Production process and classification of aluminum ingots
Casting aluminum ingot process is generally as follows:
(1) Aluminum – slag – inspection – batching – furnace loading – refining – casting – remelting of aluminum ingots – finished product inspection – finished product inspection – storage
(2) Aluminum – slag – inspection – batching – furnace loading – refining – casting – alloy ingot – casting alloy ingot – finished product inspection – finished product inspection – storage
Commonly used casting methods are divided into continuous casting and vertical semi-continuous casting
Aluminum ingot according to different composition divided into remelting aluminum ingot, high purity aluminum ingot and aluminum alloy ingot three; According to the shape and size, it can be divided into bar ingot, round ingot, plate ingot, T-shaped ingot and so on.
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 ingot — L0kg, 15kg(99.90%~99.999% AL);
Aluminum alloy ingot –10kg, 15kg(Al–Si, Al–Cu, Al–Mg);
Board ingot -500~1000kg(for plate making);
Round ingot –30~60kg(for drawing).
