General profile production process: .
It mainly includes three processes: casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoresis coating, fluorocarbon spraying, powder spraying, wood grain transfer, etc.).
1. Casting is the first process of aluminum production.
The main process is: .
(1) Ingredients: According to the specific alloy grades to be produced, calculate the addition amount of various alloy components, 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 slag and gas in the melt are effectively removed by degassing, slag removal and refining.
(3) Casting: Under certain casting conditions, the molten aluminum is cooled and cast into round cast rods of various specifications through a deep well casting system.
2. Extrusion: .
Extrusion is a means of profile forming. First, according to the section design of the profile product, a mold is manufactured. The general profile uses an extruder to extrude the heated round cast rod from the mold. The commonly used grade 6063 alloy is also extruded. An air-cooled quenching process and subsequent artificial aging process are used to complete heat treatment strengthening. Different grades of heat-treatable-strengthened alloys have different heat treatment systems.
3. Coloring (here we mainly talk about the process of oxidation).
Oxidation: The surface of the extruded aluminum alloy profile is not strong in corrosion resistance. It must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum profile. The high-compartment general-purpose profiles produced by the factory are almost all oxidized.
The main process is: .
(1) Surface pretreatment: The surface of the profile is cleaned by chemical or physical methods, and the pure substrate is exposed to facilitate the acquisition of a complete and dense artificial oxide film. light) surface.
(2) Anodizing: Under certain process conditions, the surface of the pretreated profile will undergo anodization on the surface of the substrate to form a dense, porous, and strong AL203 film layer.
(3) Sealing: The pores of the porous oxide film formed after anodization are closed, so that the oxide film is anti-pollution, anti-corrosion and wear-resistant, and the oxide film is colorless and transparent. Strong adsorption, some metal salts are adsorbed and deposited in the membrane pores, which can make the surface of the profile show many colors other than the original color (silver white), such as: black, bronze, golden yellow and stainless steel.
Because of the various advantages of aluminum doors and windows, many people have installed aluminum doors and windows in their homes. These doors and windows are processed by aluminum doors and windows equipment. How are the profiles for aluminum doors and windows processed? This is a question that many people want to know. When buying, it is related to the chemical composition of aluminum products and the content of aluminum, just as people generally pay attention to the composition of food and cosmetics, so now let's learn how industrial aluminum equipment is processed.
Before the general profile processing, it is necessary to add other metals to the pure aluminum material to melt into the aluminum alloy product model required by our products, and then make various molds according to the profile requirements of industrial products. The process of making molds is very important. , related to the size, shape and color of industrial aluminum equipment, etc.
After having the mold and the aluminum alloy, the aluminum alloy raw material can be put in the mold and extruded into the shape of the mold, so that the industrial aluminum equipment has the shape we need, and the manufactured industrial aluminum equipment will be labeled with a name. Labels with remarks such as shelf life and expiration date, and then attach beautiful packaging, and then wait for the factory to sell, general profiles.
