Wire surface processing for hot dip galvanizing wire production

After annealing, the oxide material on the surface of the wire will be washed by pure water. Then, the acid (HCl) will be adopted to clean oxide material again, later, washed with hot water to clean rudimental acid from wire surface, acid tank adopts complete seal by waterfall. Inlet and outlet of the wire rod parts adopts waterfall seal. It is good in avoiding acid mist leakage Later, put wire into chemical tank for coating chemicals (Zncl2, Ancl2). Dry wire after being coated with chemicals.

The wire surface processing system removes the unneeded oxide material from the wire and is an important preparation before hot dip galvanization.

Equipment specification

* Smokeless acid washing tank.

Adopt normal temperature acid washing. The inner tank is made in V shape. It is convenient for cleaning waste. The main tank is made by PP plate with thickness 20mm . assistant tank is made by enhanced PP material. All the acid tank is block out. There is acid smoke leakage. There are water fall sealing and rubber sealing in the two sides. The effective length of the tank is 12 meters.

* Cold water washing tank

After leaving the acid washing tank. The wires will be going into two section water washing areas. The first section is a recycled system driven by pump. There are double water fall and washing disc. In the inlet area. The water is pumped from bottom to the upper disc. The second section is clean water spray washing. It makes wire completely clean.

* Assistant plating tank (chemical tank)

The tank is made by stainless steel. It is equipped with cover.

Storage trough is heated by electrical, power is 55kw. The storage trough is insulated by insulation material. The temperature is digital display.

* Dryer

It is dried by electrical. Power is 60kw. Drying length is more than 6 meters. The heating temperature is more than 120 degree centigrade. Temperature digital display.

* Control system

* Computer system
