Steps in the Modern Steelmaking Process

Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.

Pig Iron Manufacturing Process

The combustion processes which have attempted to produce a product which might be classified as a pig steel rather than pig iron, have failed largely for economic reasons rather than because of metallurgical difficulties. They were not adapted to the large units necessary to turn out a large tonnage, as is the case in the manufacture of pig iron.

Creating Steel | HowStuffWorks

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. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
