Is there any difference between the composition of pig iron and steel?
Iron in addition to iron, but also contains carbon, silicon, manganese, phosphorus and sulfur and other elements.The main difference between steel and steel is the difference in carbon content, as well as the resulting hardness and ductility differences.Generally less than 0.2% carbon content that wrought iron or iron, the content of 0.2-1.7% in the steel, is iron content of more than 2%. The carbon content of pig iron is usually between 2% and 4%.Pure iron is soft, plastic, good, easy to deformation, low strength and hardness, use is not wide; pig iron contains a lot of carbon, hard and brittle, almost no plastic. The use of steel is widely used in the manufacture of castings, and the plasticity of steel is very strong.
Iron cast iron wrought iron division refers to: wrought iron through a variety of after heating their carbon content decreases, the hardness increases.The difference between iron and wrought iron is how much of its carbon content. Cast iron with high carbon content, low carbon iron. Between the carbon content of steel between iron and wrought iron.
Crude iron produced directly from the blast furnace, can be further refined into wrought iron or steel, iron, or re melting and casting into a special shape. Carbon steel-making pig iron mainly exists in the form of iron carbide, the white section, usually called white iron. This kind of hard and brittle properties of cast iron is generally used to do in addition to iron steelmaking raw materials...
