Purpose:Remove the oxide layer on the surface of the wire rod, chemical reaction;Medium:HCl
Temperature:about 35ºC-60ºC(According to different pickling process)
Time:Total about 30 minutes.
4.2.05:Rinsing-2
Purpose: Clean the wire rod after pickling to remove some residual acid and ferrous iron;
Medium: water from Rinsing-3
Temperature: Hot
Time: 0.5~1 minutes.
4.2.06:Rinsing-3&4
Purpose: Further cleaning the wire rod surface;
Medium: water from High pressure spraying-1;
Temperature: normal
Time: 0.5~1 minutes.
4.2.06:High pressure spraying-1
