Why Electromagnetic Heat In A Steel Furnace Is Better

Any industry that uses steel for a variety of different purposes, whether it is a steel plant, the aerospace industry, or a company that manufactures automobiles with steel parts, needs a steel furnace to melt the steel so that it can be used for whatever purpose it is needed.

These furnaces make use of electromagnetic induction that allows the furnace to heat and melt the steel. By using electromagnetic heat, or induction, this machine is both energy-efficient and environmentally friendly. Production losses are reduced, and production is also more controllable than with other technologies.

How electromagnetic heat works

Rather than burning fuel to produce the needed heat, these furnaces use electricity. An AC current is put through a coil which then produces a constant electromagnetic field. This field creates a secondary current that is channeled through the main AC circuit. This circuit then generates the needed heat through various processes.


An induction melting steel furnace uses IGBT technology to deliver the benefits of electromagnetic heat. There are improved melting rates with uniform temperature distribution. There is also a drastic reduction in heat loss while also preventing overheating. Performance is also enhanced due to the coil winding techniques employed by these furnaces. All of these features ensure that the furnace will save on energy costs which are always a plus for any company.


An electromagnetic furnace for melting steel is very versatile. It has multiple power ratings and a large melting capacity range. The furnaces also come in different sizes. Smaller, compact designs are available that will require less work space and provide a more comfortable work environment for operators.


Furnaces for melting steel are also very durable. Older technologies do not last as long, and crucibles often have to be replaced through a shorter period of time. However, a steel furnace using induction and IGBT technology has a long crucible life. This will ensure that money is saved and profits are maximized. Additionally, maintenance of these furnaces is not difficult, so downtime is greatly reduced. This allows for more time to be spent manufacturing the steel and less time trying to fix the machine essential to the steel melting process.
