Product Description

Product Description

This technical scheme is suitable for the melting steel, the equipment is one electric matched with two furnaces, the medium frequency power supply is 12 pulse 3000KW/0.5KHZ. Composition of complete set of equipment: a 4000KVA 6 phase 12 pulse rectifier transformer, a rectifier double KGPS3000K/0.5KHZ parallel resonant inverter, two sets of 5 tons of steel shell with magnet electric furnace, a set of reactive power compensation capacitors, a hydraulic tilting system, a tilting operation table, two sets of water cooling system etc..The transformer is provided by the user itself.
The control system of the equipment using  12   pulse rectifier dual frequency power supply of our newly developed load, using the parallel resonant circuit in the melting power factor can reach more than 0.92, power factor and power efficiency than similar products increased by about 5%, energy-saving products, and can effectively eliminate 5 times, 7 times, 11  times harmonic pollution on power grid.The melting equipment has the characteristics of fast melting speed, energy saving and reducing consumption, and stable and reliable operation.The service life of the complete set of equipment shall be designed and manufactured at less than 25 years.
