Title:
METHOD FOR CONTINUOUSLY CASTING MOLTEN METAL AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JP3896659
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To execute a stable casting operation by reducing the leakage of magnetic flux in a method of continuous casting while executing molten metal flow control by using a superconducting coil.
SOLUTION: Static magnetic field is impressed in a mold 1 with the superconducting coil (c) arranged at faced side walls 1a, 1b of the mold for continuous casting to control the molten metal spouting stream flowing out from an immersion nozzle 2. Further, the magnetic flux dispersed from a magnetic pole at the far side from the mold in the superconducting coil (c) is shielded with an electromagnetic coil 6 generating the magnetic field having the reverse polarity to the superconducting coil (c) arranged facing to the magnetic field of the super conducting coil (c).
