A Modelling of Heat Losses in Aluminium Reduction Cell With Slotted Anodes

Abstract

The heat losses of aluminium reduction cells depend strongly on the heat transfer coefficients between the bath and side ledge or anodes. Using of anodes with slots can greatly change heat transfer. In order to investigate the heat loss dynamics in reduction cells with slotted anodes, a modeling of heat transfer coefficients in cells was firstly undertook. This enables understanding of how slotted anode changes heat dissipation from the bath. Then, a thermal field was been calculated by using heat transfer coefficients obtained in the first step. All these studies were carried out with 500kA cells.
