Recently, the Southwest Aluminum smelting plant successfully trial-produced a large-scale new aluminum alloy square ingot, providing a guarantee for subsequent rolling research. The alloy is a new high-strength and tough aluminum alloy material developed through cooperation between a domestic research institution and Southwest Aluminum, with advantages such as light weight, high strength, good ductility, and low price. However, the casting process of this alloy is difficult, and it is prone to abnormal conditions such as cracking and dross entrapment, leading to the scrapping of ingots.

In order to solve this difficult forming problem, the smelting plant established a task force, attaching great importance to the issue and implementing full-process tracking of the smelting process, strengthening process control, and accumulating data. After multiple failures and continuous adjustment of process parameters, the alloy was successfully trial-produced.
