To provide a pressurization induction melting device capable of preventing a water cooled cable connecting an induction coil in a melting furnace incorporated in a pressure vessel with external power supply from being deformed even when pressurizing it and circulating cooling water inside the device securely.
This pressurization induction melting device 1 comprises a pressure vessel 2 capable of being tightly closed, an induction melting furnace 6 incorporated in the vessel 2, a gas supply part 16 pressurizing the inside of the vessel 2, and the water cooling type cables 12a, 12b for conducting the induction coil 9 in the melting furnace 6 and high frequency power supply 10. A pair of metallic pipes 20a, 20b having a flange 24 overhanging on an outer peripheral side and a water passing passage 22 passing through along the longitudinal direction pass through an opening 5 in which the cables 12a, 12b pass through the vessel 2. A pair of insulation plates 30, 32 nipping the inside and outside of the flange 24 pass through the metallic pipes 20a, 20b. The insulation plates 30, 32 are fixed to a lid plate 44 which blocks the opening part 5 and through which the metallic pipes 20a, 20b pass.
