Ratio Of Pig Iron Converted To Steel

How to Convert Pig Iron Into Steel | eHow

Pig iron is the basic building block of all ferrous metals. It is formed when iron ore is refined in a furnace in the presence of charcoal, limestone and air. It is the basic form of iron used to make decorative wrought iron items. When the pig iron is further refined and a minimum amount of carbon is added, the crystalline structure of the metal changes and steel is produced. Though possible to create at home, the majority …

How is Steel Produced? | World Coal Association

Steel is an alloy based primarily on iron. As iron occurs only as iron oxides in the earth’s crust, the ores must be converted, or ‘reduced’, using carbon. The primary source of this carbon is coking coal.

Pig iron - Wikipedia

Pig iron is an intermediate product of the iron industry, also known as crude iron, which is first obtained from a smelting furnace in the form of oblong blocks. Pig iron has a very high carbon content, typically 3.8–4.7%, [1] along with silica and other constituents of dross , which makes it very brittle and not useful directly as a material except for limited applications.

Iron and steel - Introduction to their science, properties ...

Pig iron is actually a very basic form of cast iron, but it's molded only very crudely because it's typically melted down to make steel. The high carbon content of cast iron (the same as pig iron—roughly 3–4 percent) makes it extremely hard and brittle: large crystals of carbon embedded in cast iron stop the crystals of iron from moving about. Cast iron has two big drawbacks: first ...

Difference between Iron and Steel | Iron vs Steel

Iron is more commonly found in alloy forms such as steel alloys, crude iron, wrought iron and pig iron. These alloys are significantly strengthened and hardened because of the impurities such as carbon.
