Single wire heavy electro galvanizing line for steel wire
For soft black annealing wire to make barbed wire and chain link mesh
1.1 The production process
Coil stand pay-off→ Tension →Electrolytic acid pickling (1000A)→water washing→Water washing →heavy zinc coating(8000A) →Water washing → Nitic acid →Water washing →Passivation →Water washing→Hot water washing →Baking→ D550 horizontal coil take-up .
1.2 Chief parameter of galvanizing line
Diameter of treated wire: | ф1.0-ф4.0mm carbon steel wire; |
Thickness of zinc coating: | 40-300g/m2; |
Production speed: | Max.100m/min ,speed can be adjusted by frequency conversion motor. |
Total power consumption | 90KW. |
Total length of whole machine: | 40 meters |
1.3 Brief introduction of galvanizing line
1. Pay-off: Coil stand pay-off
2. Electrolytic acid pickling part: Complete close electrolytic acid pickling, barrel is made of 316 stainless steel, magnetic pump is used for acid washing and circulation, 1000A/12V rectifier, copper bars distribute according to the size of rectifier, the bottom tank of acid pickling is movable and easy for clean.
3. Heavy zinc coating: Complete close design, 316 stainless steel made barrel, 8000A/12V rectifier, copper bars distribute according to the size of rectifier, anode is made of 5*50mm Ti plate, magnetic pump is used for circulation, the effective length of zinc coating is 250m.
4.Passivation is re-winding type, so the tank will be only 5m length, but the real passivation is about 42m.
5. Baking: Short circuit type baking, voltage regulator for temperature adjusting, consume low electricity, fast temperature rise and safety.
6. Horizontal D550 take up.
