What is an Induction Furnace?
An induction furnace is a type of electric furnace where heat is applied by induction heating of metal. These furnaces utilize an alternating electromagnetic field to generate heat directly within the metal. Typically, they operate using medium-frequency alternating current (AC), ranging from a few hundred Hertz (Hz) to several kilohertz (kHz). The core component is a coil through which an alternating current is passed, creating an electromagnetic field that induces currents within the metal, causing it to heat up and melt.
The Advantage of Induction Furnace
Induction furnace plays a vital role in modern steelmaking process, especially for those projects with limited budget and restricted power facilities. Compared with electric arc furnace steelmaking, it has the following advantages, so it is widely adopted by many customers.
- Less impact on the power grid
- Less manpower and knowledge required for operation
- Lower investment and production costs
- Lower demand and cost of auxiliary materials
The Restriction of Induction Furnace
However, the limitations of induction furnaces must be acknowledged. One of these is the lack of refining capabilities for decarburization and dephosphorization. This means that in a pure IF process, the quality of the final product depends on the initial quality of the scrap used. Therefore, it can be challenging for projects with limited scrap supply.
To address the inherent limitations of induction furnaces, Shanghai Metallurgical Equipment Group has developed an innovative solution: the induction furnace + LOD + LRF system. This breakthrough technology retains the advantages of low cost and easy operation while significantly improving the refining capacity to almost the same as the electric arc furnace process, making the induction furnace no longer “picky”.
