The company intends to adopt the ring production line, and the annular production line has the advantages of high automation and high production efficiency.
Process flow: pendant to acid pickling, water washing, auxiliary plating, drying, zinc immersion, water cooling, passivation, unloading, inspection and dressing.
The main features of the production line are:
1. Rapid rust removal of steel components;
2, the iron ion content of the plating aid is less than 1g/L.
3. Hot dip plating at low temperature and constant temperature;
4, low chromium emission passivation;
5. Saving zinc consumption technology is 5 to 10% lower than that of general structural parts, and 3% of acid washing fluid is saved.
