cargoes insteadAluminum profile production process:It mainly
includes three processes of casting, extrusion and coloring
(coloring mainly includes: oxidation, electrophoretic coating,
fluorocarbon coating, powder coating, wood grain transfer, etc.).1.
Melting and casting is the first process of aluminum production.The
main process is:(1) Ingredients: Calculate the amount of various
alloy components according to the specific alloy grades that need
to be produced, and reasonably match various raw materials.(2)
Smelting: The prepared raw materials are added to the melting
furnace for melting according to the process requirements, and the
impurities and gases in the melt are effectively removed by
degassing and slag refining means.(3) Casting: The molten aluminum
liquid is cooled and cast into various round casting rods under a
certain casting process condition through a deep well casting
system.2. Extrusion:Extrusion is the means of profile forming.
Firstly, the mold is designed and manufactured according to the
section of the profile product, and the heated round cast rod is
extruded from the mold by an extruder. The commonly used grade 6063
alloy is also subjected to an air-cooling quenching process and an
artificial aging process after extrusion to complete the heat
treatment strengthening. Different grades of heat treatable
reinforced alloys have different heat treatment regimes.3. Coloring
(here mainly on the oxidation process)Oxidation: The extruded
aluminum alloy profile has a low surface corrosion resistance and
must be surface treated by anodizing to increase the corrosion
resistance, wear resistance and appearance of the aluminum. The
high compartment aluminum profiles produced by the Jane's high
compartment aluminum profile plant are almost all oxidized.The main
process is:(1) Surface pretreatment: The surface of the profile is
cleaned by chemical or physical means to expose a pure substrate to
facilitate the obtaining of a complete and dense artificial oxide
film. It is also possible to obtain a specular or matt (matte)
surface by mechanical means.(2) Anodizing: After surface
pretreatment, under certain process conditions, the surface of the
substrate is anodized to form a dense, porous, strong adsorption
AL203 film.(3) Sealing: The pores of the pores of the porous oxide
film formed by anodization are closed, so that the oxide film is
prevented from being contaminated, and the corrosion resistance and
wear resistance are enhanced. The oxide film is colorless and
transparent. By using the strong adsorption property of the oxide
film before sealing, some metal salts are adsorbed and deposited in
the pores of the film, so that the appearance of the profile shows
many colors other than the natural color (silver white), such as
black, bronze, Gold and stainless ste /* January 22, 2024
