Introduction and application

This is the device converting three phase power current into single-phase intermediate frequency current and enabling metal to produce eddy current loss through the electromagnetic field induction to achieve heating and melting and is applicable to melting, heating or holding of steel, copper, aluminum, zinc, tin, nickel, silver and other ferrous or non ferrous metal and alloy material, as well as heating treatment prior to forging, sintering and tube- bending forming in casting and melting industries.

Performance and features

1. Zero-voltage scanning soft start or stop at any time under any state without impact on power supply;

2. Speedy melting, low production cost, low pollution, conforming to environmental protection requirement;

3. Melting directly from low temperature, available for fully emptying of solution, easy change of category of melting material;

4. Flexibly adjustable power, easy and continuous smooth adjustment, easily controllable temperature, low oxidization loss, uniform metal content;

5. Furnace shell with cast aluminum ally or steel shell construction, small footprint, easy overturn body, available for selection of electric, manual, hydraulic or other overturn mode as needed;

6. Contravariant automatic regulation circuit available for matching of load impendence automatically, maintaining good operation without regulation or compensation of capacitance; power supply with fault diagnosis facilitating service.
