How pig iron is produced?
Regulation of Carbon.
(1) Electric Reduction Furnace: This type of furnace can be adopted at places where electric power can be economically and cheaply generated. There are various forms of this furnace. (2) Low Shaft Blast Furnace: In this furnace, the blast is made rich in oxygen.
The undesirable elements in the melt are diluted that aids in the depleted cost of scrap. The predictable and stable composition of the iron helps achieve better control over the final composition of casting, which leads to an enhanced mechanical output of the casting. It demands lower storage space and lesser charge buckets., and more items.
What is the difference between pig iron and cast iron?
The difference between pig iron and cast iron. Steelmaking pig iron The silicon content of steel-making pig iron is not more than 1.7%, and the carbon exists in the form of Fe3C. Cast iron The silicon content of cast iron is 1.25~3.6%. Carbon mostly exists in the state of graphite. Pig iron for ductile casting.
