Title:
CONTINUOUS CASTING APPARATUS BY INDUCTION HEATING HAVING MAGNETIC FLUX SHIELDING DEVICE AND MELTING FURNACE
Document Type and Number:
Japanese Patent JP3122321
Kind Code:
B2
Abstract:

PURPOSE: To restrain the leakage of magnetic flux to the outside, to prevent the heating of an outside structural member and to improve the electric power efficiency by arranging a magnetic material-made magnetic shielding member so as to surround the upper and the lower both sides and the outer peripheral side or the induction heating coil of an induction heating device.
CONSTITUTION: The magnetic material of laminated electrical steel sheet, ferrite, etc., is used and U-shaped or straight cylindrical, polygonal magnetic shielding member 1 of the cross section in the axial direction is manufactured and the induction heating coil 12 arranged in temp. holding and stirring part 19 of a continuous casting apparatus in the inner surface is arranged. Further, the upper and the lower end surfaces 1a, 1b of the magnetic shielding material 1 are put with a copper or a copper alloy-made round plate or polygonal plate 2, 3 and combined and fixed to a copper-made frame 4 having the fixed gas with this magnetic shielding material 1, with bolts 5 and nuts 6. Then, the magnetic shielding member 1 has the structure arranged at a prescribed equal interval in the circular direction of the outside of the heating coil 12.
