Advantages of Cathode Refurbishment
- Improvement in production of Copper cathode
- Reduction in cost of production
- Better shapes of cathode for better presentation
- Improved operation in EW
- Enhanced electro conductivity
- Increase in production efficiency
- Reduction in maintenance cost
- Improvement in copper quality
Why Cathode Refurbishment is Required?
- Due to repeated operation, the surface of the Cathode plate (made of Stainless Steel) and Copper hanger bar gets deteriorated. Also the cathode plates get bent during the process. So refurbishment of the cathode plate is required to get better copper deposition on the plate during EW process.
-
Following are some of the reasons why Cathode plates get deteriorated during the EW process :
I. The cathodes bend after grading because of its shape and size
II. Physical erosion caused by the two knives of the stripping machine
III. Crane operators are also a cause of bending if they don’t handle the cathode gently
IV. Pressure from the two cylindrical structures used to unclog the copper that is stucked in the plate
-
Without refurbishment, following problems occur during EW process with repeated use of Cathode plates:
I. Poor electrical conductivity
II. Poor quality of copper as final product
III. Too much copper plugin in the plates leading to wastage
IV. Scratching of the plates resulting in short life of the plates - With Cathode refurbishment, Current efficiency/electrical conductivity during EW Process improves.
- Plastic Edge Strips get broken during EW process, which also gets replaced during cathode plate refurbishment.
- The quality of Cathode plate, Anode plate and edge strips impact the productivity of the process. With cathode refurbishment, there is guaranteed increase in productivity.
- Smooth and shiny surface of the cathode plate ensures better presentation.
