Abstract (en)
[origin: EP2929958A1] Provided is a method of producing a silicon-containing aluminum ingot capable of preventing filter clogging that requires suspension of casting, suppressing aluminum loss, and reducing a content rate of phosphorus as an impurity in the obtained silicon-containing aluminum alloy ingot. The production method of the present invention includes a water-rinsing step for subjecting a silicon mass containing phosphorus as an impurity to a water-rinsing treatment, a molten metal formation step for obtaining molten metal by introducing, into a melting furnace, an alloy material including at least the silicon mass obtained through the water-rinsing step and an aluminum material and and melting the alloy material, and a casting step for obtaining a silicon-containing aluminum alloy ingot by casting the obtained molten metal.
