预焙炭阳极通常安装在电解槽上部，强大的直流电流60-300ka通过炭阳极，导入电解液。炭阳极的电阻率为50-70 μΩ.m，加上导杆与接点电阻，正常铝电解生产时，消耗的炭阳极上的电压降为300-500mV,占电解槽电压降的10%-15%。在炭阳极底部接触熔融电解液的部位，发生分解氧化铝的复杂电化学反应(阳极反应)。在碳的参与下，阳极最终产物是CO和CO2。铝电解生产中，炭阳极日平均消耗1-2CM，定期向电解槽上部添加新的阳极糊(对自焙阳极电解槽)或定期更换预焙阳极将(对预焙阳极电解槽)是阳极工作的主要内容，以保持阳极连续正常工作。
The pre-baked carbon anode is usually installed in the upper part of the electrolytic cell, and a strong DC current of 60-300ka is passed through the carbon anode and introduced into the electrolyte. The resistivity of the carbon anode is 50-70 μΩ.m, plus the lead and contact resistance, during normal aluminum electrolysis production, the voltage drop on the carbon anode consumed is 300-500mV, which accounts for 10%-15 of the electrolytic cell voltage drop %. A complex electrochemical reaction (anode reaction) that decomposes alumina occurs at the part where the bottom of the carbon anode contacts the molten electrolyte. With the participation of carbon, the final products of the anode are CO and CO2. In aluminum electrolysis production, the average daily consumption of carbon anodes is 1-2CM. Regularly add new anode paste to the upper part of the electrolytic cell (for self-baked anode electrolyzers) or regularly replace pre-baked anodes (for pre-baked anode electrolyzers) as anode work The main content to keep the anode working continuously and normally.
