<p>PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating means which can selectively heat corner parts of a heated object and, therefore, prevent or correct cooling of the corner parts of the heated object after being taken out of the oven. SOLUTION: Iron cores 2 are formed so as to form magnetic field lines between magnetic poles 3, 4 in symmetry with a heated object, and solenoid type coils 5 are wound around the iron cores 2 to make up an electromagnetic induction heating part 7 between the magnetic poles 3, 4. A heated object 6 by way of a square timber is arranged so that diagonal directions of corner parts C1, C3 to be heated from among the four corner parts C1, C2, C3, C4 be across the direction of magnetic flux generated at the heating part 7, and is moved toward longitudinal direction of the heated object 6 to selectively heat the corner parts C1, C3 in the electromagnetic induction heating device 1.</p> |
