The 7075 seamless aluminum tube melting process mainly includes melting, purification, impurity removal, degassing, slag removal and casting processes. The main process is:
(1) Ingredients: Calculate the amount of various alloy components according to the specific number of products required for production, 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.
