Definitions
- low frequency electric current is applied to the coil, and the mold is provided with a replaceable ring at an upper portion inside the mold.
- the mold has a circular or rectangular cross-section, and the coil is provided to surround the mold.
- the apparatus further comprises a cooling nozzle between the mold and the electromagnetic stirring device.
- FIG. 3 is a conceptual diagram illustrating an apparatus for continuous casting of magnesium billets or slabs using an electromagnetic field in accordance with a second embodiment of the present invention, which comprises a circular mold, and a coil adapted to allow high frequency electric current to be applied thereto;
- FIG. 4 is a plan view illustrating the apparatus in accordance with the second embodiment, which comprises the circular mold, and the coil adapted to allow the high frequency electric current to be applied thereto;
- the electromagnetic force generated within the molten metal 15 has a gradient that the electromagnetic force is large on the surface of the molten metal, and small at an inner portion of the molten metal, and causes the molten metal to be stirred within the mold, thereby enhancing the inner structure of the billet.
- the high frequency electromagnetic field has a very small penetration depth in the molten metal, it is difficult to apply the high frequency electromagnetic field into the mold 101 made of copper. Thus, the slits 109 are machined in the mold 101 to allow the high frequency electromagnetic field to be effectively applied to the molten metal 105.
- the low frequency electromagnetic field has a large penetration depth in the molten metal, it can be applied to the molten metal within the copper mold. Thus, it is not necessary to form the slits in the mold.
- Such induced current serves not only to heat the molten metal 105 via Joule heating, but also to generate electromagnetic force in the molten metal 105 via interaction with the magnetic field.
- the electromagnetic force increases a curvature of a surface S of the molten metal 105 (see Fig. 3) where the molten metal 105 contacts the mold 101, while reducing a contact pressure between the as-cast billet or slab 106 and the mold 101.
