【China Aluminum Industry Network】 Aluminum profiles are aluminum materials that have different cross-sectional shapes through hot-melting and extrusion. Aluminum production processes include three processes: casting, extrusion and coloring. Among them, the color includes: oxidation, electrophoretic coating, fluorocarbon spray, powder coating, wood grain transfer and other processes. Aluminium profiles are aluminum materials that are produced by hot-melting and extruding aluminum bars with different cross-sectional shapes.

It is learned from the aluminum profile factory that aluminum profiles are usually first processed into cast products, forged products, and foils, plates, strips, tubes, rods, profiles, etc., and then subjected to cold bending, sawing, drilling, assembling, coloring, etc. Processes are made. Therefore, aluminum is the main metal element of aluminum, plus some alloying elements to improve the performance of aluminum profiles. The “Aluminum Materials Knowledge Lecture Room” describes that the aluminum materials are generally used for construction aluminum, aluminum for wood, aluminum for electrical equipment components, aluminum for protruding equipment, and unloading containers, and aluminum for chemical education. .

Aluminum classification method:

First, according to purpose can be divided into the following categories:

1. Doors and windows for the construction of aluminum doors and windows (divided into two kinds of doors and windows and curtain wall).

2. CPU radiator special radiator aluminum profile 3. Aluminum alloy shelf aluminum profiles, their difference lies in the different cross-sectional shape, but are produced by hot melt extrusion.

Second, according to alloy classification:

Jane Gegao partition aluminum factory master said that aluminum profiles can be divided into 1024, 2011, 6063, 6061, 6082, 7075, etc. won the award of aluminum profiles, of which the 6 series is more common. Different brands differ in the various The proportion of metal components is not the same, in addition to commonly used aluminum doors and windows such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, industrial aluminum profiles without a clear model distinction, most production The factory is processed according to the customer's actual drawings.

Third, according to the surface treatment requirements classification:

1. Anodized aluminum material 2. Electrophoretic coating of aluminum 3. Powder sprayed aluminum 4. Wood grain transfer aluminum 5. Planed aluminum (divided into two types of mechanical planing and chemical polishing, in which chemical polishing costs more High and expensive

§ Aluminum production process:

Including casting, extrusion and coloring (coloring includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder coating, wood grain printing, etc.) three processes.

1. Casting is the first step in aluminum production.

The main process is:

(1) Ingredients: According to the specific winning prizes required for production, the amount of various alloy components added is calculated and properly matched with various raw materials.

(2) Smelting: The prepared raw materials are added into the smelting furnace according to the process requirements to be melted, and the impurities and gases in the melt are effectively removed through degassing and deslagging refining means.

(3) Casting: The smelted aluminum liquid is cooled and cast into a variety of round cast rods under a certain casting process condition through a deep well casting system.

2, squeeze:

Extrusion is a means of forming a profile. First, molds were designed and manufactured according to the profiles of the profile products, and the heated round cast rods were extruded from the mold using an extruder. Commonly used grade 6063 alloy, when used in the extrusion also uses an air-cooled quenching process and artificial aging process to complete the heat treatment. Different brands of heat treatable alloys have different heat treatment regimes.

3, coloring (here first talk about the oxidation process)

Oxidation: Extrusion of aluminum alloy profiles, the surface corrosion resistance is not strong, must be surface treatment by anodizing to increase the aluminum corrosion resistance, wear resistance and appearance of the appearance. The high compartment aluminum profiles produced by the Jane Grid high profile aluminum plant are almost all oxidized.

Its main process is:

(1) Surface pretreatment: The surface of the profile is chemically or physically cleaned to expose a pure matrix to facilitate obtaining a complete, dense artificial oxide film. It is also possible to obtain a specular or matt (matte) surface by mechanical means.

(2) Anodizing: After surface pretreatment of the profiles, anodization occurs on the surface of the substrate under certain process conditions to form a dense, porous, strong AL203 film layer.

(3) Sealing: The pores of the pores of the porous oxide film formed after the anodization are closed, so that the oxide film is prevented from contamination, corrosion and abrasion resistance. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores, which can make the appearance of the material besides the colors (silver white), such as: black, bronze, Gold and stainless steel and so on.
