of aluminum reduction cells and improving current efficiency of aluminum reduction cells further more, a kind of advanced collector bars and insulation boards was improved. The software ANSYS was used to calculate the current distribution in the 175 kA prebake aluminum reduction cells. The effect of different conditions on current distribution in metal pad of aluminum reduction cells was talked about......

CFD simulation of effect of anode configuration on gas–liquid flow and alumina transport process in an aluminum reduction cellZHAN Shui-qing(詹水清)1, LI Mao(李茂)1, ZHOU Jie-min(周孑民)1, YANG Jian-hong(杨建... 450041, China)Abstract:Numerical simulations of gas–liquid two-phase flow and alumina transport process in an aluminum reduction cell were conducted to investigate the effects of anode configurations......
of the sound absorption mainly depends on the Helmholtz resonator, the microphone as well as cracks of closed-cell aluminum foam. The sound insulation experiments show that the sound reduction index... sound insulation property. Because of its special structure, aluminum foam has great potential application in fields such as noise reduction and sound insulation[12]. In this paper, the authors research......
; Abstract: The influence of aluminum electrolyte component on its temperature is an important issue within the field of aluminum reduction with pre-baked cells. The characteristic correlation between excess AlF3 concentration and aluminum electrolyte temperature was explored through the modeling of heat and mass transfer processes in industrial pre-baked aluminum reduction cells. A coupled......
