The Advantages Of Induction Furnace

The Advantages Of Induction Furnace

According to Wikipedia, the induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tons capacity and are used to melt iron and steel copper, aluminum, and precious metals.

Heating fast, high temperature, easy operation and control, and the less pollution

It is an electric furnace for heating a material using an induced current generated by an induction coil. The material will be placed in a crucible made of refractory material if the metal material is heated. If the non-metallic material is heated, the material is placed in a graphite crucible. Furthermore, the induced current frequency will be corresponding to the increase and result in increased heat when the AC frequency is increased. Induction furnace heating fast, high temperature, easy operation and control, and less pollution of material in the heating process to ensure a high-quality product.

Clean, Energy-efficient

The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal smelting. Most modern foundries use this type of furnace, and now also more iron foundries are replacing cupolas with induction furnaces to melt cast iron, as the former emit lots of dust and other pollutants.

Uniform heating, small table temperature difference, high accuracy of temperature control

The reason why the uniform heating and the small core table temperature difference is simply because of heat generated in the workpiece itself. And the application of the temperature control system can achieve precise control of the temperature to improve product quality and pass rate.

In addition, the medium frequency induction furnace heating device has the advantages of small volume, light weight, high efficiency, excellent quality of hot processing, and environment-friendly. It rapidly replaces the coal-fired stove, gas stove, fuel stove, and ordinary resistance furnace, which is a new generation of metal heating equipment.

Induction Furnace:

Induction heating of metal will provide the heat required for the electrical furnace. An induction furnace will provide a clean, energy-efficient, and well-controlled process of melting when it is compared with other processes. Most of modern foundries use this type of furnace instead of cupolas to melt cast iron as the former emits lots of duct along with other pollutants. 

The capacity ranges from less than one kilogram to a hundred tonnes capacity is used in melting iron, steel, copper, aluminum, and other precious metals. As the process does not use combustion, the material temperature is not higher than the required to melt it. This process prevents the loss of valuable alloying elements. The induction furnace lacks the refining capacity where the charge materials clean the oxidation products and the known composition. The alloying elements may have a chance to lose alloying elements due to oxidation.

The frequency of operation is high and is dependent on the material that is to be melted, and the furnace capacity required. If the volume of the melts is small then it requires a higher frequency. A pre-heated furnace of the melting iron can melt the cold charge by tapping of the readiness within an hour. The power supply range is from 10 KW to 42 KW which melts in size ranges of 20 kg to 65 tonnes of the respective metals. The operating induction furnace can be used by the operators to identify the correct operation and its corresponding power level.
