machine → high tower steering roll → quench tank → squeezing roll → 2# double-roll aligning machine (CPC) → 3# tension bridle roll → tension leveler → 4#tension bridle roll → dip coating Passivation → drying device after Passivation→ exit loop ( 1 Automatic Aligning Machine) → 5# tension bridle roll → 

hydraulic cross-cutting shear →pinch roll after coiler (guide plate) →coiler (EPC) → unloading cart

Continuous Operation is Achieved through the Electrical Control System, Hydraulic System, Pneumatic System and Auxiliary Equipment.
