The manufacturing process of cast iron is how the metal gets its name. To make cast iron, iron ore is heated in a furnace until it becomes molten. Then the molten metal is cast (poured out and allowed to harden, in the shape of an ingot). The cast iron ingots are melted again into a final mold. During this subsequent remelting, the cast iron ...
