Which statement about oxygen in an electric arc furnace process is correct?

• A. Oxygen is required for refining
• B. Oxygen is not required
• C. Nitrogen is required
• D. Argon is required

Answer: (B)

In an electric arc furnace, melting and refining are achieved mainly through electrical energy, not by oxidizing with oxygen. The bath is refined through slag chemistry, fluxes, and controlled alloying, so oxygen isn’t a required part of the process. While inert or shielding gases like argon or nitrogen may be used in some specialized steps, they aren’t mandatory for the basic EAF operation.
