Industrial smelting aluminum is mainly based on electrolysis, electrolytic smelting to pure alumina as raw material using electrolytic aluminum, so the first step in smelting aluminum is the need for Mr. production of alumina. Schneider smelting anti-corrosion coating experts pointed out that the world's alumina is almost always produced by alkali, aluminum electrolysis is based on alumina as raw material, cryolite as the composition of the electrolyte electrolyte, in the 950-970 ℃ conditions The electrolysis of the alumina in the electrolyte melt is decomposed into aluminum and oxygen by electrolysis,The aluminum precipitates in the liquid phase in the carbon cathode, and the oxygen escapes on the carbon anode in the form of carbon dioxide gas. High temperature equipment, high temperature smelting conditions, high temperature aluminum corrosion and corrosion into the industrial smelting aluminum problems, Schneider anti-corrosion coating personnel for many years on the smelting aluminum industry tracking analysis, summarized in the smelting aluminum industry application SNT-506 series aluminum corrosion Summary analysis of the coating.
