4.2.01:Loading
Purpose:Send the steel wire rod to the production line;
Time:About 3 minutes.
4.2.02:Water seal & Degreasing
Purpose: Degreasing and cleaning the wire rods entering the production line to wash away the oily attachments on the surface;
Medium:Degreasing liquid;
Temp.:about 60-80ºC(KMnO4 90-95ºC)
Time:About 3 minutes.
4.2.03:Rinsing-1
Purpose: Clean the wire rod after degreasing to remove some oils etc.
Medium: water from Rinsing-2
Temperature: Hot water
4.2.04:Pickling-1~4
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
Purpose: To perform high-pressure washing on the inner and outer surfaces of the wire rod to remove residual acid and ferrous ions on the surface of the wire rod;
Medium: industrial water;
Temperature: normal
Time: 0.5~1 minutes.
4.2.07:Surface conditioning
Purpose: to remove most of the ferrous iron and iron compounds remaining on the surface of the wire rod after pickling;
Facilitate the formation of phosphating film with fine and compact grains;
Improve the adhesion of phosphate coating;
Medium: oxalic acid
Temperature: 30~60ºC
Time: 2~3 minutes.
4.2.08:phosphating 1~2
Purpose: to form a phosphate film on the surface of the wire rod;
Medium: zinc phosphating solution
Temperature: 75-90ºC
Time: about 8 minutes (low carbon);
about 5 minutes (high carbon)
4.2.09:High pressure spraying-2
Purpose: To remove the phosphating liquid and slag on the wire rod after phosphating;
Medium: overflow water from Rinsing-5
Temperature: normal
Time: 0.5~1 minutes.
4.2.10:Rinsing-5
Purpose: To remove the phosphating liquid and slag on the surface of the wire rod after spraying-2;
Medium: tap water
Temperature: normal
Time: 0.5~1 minutes.
4.2.11:Boronizing
Purpose: Neutralize the residual acid on the surface of the wire rod. Formed a loose and porous puffed coating on wire rod surface convenient for wire drawing.
Medium: Borax
Temperature: ≤95ºC
Time: 0.5~1 minutes.
4.2.12:Liming
Purpose: Neutralize the residual acid on the surface of the wire rod. Formed a liming coating on wire rod surface convenient for wire drawing.
