Lead Anodes Electrowinning

• Anode plate for copper electrowinning industry is cold rolled lead alloy anode sheet with uniform grain structure, high corrosion resistance etc.
• This anode plate(lead alloy anode sheet)connects with the Copper hanger bar double-side welding with Lead alloy coating, or plate plug-in welding.
• The copper bar is coated with tin and then lead coated.
• The good welding technique and good quality anode plate and hanger bar allows the anode plate could use in harsh environment for long time.

Cold rolling of anodes subsequent to casting improves the efficiency and life of the anode by separating the grain structure and stretching and orientating the grains for a more homogenous microstructure. This improves the anodes performance through:

Uniform conditioning and corrosion resistant

Opposition against creep

Further developed conductivity

Reduced porosity
