Aluminum liquid diversion bag

As a key equipment for flat DC casting, the distribution bag determines the distribution effect and the metallurgical quality of the ingot. Surface cracks, subcutaneous bright crystals, and oxide film defects of the ingot are mostly related to the casting process and distribution. Different specifications and casting processes should match the corresponding distribution bags.

PRODUCTS

Flat-plate crystallizer

The "flat ingot crystallizer" uses graphite plates made of imported permeable graphite material to achieve low-level "LHC" casting, making the surface of the aluminum alloy flat ingot smooth and the segregation layer shallow, which can reduce the amount of ingot milling and improve the overall yield; at the same time
