Description
Technical field
This utility model relates to aluminium electroloysis and purifying aluminium alloy melt field, particularly relates to a kind of anode effect not producing hydrogen and alumina inclusion and processes device.
Background technology
Aluminum is the second largest structural metallic materials being only second to iron and steel, and aluminum melt quality affects aluminum product quality, and clean liquid metals is the guarantee obtaining fine aluminum goods.Hydrogen is the gas that uniquely can be dissolved in aluminum melt in a large number, and aluminum liquid solidifies defects such as precipitating out pore produced by hydrogen, loosen, directly affects the quality of aluminum products, performance, is the reason of air blister defect in annealing and solution treatment aluminium alloy.Al2O3It is mingled with the key factor being to affect aluminum melt metallurgical quality, destroy the seriality of aluminum substrate, reduce matrix strength, worsening aluminum profile extrusion performance, decay resistance and Resisting fractre toughness, the germinating for fatigue crack provides core (paper " electrolysis process influence research to electrolytic aluminium liquid quality " referring to He Yongdong, Zhang Xinming).
In electrolytic aluminium liquid, alumina inclusion content is typically in 1%-2%, hydrogen content average out to 0.34ml/100gAl in your aluminum actual measurement electrolytic aluminium liquid.For these reasons, in the initial last 100 years of Hall-Ai Lute molten-salt electrolytic aluminum, people cannot directly utilize high-temperature electrolysis aluminum liquid casting ingot casting always.Along with technological progress, the abbreviated system directly utilizing high-temperature electrolysis aluminum liquid production strand is used widely, the hydrogen produced in electrolytic process and the oxide inclusion pollution to aluminum melt, become the main contributor (paper " metallurgical heredity of aluminum and Dissolved H in Liquid Al-Si Alloy and oxide inclusion " referring to He Yongdong) affecting aluminum melt metallurgical quality.
He Yongdong, Zhang Xinming, Chen Mingan etc. are at its paper " Al in electrolytic aluminium liquid2O3The formation mechenism of field trash " in point out: anode effect be on carbon anode interface precipitate out CO2The current blockade process that gas can not be discharged in time and be caused, the frequency that effect occurs is relevant with the cold-hot condition of alumina concentration fluctuation in electrolyte, electrolysis bath.Effect itself is not resulted in aluminum liquid containing assorted, hydrogenation, and putting out effect operation can increase hydrogen and oxide inclusion content in electrolytic aluminium liquid to a certain extent.In actual production, often adopt compression air and wet batten extinguishes effect, first in electrolyte, add enough Al2O3, wetter batten is inserted in aluminum liquid-electrolyte, there is strong dehydration, the H of generation in wet batten2O and CO2Aluminum liquid is stirred by gas, and aluminum liquid, through air film barrier layer and anode in short circuit, reaches to extinguish the purpose of effect.Or high-pressure blast is directly blown in aluminum liquid, aluminum liquid produces strong wallop, stir aluminum liquid and form short circuit, reach to extinguish the purpose of effect.Compression air or wet batten dehydration product can react with high temperature aluminum liquid, generate substantial amounts of Al2O3It is mingled with and hydrogen:
4Al+6H20=2 (α-Al2O3)+6H2-395.7KJ/mol；
2Al+3CO2=(α-Al2O3)+3CO-550.38KJ/mol.
4Al+3O2=2Al2O3-1109KJ/mol；
Fig. 1 for putting out in effect process, H2O、CO2The interfacial oxide film layer that bubble produces with aluminum effect and hydrogen interaction process schematic diagram, the H of generation2、CO、CO2Contact with the oxide-film of bubble surface Deng gas, oxidized film inwall adsorbs, high temperature aluminum liquid flows into bubble by oxide-film gap, causes aluminum liquid hydrogen and alumina inclusion to pollute (paper " in electrolytic aluminium liquid hydrogen evolution Exploration of Mechanism " referring to He Yongdong, Zhang Xinming).Traditional method is adopted to extinguish the process of effect, it is actually the process of slag making in aluminum liquid, gas making, the electrolytic aluminium liquid major reason that produces that hydrogen and aluminium oxide pollute, and there is manipulation strength height, environmental pollution is big, material consumption is high, easily form the deficiencies such as a large amount of precipitation of alumina at bottom land.
