What is continuous casting?

• A. It solidifies molten metal into billets, blooms, blanks, rounds or slabs
• B. It forms shapes from forging
• C. It coats molten metal with protective oxide
• D. It mills metal into sheets

Answer: (A)

Continuous casting means turning molten metal into solid shapes in one continuous process, producing billets, blooms, slabs, rounds, or similar forms. The metal is poured into a mold and pulled through as it solidifies, forming a long strand that is cooled and cut to length. This method is efficient and yields high-quality semi-finished products, avoiding the need to make a single ingot first and then further shape it.

The other options describe different operations—forging shapes metal by deformation, applying a protective oxide coating, or milling to create sheets—none of which involve continuously solidifying molten metal into long, ready-to-cut forms.
