Steelmaking is the process for producing steel from iron ore and scrap In steelmaking, impurities such as nitrogen , silicon , phosphorus , sulfur and excess carbon are removed from the raw iron , and alloying elements such as manganese , nickel , chromium and ,
How Iron and Steel Work , The carbon combines with oxygen to create carbon dioxide and carbon monoxide (releasing lots of heat in the process) Carbon and carbon monoxide combine with the oxygen in the iron ore and carry it away, leaving iron metal , Wrought iron is hardy and easy to work, making it perfect for creating tools
The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke .
Iron was first made as wrought iron, a metal that could be shaped by hammering and bending to make many useful objects and components It was also capable of being modified by a number of techniques that could make it harder or tougher, both very useful properties for a number of tools and weapons
THE MAKING OF IRON AND STEEL 2 , The refining of iron to make steel is where the carbon content of hot metal is lowered, usually to , iron, or mixtures of scrap and other iron units Compared to the BOS process, the EAF requires less chemical reaction for refining
Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter The heat of oxidation raises the temperature and keeps the iron molten
The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota Creating steel from low-grade iron ore requires a long process of mining, crushing.
