Abstract:
1. A melting apparatus comprising: a melting tank having an outside plate constructed by metal material and a fireproof member covering the outside plate; and a traveling magnetic field generating unit arranged outside the outside plate of the melting tank, generating a magnetic field traveling along the outside plate in the melting tank so as to agitate a molten metal stored in the melting tank, wherein a melted matter is introduced to the molten metal stored in a melting chamber for melting the melted matter, wherein the traveling magnetic field generating unit comprises: a permanent magnet facing the sidewall of the melting tank; a support member supporting the permanent magnet; and a motor rotatively driving the support member centering on a rotational shaft perpendicular to an outer plate surface of the outside plate, wherein a resistance band having larger electric resistance than the metal material constructing the outside plate is formed at a part of the outside plate of the melting tank facing the permanent magnet, wherein the middle part of the resistance band is arranged at a position in the outside plate of the melting tank facing the rotational shaft, and wherein an end of the resistance band is arranged at a position far from the position in the outside plate of the melting tank facing the rotational shaft.
