How much electricity does an induction furnace use?
A modern coreless induction furnace can melt a tonne of iron and raise the temperature of the liquid metal to 1450 °C using less than 600 kWh of electricity. Typically, specific energy consumption of coreless induction furnace varies from 500 to 800 kWh per tonne depending on type and grade of casting.
How efficient is an induction furnace?
In a typical induction furnace the energy loss in equipment is between 100 to 130 kWh per tonne. The furnace efficiency is around 65 to 75%.
Can you melt copper in an induction furnace?
Induction equipment can melt/heat virtually all metals and materials including, gray and ductile iron, steel, copper and copper-based alloys, aluminum, zinc, reactive metals, precious metals, silicon and graphite.
What is the disadvantage of induction furnace?
Cost of the equipment and the cost of the process are very high. Efficiency of heating is poor being less than 50% in many cases. Heating will be more in regions of the work piece closer to heating coil.
What are the advantages of induction furnace?
Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel, copper, aluminum, and precious metals. The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting.
How do you increase the efficiency of an induction furnace?
Save power with maintenance Close attention to normal maintenance procedures can produce surprising energy savings at minimal additional cost. Keep a lid on it — About 75% of the heat loss in an induction furnace when the lid is open is in the form of radiated losses into the air from the surface of the molten bath.
How does induction furnace work?
In the induction furnace, a coil carrying alternating electric current surrounds the container or chamber of metal. Eddy currents are induced in the metal (charge), the circulation of these currents producing extremely high temperatures for melting the metals and for making alloys of exact composition.
Is induction heating economical?
Heating by Induction has minimal wasted heat, with direct transfer of energy to the part being heated. This high efficiency results in significant power savings. Induction heating proves to be a highly efficient method for industrial heating applications.
How do I choose an induction furnace?
Here are 10 factors to consider when selecting an induction heating system.
- Your Part’s Material. Induction directly heats conductive materials such as metals.
- Depth of Heating Penetration.
- Operating Frequency.
- Applied Power.
- Rise in Temperature Required.
- Coil Design.
- Coupling Efficiency.
- Your Facility and the Footprint.
Can an induction furnace melt steel?

What is an induction furnace used for?
The coreless induction furnace is commonly used to melt all grades of steels and irons as well as many non-ferrous alloys. The furnace is ideal for remelting and alloying because of the high degree of control over temperature and chemistry while the induction current provides good circulation of the melt.
