Production process

1. Bauxite crushing: Bauxite is the main raw material for aluminum ingots. It needs to be crushed first to break the ore into small particles.

2. Bauxite leaching: Put the crushed ore into the leaching tank, add hot water and sodium hydroxide to dissolve the aluminate in the bauxite.

3. Filtration: Filter the leachate to filter out the aluminate solution.

4. Oxidation: Transfer the aluminate solution to the reaction tank, add aluminum hydroxide, and oxidize the aluminate solution into aluminum oxide.

5. Electrolysis: Put aluminum oxide into the electrolytic tank, add lithium fluoride and aluminum hydroxide, and perform electrolysis to reduce aluminum oxide to pure aluminum.

6. Casting into ingots: Pour the pure aluminum liquid obtained by electrolysis into a mold, cool and solidify into aluminum ingots.

The above is a detailed introduction to the production process of aluminum ingots. Each link is very important and needs to be strictly controlled and operated to ensure the quality and output of aluminum ingots.

Classification

Aluminum ingots are divided into three types according to their composition: aluminum ingots for remelting, high-purity aluminum ingots and aluminum alloy ingots; according to their shape and size, they can be divided into bar ingots, round ingots, plate ingots, T-shaped ingots and other types.

Several common aluminum ingots

Aluminum ingots for remelting--15kg, 20kg (≤99.80%Al):

T-shaped aluminum ingots--500kg, 1000kg (≤99.80%Al):

High-purity aluminum ingots--10kg, 15kg (99.90%~99.999%Al);

Aluminum alloy ingots--10kg, 15kg (Al--Si, Al--Cu, Al--Mg);

Plate ingots--500~1000kg (for plate making);

Round ingots--30~60kg (for wire drawing).
