What is Ductile Iron? - Willman Industries
Ductile Iron is a type of cast iron known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical (round) graphite structures in the metal. Ductile Iron is also called ductile cast iron, spheroidal graphite cast iron, or nodular cast iron.
Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.
Iron Ore Pelletizing Process: An Overview | IntechOpen
10/7/2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing …
