Q: 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.

Concept Pig 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 Answer Cupola
