INDUCTION HEATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an induction heating apparatus, with which a refractory layer is prevented from the damage caused by the contact with a heating material passing through a heating passage and the stable operation can be executed over a long time. SOLUTION: In the induction heating apparatus, in which the refractory layer 3 is arranged at the inside of a solenoid coil 1 and the heating passage 5 for passing through the heating material 2 is formed at the inside of this refractory layer 3, water cooling pipes 4 are embedded in the inner part of the refractory layer 3 and skid beams 17 supported with these water cooling pipes 4 are projected into the heating passage 5 from the surface of the refractory layer 3 along the carrying direction of the heating material 2.
