Anodic oxidation is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is typically converted into an oxide film. In general, anodic oxidation has a high requirement on the stability of current, and when the current passing through the anodic oxidation is unstable, the thickness of the generated oxide film is uneven, and the oxidation quality is reduced. For the oxidation on the surface of a large-sized section bar, the transfer of the section bar among different medicine tanks is generally realized through the lifting of a portal frame, and when the portal frame places the section bar into an anodic oxidation tank, the poor contact of a hanger, unstable current and uneven thickness of a generated oxide film can be caused due to the existence of factors such as movement errors, structural deformation, oxidized connection parts and the like.

Next, when the profile is oxidized, the resistance of the oxide film increases the temperature of the electrolyte in the vicinity, and the change in temperature directly affects the dissolution rate of the oxide film and thus the thickness of the oxide film, and in general, anodic oxidation needs to be performed at a low temperature. Generally, the upper end of the oxidation tank is connected with a heat exchanger, and electrolyte after temperature rise flows back to the oxidation tank after being cooled by the heat exchanger to maintain the low temperature state of the oxidation tank, but for a large oxidation tank, long time is required for uniform cooling and heating, the placement positions of the portal frames are approximately the same when the profile is lifted, and the temperature difference exists between the portal frames and the nearby cooling liquid, namely, the portal frames are positioned at the positions with uneven temperature each time the profile is placed, so that the quality of anodic oxidation is influenced.
