Pre-baked anode


Detail

Pre-baked Carbon Anode

Manufacturing: made from petroleum coke ,coal tar pitch, through mixing ,forming and baking process , be used as anodes in cells of Primary Aluminum Smelter . Pre-baked Carbon Anodes has the property of lower Ash content, Lower Sulfur content and Higher Compress strength .
 

Advantage :

1. CO2 Reactivity Residue can reach above 91%,Air Reactivity can reach above 96%; the life-span in cells of  aluminum electrolysis is 30-33days.

2.Higher thermal shock Resistance

Thermal Exposure : <4*10, Heat Conductive : <3W/mkl

3.higher current density: current density : > 0.8A/cm2

4. lower Electrical Resistivity: Electrical Resistivity : 55-56μΩm

 

Common size: 1500×660×550mm/1450×660×540mm/1300×700×550mm/960×840×510mm/980×820×530mm  

* special size can be tailored as per customer’s drawing.
