| Abstract: |
| According to the present situation of high aluminium electrolytic power consumption,take 186kA series aluminium electrolytic cell anode as rearch subjects.Under the condition of normal production,X,Y and Z three domestic factory’s anode carbon block voltage drop,steel-carbon voltage drop, steel stub voltage drop and explosive welding voltage drop were measured and compared to analyse and rearch on the reducing potential of pre-baked anode voltge drop.The results show that,,there are a maximum difference up to 12.2mV among X ,Y and Z anode explosive welding average voltage drops, a maximum difference up to 19.8mV among steel stub average voltage drops, a maximum difference from 9mV to 26mV among steel-carbon average voltage drops,and a maximum difference up to 275.8mV among carbon block average voltage drops; Carbon block voltage drop has at least 33.4mV reducing potential,steel-carbon voltage drop at least 34.2mV, steel stub voltage drop at least 8.7mV, explosive welding voltage drop at least 7.9mV;X fatory’s anode voltage drop has reducing potential from 77.4 to 82.9mV,Y fatory’s anode voltage drop 77mV,and Z fatory’s anode voltage drop 83.4mV. |
