The invention relates to a
dehydrogenation process for aluminum or aluminum
alloy flux through utilizing
solid proton conductor and a device. The device comprises an aluminum-
smelting channel, a heating-furnace, temperature-controlling
thermocouple and a
hydrogen-testing sensor. The key points lie in that a
hydrogen extraction device is formed by the mutual connection of a
proton conductor pipe, an
alumina pipe and a
metal pipe, by a contact conductor which is assembled in the
hydrogen extraction device and an another contact conductor with
alumina pipe protective sleeve connecting with an external power switch. The
proton conductor chooses
chemical formula of BaCe 1-XYXO3-a or BaCe1-XSmxO3-a, wherein X is equal to 0.05-0.25 or is made from CaZr 0.9 In 0.1O3-a material. The
dehydrogenation process adopts short-circuit
dehydrogenation under the stirring condition of aluminum or aluminum
alloy flux temperature is 750-800 DEG C, or adopts the combination carrying or
vacuum extraction hydrogenation after short-circuit hydrogenation or adopts applied
voltage to hydrogenate. The hydrogenation effects of the invention are that the content of hydrogen is smaller 0.15ml / 100gAl, and the content of hydrogen is smaller 0.12ml / 100Al for high strength aluminum
alloy flux. The invention has the advantages of simple technology and device, convenient operation, environment-friendly and less investment, which is easy to realize industrialization.
