The pre-baked anode carbon block is usually installed in the upper part of the electrolytic cell, and a strong direct 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, accounting for 10%-15 of the electrolytic cell voltage drop %. At the part where the bottom of the carbon anode contacts the molten electrolyte, a complex electrochemical reaction (anode reaction) that decomposes alumina occurs. With the participation of carbon, the final products of the anode are CO and CO2. In the production of aluminum electrolysis, the average daily consumption of anode carbon block is 1-2CM. Regularly add new anode paste to the upper part of the electrolytic cell (for self-baked anode electrolyzer) or regularly replace the pre-baked anode (for pre-baked anode electrolyzer) as anode work The main content to keep the anode continuously working normally.
