Analysis and experimental research on differences and regional concentration control of alumina in the same aluminum electrolytic cell
This paper conducts an analysis on differences in the same 500 kA electrolytic cell operated by a certain company.It is found that there are cer-tain gradients and differences in the distribution of bath temperature,superheat,and alumina concentration inside the same electrolytic cell.Research and industrial tests have been conducted on the regional control technology of alumina concentration in response to differences within the same electrolytic cell.A 6-month industrial test showed that the current efficiency of the test cell increased by 0.51％,the DC power consumption per ton of aluminum de-creased by 62 kWh/t-Al,and the anode effect coefficient decreased by 40％.It can be seen that the alumina regional concentration control technology has considerable energy-saving and efficiency creation potential.
