摘要：

High frequency measurements of voltage were introduced at Elkem Aluminium Lista in order to find the effect of noise from the release of gas bubbles under the anode - bubble noise. On a Soderberg pot the bubble noise represents a fairly large portion of the total pot noise. Hence it is important to understand what impacts the bubble noise in order to understand and control the Soderberg pot in a better way. The bubble noise varies quite a lot over time and between pots. The variations are related to different process conditions. Looking at number of anode problems and carbon dust generation there is a correlation between the bubble noise and the quality of the Soderberg anode. The metal quality is also strongly impacted by a change in the bubble noise. Several process conditions have been investigated, presented and discussed in the paper.
