Cooling aluminum stripCasting and smelting include melting, purification, impurity removal, degassing, slag removal, and the casting process. The main processes are: (1) Ingredient preparation: Calculate the addition amounts of various alloy components according to the specific alloy grade to be produced, and reasonably match various raw materials. (2) Smelting: Add the prepared raw materials into the smelting furnace according to process requirements to melt them, and effectively remove impurities and gases in the melt through degassing and slag removal refining methods. (3) Casting: Under certain casting process conditions, the melted aluminum is poured through a deep well casting system and cooled to cast round ingots of various specifications.
