FINEX (steelmaking process) FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO. Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke.
Basic oxygen steelmaking ( BOS, BOP, BOF, or OSM ), also known as Linz-Donawitz steelmaking or the oxygen converter process, [ 1] 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.
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...
"The world needs low-carbon steel to reach net zero, and we are working to make this a reality by finding better ways to turn our Pilbara ores into steel," said Simon Rio Tinto Invests $143M in ...
Chris Isidore, CNN. December 18, 2023 at 7:49 PM. U.S. Steel. US Steel has agreed to be bought by Nippon Steel, Japan’s largest steelmaker, in a $14.1 billion deal. The deal marks the latest ...
Bessemer process. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature ...
In a recent 50/50 joint venture, ArcelorMittal and Nippon Steel and Sumitomo Metal bought the ThyssenKrupp AG Calvert, Alabama steel complex for $1.55 billion. The plant has a running capacity of ...
Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
