pre-baked carbon anode: 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 produced by jining carbon has the property of lower ash content, lower sulfur content,
and higher compress strength .
we can produce pre-baked carbon anode according to requirement of customers
advantage :
1.co2reactivity residue can reach above 91%,air reactivity can reach above 96%;the life-span in cells of aluminium electrolysis is 30-33days , with jining’s anodes the carbon consumption required for producing one ton primary aluminum will reduce by about 30kg than using pre-baked carbon anodes produced by other suppliers .
2.higher thermal shock resistance
thermal exposure : <4*10
heat conductive : <3w/mkl
3.higher current density
3.higher current density
current density : > 0.8a/cm2
4.lower electrical resistivity
electrical resistivity : 55-56μωm
