Induction melting furnaces with manual control

Induction smelting units are designed for melting of steel, cast iron, aluminum, copper and their alloys, and also for manufacture of special alloys.

Capacity: 0.1 to 3 t

Frequency: 250 to 2400 Hz

Power: 100 to 3200 kW

Set of melting system:

Induction melting furnace (one or two smelting units)
Induction power supply unit
Converter remote control panel
Line transformer
Electro-thermal water-cooled capacitor unit
Lining status control unit
Weighing system
Temperature sensing system
Furnace angular position hydraulic actuator
Hydraulic actuator control panel
Cooling system with heat-exchanger “water-to-water”
Cooling system control unit

Induction melting furnace includes the following:

Furnace casing
Furnace braces with brackets for casing and hydraulic cylinders
Hydraulic cylinders of furnace angular position
Water-cooled magnetic conductors are to be a core made of electric steel. Magnetic conductors have water cooling in the area of inductor outs. They equipped with fuse carriers for improvement of inductor insulation resistance.
Support unit of water-cooled current distributors.
Furnace cover with flange for coal and gas removal system actuation deflecting by hydraulic actuator

Power supply unit comprising:

Generator for supplying of induction heating devices TFC series
Digital control system of power supply unit
Adjusting throttle
Water cooling system
Set of maintenance documentation
SPTA

Power supply unit was specially designed for operation in set of induction melting systems. It incorporates the developments of ТрПЧ and ТПЧ series that company TET ESTEL conducting since 1968. Converter is equipped with new microprocessor control system providing control from front converter panel and operator panel as well.

Major advantages of generators are in their adjusting features:

output voltage variation range is 20 to 100% vs rated one
range of load power adjustment is 3 to 100% vs rated one

Designed to comply with RoHS and REACH requirements.

To ease the designing, decrease losses and space saving in melting area the company TET ESTEL has developed a series of single-block power supply unit for induction furnaces integrating TFC converter , capacitor bank, cooling system and control.
