Five, the technological process

1, technology overview

Mr Jimmy, galvanized process throughout the world have occupied in strip continuous hot galvanizing line

The main position, and constantly improve and develop. The main characteristic of this method is to put the preheating furnace and reduction furnace

The annealing furnace and cooling section, through the seal of furnace throat connection for an organic whole, through the net

Natural gas as fuel, with no oxidation heating technology, realization of strip steel continuous annealing, with high quality,

High yield, low consumption, security, and many other advantages, this technique is based on the designed method.

2, the main body equipment according to the technological process arrangement is as follows:

# 1, 2, feeding the small car to # 1, 2, uncoiler, open-book dao 1, 2 - open book clip send 1, 2 - hydraulic transverse cutting and welding platform - tensioning machine 1 - the entry loop - tensioning machine 2 - (CPC) - beating in double roller to roll to annealing furnace, the furnace nose - zinc pot - sink roll to roll stability, air knife - cooling fan and cooling tower to roll - quenching tank to drain roller, double rollers on the (CPC) - tensioning machine 3 - machine to dip coating passivation, hot air drying - export loop - tensioning machine 4 - hydraulic transverse shear - winding pinch (guide) - winding machine (EPC) - unloading car

Through the electronic control system, hydraulic system, pneumatic system and ancillary equipment to realize continuous running.
