Title:
METHOD FOR PRODUCING SILICON-CONTAINING ALUMINUM ALLOY INGOT
Document Type and Number:
WIPO Patent Application WO/2014/091939
Kind Code:
A1
Abstract:
Provided is a method for producing a silicon-containing aluminum alloy ingot with which it is possible to prevent filter clogging that requires the suspension of casting, to suppress aluminum loss, and to reduce the content by percentage of phosphorus, which is an impurity in the obtained silicon-containing aluminum alloy ingot. This production method comprises: 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 smelting furnace, an alloy material including at least an aluminum material and said silicon mass obtained through said water-rinsing step, and melting said alloy material; and a casting step for obtaining a silicon-containing aluminum alloy ingot by casting the obtained molten metal.
