| 摘要 |
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 selection step for selecting, among a plurality of silicon masses 12 containing phosphorus as an impurity, silicon masses 12A which do not have visually peculiar parts formed by aggregation of phosphorus on the surface thereof using a selection means, a molten metal formation step for obtaining molten metal by introducing, into a melting furnace, an alloy material including at least an aluminum material and the silicon masses selected in the selection step and which do not have visually peculiar parts, and a casting step for obtaining a silicon-containing aluminum alloy ingot by casting the obtained molten metal. |
