(a) Cupola

(b) Electric arc

(c) Induction

(d) Blast

I had been asked this question at a job interview.

I want to ask this question from Electric Arc Furnace topic in section Melting Furnaces of Foundry and Forging

Answer 1

Right choice is (c) Induction

To elaborate: The induction furnace is commonly used to melt all grades of steels and iron as well as many non-ferrous alloys. As it can be used for re-melting of the metals, it is suitable for melting of scrap and reusing it.
