Casting is the first process of aluminum production
The main process is:
(1) Ingredients: According to the needs of the production of specific alloy grades, the calculation of the addition of a variety of alloy components, reasonable collocation of various raw materials.
(2) Smelting: will be equipped with good raw materials in accordance with the requirements of the melting furnace melting, and through the removal of gas, slag refining means to melt the impurities, gas effectively removed.
(3) Casting: smelting good aluminum liquid in a certain casting process conditions, through the deep well casting system, cooling casting into a variety of specifications of the round cast rod.
