Iron Melting Furnace

Intelligent Control System

Adopts parallel resonance, the control circuit is fully integrated, and the medium frequency power supply adopts zero voltage soft start. The power can be adjusted arbitrarily, the panel control interface is simple, and the internal intelligent control is convenient for operation.

Working Principle

The medium frequency induction melting furnace is a frequency conversion device that converts three-phase power frequency current into single-phase medium frequency current. This alternating magnetism creates resistance in the metal, achieve the purpose of heating and melting the metal.

Structural Features

The medium frequency induction melting furnace is mainly composed of induction heating power supply, induction furnace body, capacitance compensator, reducer, induction coil and crucible made of refractory materials in the induction coil.

Induction Heating Power Supply
The aluminum shell furnace adopt medium frequency induction heating power supply, which has multiple protection functions including over-current protection, water shortage protection, over-heat protection, over-voltage protection, short-circuit protection, phase failure/loss protection and other alarm functions. It will automatically alarm in case of faults, greatly improving the reliability of the equipment.

Induction Melting Furnace
The aluminum shell furnace body is made of alloy aluminum foundry casting to ensure the strength of the furnace body; the thick-walled induction coil uses T2 standard copper tube, which can provide more smelting energy, and the open space between the turns of the induction coil improves the electrical efficiency;

Reduction Box
The furnace body is easy to turn and dump, the metal composition is uniform, and the temperature is uniform and easy to control; the furnace body is easy to turn and dump, the metal composition is heated evenly, and the temperature is easy to control.

Induction Coil
For induction coils of various specifications, the wall thickness and specifications of copper tubes are reasonably selected to improve the utilization rate of electric energy; the inter-turn gap of the induction coil is convenient for maintenance and is conducive to the release of water vapor.

Less Interference To The Grid

The medium frequency induction melting furnace adopts the method of three-phase full bridge rectification and direct current superposition, which increases the output voltage, reduces the high-order harmonics, and has little interference to the power grid. At the same time, the transformer heats up and the loss is low.

Eco-Friendly Equipment

The temperature around the furnace is low, the operation of the induction melting furnace has less heat radiation, less smoke and dust. Induction furnace technology provide a good working environment for workers.
