Pig iron – IspatGuru

Apr 01 2013Merchant pig iron is basically of two types: Basic grade – Basic pig iron has less than 1 0 percent silicon under 1 percent manganese and trace amounts of sulphur and phosphorous This type of pig iron is mainly used for steel making There are several grades specified in various standards based on silicon and manganese content of the pig iron

The Ironmaking Process

The final product from the melter process is liquid iron which is tapped every four hours into refractory lined steel containers called ladles and transported to the steel plant where it is converted and refined into liquid steel The typical hot metal chemistry of the molten pig iron transferred to the steelmaking process is:

Differences Between Pig Iron and Carbon Steel

Pig iron is made when you melt charcoal iron and limestone together through intense air pressure After the melting process you can now derive the metal material pig iron Pig iron is a very high carbon product This raw product cannot be used the way it is since the end material is still unstable and very brittle To make use of pig iron

A Short History of Steel and the Bessemer Process

Blister steel—one of the earliest forms of steel—began production in Germany and England in the 17th century and was produced by increasing the carbon content in molten pig iron using a process known as cementation In this process bars of wrought iron were layered with powdered charcoal in stone boxes and heated
