<p>In the transverse type induction heating apparatus in which a material 1 to be rolled is heated by inductors 2 and 3 to which electric power is supplied from an AC power source 4, iron core widths of the inductors 2 and 3 in a plate width direction of the material 1 to be rolled are made smaller than a plate width of the material 1 to be rolled, they are disposed on a plate width center line of the material 1 to be rolled, and when a current penetration depth is made delta (m), a specific resistance of the material 1 to be rolled is made rho ( OMEGA -m), a magnetic permeability of the material 1 to be rolled is made mu (H/m), a heating frequency of the AC power source 4 is made f (Hz), a circular constant is made pi , and a plate thickness of the material 1 to be rolled is made tw (m) , the heating frequency of the AC power source 4 is set to cause the current penetration depth delta of expression (1) to satisfy expression (2) <DF NUM="(1)"> delta = ä rho /( mu .f. pi )ü<1/2> </DF> <DF NUM="(2).">(tw/ delta ) < 0.95 </DF> <IMAGE></p> |
