· In induction furnaces large coils are wound around the crucible. AC current is applied, and this induces heat in the metal inside. Vacuum can be applied to the melt to increase purities of the final steel.
· Arcing furnaces use carbon electrodes at high potentials to create arcs. These act to heat the metal.
· The furnaces reach temperatures up to 3500°F.
