Title:
METHOD FOR REMOVING INCLUSION IN MOLTEN METAL AND INCLUSION REMOVING DEVICE FOR MOLTEN METAL
Document Type and Number:
Japanese Patent JP2007144501
Kind Code:
A
Abstract:
To provide a new method and a new device capable of easily removing inclusions in a molten metal such as a molten steel.
A rotary motion generating coil 12 is provided in the outer circumferential face of a cylindrical vessel 11, and further, a coil 13 for generating motion in an axial direction is provided in the outer circumferential face of the vessel 11. Rotary motion is caused to the molten metal S charged inside the vessel 11 by Lorentz force produced from the rotary motion generating coil 12, and motion in an axial direction is caused to the molten metal S by Lorentz force produced from the coil 13 generating motion in an axial direction, thus inclusions included in the molten metal S are flocculated, enlarged, and then removed.
