Pickling and phosphating (boronizing) production line

Short Description:

Fasten Hopesun pickling and phosphating (boronizing) production line mainly used for pickling and phosphating treatment to remove the oxide film on the surface of wire rod. After pickling, the surface of wire rod is clean and bright, qualified enough for further deep processing. Then, phosphating to form a phosphate film on the surface of the wire rod, or boronizing to formed a loose and porous puffed coating on wire rod surface convenient for wire drawing.

Parameters

1	Pay-off: load the wire rod on the production line.
2	Water seal & Degreasing: Degreasing and cleaning the wire rods entering the production line to wash away the oily attachments on the surface.
3	Water seal & Degreasing: Degreasing and cleaning the wire rods entering the production line to wash away the oily attachments on the surface.
4	Rinsing: Clean the wire rod after degreasing to remove oils.
5	Pickling: Remove the oxide layer on the surface of the wire rod, chemical reaction.
6	Rinsing: Clean the wire rod after pickling to remove some residual acid and ferrous iron.
7	Rinsing: Further cleaning the wire rod surface.
8	High pressure spraying: 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.
9	Surface conditioning: 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.
10	Phosphating: Form a phosphate film on the surface of the wire rod.
11	High pressure spraying: Remove the phosphating liquid and slag on the wire rod after phosphating.
12	Rinsing: Remove the phosphating liquid and slag on the surface of the wire rod after spraying.
13	Boronizing: 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.
14	Liming: Neutralize the residual acid on the surface of the wire rod. Formed a liming coating on wire rod surface convenient for wire drawing.
15	Saponification: Saponify the surface of the wire rod.
16	Drying: Dry the surface of the wire rod.
17	Take-up: Unload the processed wire rods from the production line.
