Aluminum ingots can be divided into three types: aluminum ingots for remelting, high-purity aluminum ingots and aluminum alloy ingots according to different components; according to shape and size, they can be divided into strip ingots, round ingots, plate ingots, and T-shaped ingots.

Several common aluminum ingots

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

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

High-purity aluminum ingot--l0kg, 15kg (99.90%～99.999%Al)

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

Plate ingot--500～1000kg (for plate making)

Round ingot--30～60kg (for wire drawing)

Production Process

The production of aluminum ingots consists of production links such as bauxite mining, alumina production, and aluminum electrolysis.

First, the bauxite is mined, and the bauxite powder is produced by washing, grinding and other processes, and then the alumina is obtained through four complex processes such as roasting. There are three main types of bauxite for alumina production: gibbsite, a Hydraulic stone, boehmite.

Aluminum ingot casting process

In the casting process of aluminum ingots, molten aluminum is injected into the mold. After cooling into a billet and taking it out, the injection process is a key step in the quality of the product. The casting process is also the physical process of crystallization from liquid aluminum into solid aluminum. The process of casting aluminum ingots is roughly as follows:

Aluminium discharge - slag removal - weight inspection - batching - furnace loading - scouring - casting - aluminum ingots for remelting - finished product inspection - finished product inspection weight - storage

Aluminium discharge - slag removal - weight inspection - batching - furnace loading - scouring - casting - alloy ingot - casting alloy ingot - finished product inspection - finished product inspection weight - storage

Commonly used casting methods are divided into continuous casting and vertical semi-continuous casting
