Steel Making | Steel Plants | Business POSCO E&C

Steel Making Process - The process of making steel by removing the impurities from hot metal. Hot metal produced from a blast furnace is high in carbon and contains impurities such as phosphorous and sulfur. To prevent red shortness, however, it is necessary to remove sulfur from this hot metal through the KR (Kanvara Reactor).

RH Degasser (RH) | NIPPON STEEL ENGINEERING

2019-3-25 · RH degasser is a secondary refining system that removes dissolved gases such as hydrogen present in molten steel to enable the production of high-grade steel. Processes that remove the dissolved gases present in molten steel are necessary for the production of high-grade steel.

What is the difference between a primary steel and a

Well, Let Share Something Interesting. Steel-making is the process for producing steel from iron ore and scrap. In steel-making, 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 vanadium are added to produce different grades of steel.

Emerging Technologies for Iron and Steelmaking

The continued expansion of EAF steelmaking for the production of higher quality steel products is projected to continue. 10 However, this expansion will require continued technological development of the basic process of electric furnace steel-making. More than 40% of steel produced in the United States is produced by EAF, and that figure is

Vacuum Degassing of Steel - Vacaero

2019-4-27 · Vacuum degassing is a boundary layer phenomenon that occurs at the interface between the molten steel and the reduced-pressure atmosphere. Effective vacuum degassing depends upon sufficient exposed surface area of the molten steel. Vacuum degassing systems employ different methods to maximize this surface area.

Ladle refining [SubsTech]

Oxidation of liquid steel components under vacuum differs from that at normal pressure: oxygen is consumed mainly by the reaction [C] + [O] = {CO} rather than by oxidation of chromium, which is the main constituent of stainless steels. VOD process allows to decarburize the steel with minor chromium losses.

Vacuum Degassing Processes for Liquid Steel. During the primary steelmaking process, gases like oxygen (O2), hydrogen (H2) and nitrogen (N2) dissolve in the liquid steel. These gases have a harmful effect on the mechanical and physical properties of steel.

Basic oxygen steelmaking - Wikipedia

2019-4-26 · 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.
