Cathode Bar (Copper Cored/Split)

The Hall-Heroult process, the industrial method for the smelting of primary aluminum, involves passing a large electric current through a molten mixture of cryolite, alumina and aluminum fluoride to obtain liquid aluminum metal. An electric current, at an amperage of up to 600 kA, is passed through the bath.

Once passed through the bath, the electrical current flows into the molten aluminum and is then collected by the bottom of the pot, usually called “cathode”.

We have in house manufacturing facilities to produce tailor made cathode bar-

 Bar Type Length (Range) Cross Section  (range:) Corner Radius
Rectangular Bar Up to 6000 mm 16 mm -300 mm 4-15
Square  Bar Up to 6000 mm 65 mm -80 mm 4-15

We also made special collector bar like wedge shape collector and copper inserted cathode bar.

Use of Copper in Cathode Bar

The use of copper inserts in steel collector bars has proven to be an efficient way of improving the production process. In ideal aluminum electrolysis process, producing 1 MT Aluminum (with 100% efficiency) require 2980 KWH energy. However, in reality, a current efficiency of ≈ 95 – 96 % is observed. Introduction of Copper insert  significantly contributed in DC power reduction.The use of copper inside the cathodes of aluminum reduction cells is becoming a standard .The impact on the cell productivity and specific energy consumption may be significant. Moreover, cell life and recycling may be improved when compared to traditional collector bars design.

CSIL can manufacture all kind of copper insert collector bar assembly including cylindrical, slotted or welded.
