1. Melting and casting is the first process of aluminum profile} production. The main processes are as follows: (1) batching: calculate the addition amount of various alloy components according to the specific alloy brand to be produced, and reasonably match various raw materials. (2) Smelting: add the prepared raw materials into the smelting furnace for melting according to the process requirements, and effectively remove the miscellaneous slag and gas in the melt by means of degassing and slag refining. (3) Casting: molten aluminum is cooled and cast into round cast rods of various specifications through deep well casting system under certain casting process conditions. 2. Extrusion: extrusion is the means of profile forming. Firstly, the die is designed and manufactured according to the profile product section, and the heated round cast rod is extruded from the die by extruder. The common grade 6063 alloy also uses an air-cooled quenching process and subsequent artificial aging process during extrusion to complete heat treatment strengthening. Different grades of heat treatable strengthening alloys have different heat treatment systems.
