Study on Effect of External Conditons for Hydrogenation Pump on the Dehydrogenation of Molten Aluminum

Abstract:

The effects of external conditions such as short-circuit maching vacuum extraction,short-circuit maching gas carry or different applied voltage on the dehydrogenation by the hydrogen pump with CaZr_0.9In_0.1O_3-α electrolyte at 755°C in aluminum melt were studyed. Among the three external conditions,the dehydrogenation rate of hydrogen pump by applied voltage was fastest,followed by vacuum extraction,then gas carry while the effect of oxygen gas carry was better than the one of argon gas. When the pump was applied 1.5V,the hydrogen content in Al melt was reduced to 0.131ml/100gAl which met conventional aluminum alloys.
