Aluminum electrolysis anode and preparation method thereof
The invention relates to an aluminum electrolysis anode and a preparation method thereof, the aluminum electrolysis anode comprises the following raw material components: graphite and calcined coke, and the graphite is obtained by carrying out heat treatment on an aluminum electrolysis waste cathode carbon block; wherein in percentage by mass, the content of the graphite is 10%-55%, and the content of the calcined coke is 30%-65%. The graphite replaces part of calcined coke to cooperatively control the resistivity of the aluminum electrolysis anode, so that the resistivity of the aluminum electrolysis anode is less than or equal to 55 mu omega.m, the conductivity of the carbon anode is improved, and the consumption of electric energy generated by electrolysis is reduced.
本申请涉及一种铝电解阳极及其制备方法，所述铝电解阳极的原料组分包括：石墨和煅后焦，所述石墨由铝电解废阴极炭块经热处理得到；其中，以质量分数计，所述石墨的含量为10％～55％，所述煅后焦的含量为30％～65％。石墨代替部分煅后焦，进而协同控制铝电解阳极的电阻率，可以使得铝电解阳极的电阻率≤55μΩ·m，提高了炭素阳极的导电性能，进而降低电解生产电能的消耗。
