Where is cast iron manufactured/melted for foundry use? Select the most appropriate furnace commonly used to produce molten cast iron from pig iron and scrap for casting. Choose the correct option.

Difficulty: Easy

Blast furnace
Cupola
Open hearth furnace
Bessemer converter

Correct Answer: Cupola

Explanation:

ConceptPig iron is produced in a blast furnace. For foundry casting, pig iron (with scrap and fluxes) is remelted in a cupola to produce molten cast iron. Open hearth and Bessemer are steelmaking processes.

Final AnswerCupola
