导流式铝电解槽电-热平衡计算建模与应用
Modeling and application for calculation of electric-thermal balance in a drained aluminium reduction cell
摘要
Abstract
The model for calculating of electric-thermal balance in a drained aluminium reduction cell was established by combining experiential formula and numerical simulation. A 114.5 kA drained cell was calculated by using this model. And the distribution of the electric-thermal field was obtained by the finite element analysis software. The results show that under the given process condition, the anode-cathode distance can drop to 2.75 cm, the cell system voltage drops to 3.312 V and the energy efficiency reaches 53.63%, which shows the great potential of energy saving for the drained cell. In addition, a well shaped ledge with reasonable thickness is also acquired in the investigated cell. In stable condition, the ledge is 12 cm in thickness. The research results can provide reference for design of the drained cell.关键词
