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.
Medium: tap water
Temperature: 85-95ºC
Time: 2-3 min minutes.
 

4.2.13:  Saponification


Purpose: To saponify the surface of the wire rod;
Medium: soap
Temperature: ≤80ºC
Time: 1-2min minutes.
