Title:
PROCESS FOR PRODUCTION OF ALUMINUM ALLOY CAST BAR, CONTINUOUS CASTING DEVICE, AND ELECTROMAGNETIC STIRRING COIL FOR CONTINUOUS CASTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/158477
Kind Code:
A1
Abstract:
In the production of an aluminum alloy cast bar (R) for semi-melt-molding processing by carrying out continuous casting while electromagnetically stirring an molten aluminum alloy (M) by means of an electromagnetic stirring coil (5), the aluminum alloy cast bar is produced using a hypoeutectic Al-Si-based alloy comprising 3.0 to 10.0 mass% of Si and a reminder made up by Al, 1.0 mass% or less of Fe, a trace amount of an additive and unavoidable impurities as a material for the aluminum alloy cast bar and using an electromagnetic stirring coil in which the magnetic pole of the rotating magnetic field that is generated upon the conduction of a three-phase alternate current electric power to multiple coil elements (C) is bipolar as a whole as the electromagnetic stirring coil (5).
