for the design and the process of aluminum reduction cell using inert anode. A see-through cell is constructed to investigate the bubble flow behavior and the electrolyte flow pattern induced by bubbles... of bubble generated at inert anode is smaller than that of bubble generated at graphite anode. Moreover, the bubbles on inert anode are spherical, which was different from those in tubular or disk form......
) results in the generation of the perfluorocarbons (PFCs) CF4 and C2F6 [1]. Especially, the anode effect not only produces high potential greenhouse effect gas, PFCs, but also consumes a number...- discharges and forms F2, which directly reacts with carbon anode and produces two species of fluorine compound gas, CF4 and C2F6. Another view is that an intermediate compound COF2 generated......
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......

in ACD and anode effects, so the energy consumption of the aluminum production can be lowered. On the other hand electrolyte dragged by gas bubbles goes into the grooves, then to the side channel... a prebaked carbon anode with gas discharging grooves at the bottom which could be applied on aluminum reduction cell was conducted. The results reveal that with the help of the grooves, anode gas discharging......
reaction on the anode surface. At the same time, it is the main driver for alumina mixing and bath flow [4]. So, the gas bubbles play an important role in cell operation. The aluminum reduction cell... results [1,9] show that the gas coverage fraction on the anode surface is 30%-60%. In addition, the bubbles release periodically from the anode surface, which will disturb the electrolyte and affect liquid......
inert anode is that gas bubbles, almost like a froth with 0.5-1 mm diameter, evolve at the anode surface. The voltage fluctuations due to bubble evolution for anode is shown in Fig.2. The most value..., the electrolyte is agitated strongly by the oxygen gas bubbles produced at the anode surface. When the gas bubbles move to the cathode surface, they will react with aluminum. In addition, Al4C3......
Behaviors of fine bubbles in the shroud nozzle of ladle and tundishYanping Boo, Jianhua Liu, and Baomei XuMetallurgical Engineering School, University of Science and Technology Beijing, Beijing 100083, China摘 要:<正> Fine bubbles will create when the inert gas is introduced to the high rapid steel stream within the shroud nozzle between ladle......
