The pig iron itself does not have much use but it finds a great number of applications when converted into steel alloys in the steel industry. The process of manufacturing pig iron is a bit complicated. The following steps explain the same as simply as possible. Raw Materials The raw materials used in the blast furnace to produce high quality pig iron are iron ore, coke, limestone, and sinter. Now, these iron ores are nothing but oxides of iron that contains other materials like limonite ...
How is cast iron made? 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 . The cast iron ingots are melted again into a final mold.
The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows
