Depolarised gas anodes for aluminium electrowinning G. M. HAARBERG1, E. KVALHEIM1, A. P. RATVIK1, S. J. XIAO1, T. MOKKELBOST2 1. Department of Materials Science and Engineering, Norwegian... a higher anode potential. An alternative approach is to use a natural gas or hydrogen gas anode to reduce the CO2 emissions and lower the anode potential. Preliminary laboratory experiments were carried......
Simulation of mold filling and prediction of gas entrapment on practical high pressure die castings ZHAO Hai-dong(赵海东), BAI Yan-fei(白砚飞), OUYANG Xiao-xian(欧阳晓贤), DONG Pu-yun(董普云) State..., a method for gas entrapment was established by tracking flow of entrapped gas. The model and method were applied to practical ADC1 high pressure die castings. The gas entrapment prediction was compared......
