Today, the 350-ton range is seen in several installations, and oxygen steelmaking has become the leading refining process in the world.

8th European Oxygen Steelmaking Conference

The European Oxygen Steelmaking Conference (EOSC) series is organised in turn by one of the European Metallurgical Societies and Associations. As such it represents the most comprehensive expert knowledge in steelmaking. After 21 years, the Conference will be organized once again in Italy in Apulia.

Basic oxygen steelmaking - Wikipedia

2019-4-24 · Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
