Aluminum profile production process
Melting is the first process in the production of aluminum. The main processes are:
(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.
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.
