ABSTRACT:
In a transverse induction heating apparatus in which a material to be rolled is heated by inductors to which electric power is supplied from an AC power source, iron core widths of the inductors in a plate width direction of the material to be rolled are smaller than plate width of the material to be rolled, they are disposed on a plate width center line of the material to be rolled, and when a current penetration depth is δ(m), specific resistance of the material to be rolled is ρ(Ω-m), magnetic permeability of the material to be rolled is μ(H/m), heating frequency of the AC power source is f (Hz), and plate thickness of the material to be rolled is tw (m), the heating frequency of the AC power source is set so thatin-line-formulae description="In-line Formulae" end="lead"?δ={ρ/(μ·f·π)}1/2and (tw/δ)<0.95.in-line-formulae description="In-line Formulae" end="tail"?
