FAQ
Frequently Asked Questions
No. An arc furnace uses a high-current electric arc for heating, while an induction furnace uses electromagnetic induction to generate heat within the metal itself.
Its primary advantage is the ability to melt scrap metal efficiently and produce high-quality steel or alloys with precise temperature control.
The steelmaking industry is the largest user, followed by foundries and plants producing ferroalloys like ferromanganese and ferrosilicon.
Yes, since it uses electricity, it can potentially be powered by renewable sources, making 'green steel' production a growing area of research and development.
