ABSTRACT:
A device for contactless, vertically downwards continuous casting of metals in an electromagnetic alternating field, has an inductor and an electrically conductive, non-ferromagnetic screen that tapers downwards and features at a vertical distance 9 from this screen an electrically conductive, non-ferromagnetic counter screen that tapers upwards, the distance 9 between the said screen and counter screen being at least 2 mm, at most equal of the height of the inductor and in a continuous process which employs this device the circulation of the melt in the molten head of the ingot is reduced at least in the steady-state phase of casting. The process is particularly suitable for continuous casting aluminum alloys having a magnesium content of at least 2%.
