Abstract
In this paper, the problem of the rapid rise of cathode voltage drop (CVD) in an aluminum smelter enterprise is analyzed and addressed. Among the factors that lead to the increase of the CVD caused by the long-term unstable power supply load, the reduction of the conductive area of the cathode due to the increase of sludge, crusts, and the growth of side ledge was the main reason, and the sodium penetration and expansion were also inevitable. The CVD could be significantly reduced by adjusting the parameters reasonably and clearing the sludge and crusts on the cathode’s surface of the cells manually, but it was not easy to recover to the initial value. To keep the CVD stable over the long term, it was key to stabilize the controlling parameters, and ensure that the cathode surface temperature was slightly higher than the temperature of the liquid bath.
