Induction Metal Melting Furnace Manufacturer

induction metal melting furnace

Induction metal melting furnace is a kind of melting equipment, which is composed of intermediate frequency power supply, capacitor cabinet, furnace body, mechanical tilting device and so on.

The principle is to use the induction electrothermal effect to complete the metal smelting process. The power supply is generally divided into three types: high frequency (above 10 kHz), intermediate frequency (50 Hz ~ 10 kHz) and power frequency (50 or 60 Hz). According to the size and capacity of the furnace material and the frequency of the power supply, induction furnaces are divided into two categories: cored (mainly closed tank type) and coreless (crucible type).

The circuit of an induction furnace is very similar to a transformer. The primary coil is an induction coil.

There is an iron core in the coil of a cored induction furnace to reduce magnetic flux leakage and improve power factor. The AC magnetic field generated by the coil induces an electromotive force in the charge, generating Joule heat.

The induction metal melting furnace produced and supplied by HANI are widely used in cast iron, stainless steel, copper, aluminum, silicon, special alloys and other fields. Because of its fast melting speed, less burning loss, easy start, automatic stirring, and remarkable power saving, it has been well received by new and old users.

Composition structure:

It is mainly composed of intermediate frequency power supply, capacitor cabinet, furnace body, mechanical tilting device (or hydraulic tilting device), water distributor, crucible mold (or graphite crucible, iron crucible), water cooling cables, connecting copper bars, etc.


Induction Metal Melting Furnace Features

1.The equipment is small in size, light in weight, high in efficiency, and energy-saving;

2.The temperature around the furnace is low, there is less smoke and dust, and the working environment is good;

3.Simple operation process and reliable smelting operation;

4.The heating temperature is uniform, the burning loss is small, the metal composition is uniform, and the casting quality is good;

5.The melting temperature rises quickly, the furnace temperature is easy to control, and the application effect is good in various industries.

The core furnace is characterized by high electric heating efficiency and high power factor, but when it starts to work, there must be a melt in the furnace, and its melting temperature is also low. It is suitable for continuous melting and heat preservation of a single variety such as non-ferrous metals and cast iron.

The coreless furnace is characterized by high melting temperature, easy to change varieties, but low electric heating efficiency, mainly used for smelting and heat preservation of special steel, nickel-based alloys, cast iron, and non-ferrous metals.


The intermediate frequency power supply in the induction metal melting furnace is designed for safe, effective, reliable operation and easy maintenance, so the operator should observe the following precautions in standard operation:

1.Lock all the cabinet doors of the intermediate frequency power supply. Keys are only for qualified maintenance and repair personnel who need to open cabinet doors.

2.When the induction metal melting furnace is started, make sure that the cover plate and other protective covers are always covered.

3.Every time the furnace is opened, it must be inspected before the furnace is opened. Because placed high-voltage equipment poses a potential hazard to personnel in the work area.

4.The main power supply must be cut off before opening the cabinet door or checking the control circuit board.

5.When servicing circuits or components, use only certified testing equipment and follow manufacturer recommended procedures.

6.During the maintenance of the distribution box or induction furnace, it is not allowed to connect the power supply at will, and a warning sign should be placed or locked at the main power supply.

7.Every time the induction metal melting furnace is turned on, check the contact between the grounding electrode wire and the charge or molten pool.

8.The grounding electrode is in poor contact with the charge or molten pool, and high voltage will be generated during operation. Electric shock can cause serious injury or even death.

9.The operator must use conductive tools (check shovel, temperature probe, sampling spoon, etc.) to contact the melt. When touching the melt, turn off the intermediate frequency power supply or wear high-voltage wear-resistant gloves.

10.Operators should wear special wear-resistant furnace gloves for shoveling, sampling and temperature measurement.
