Basic oxygen steelmaking (BOS, BOF, Linz-Donawitz-Verfahren, LD-converter) is a method of steelmaking in which carbon-rich molten iron is made into steel.The process is an improvement over the historically important Bessemer process.The LD-converter is named after the Austrian placenames Linz and Donawitz (a district of Leoben).
more modern "basic oxygen steelmaking" (BOS) and "electric arc furnace" (EAF) processes. The BOS process uses pure oxygen, injected by a lance, for refining the relatively impure hot metal (and scrap is used for temperature control). The electric arc furnace uses primarily electrical energy to supply heat to melt scrap steel, sponge
Description Estimated time: 0.50 hours The purpose of the Basic Oxygen Steelmaking (BOS) process is to refine the hot metal produced in the blast furnace into raw liquid steel, which may be subsequently refined in the secondary steelmaking shop. The main functions of the Basic Oxygen Furnace (BOF) are to decarburise and remove phosphorus from…
Basic oxygen steelmaking. More than half the world''s steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at supersonic velocity ...
A recent study carried out by Urban et al. [1] from more than 30 basic oxygen furnace (BOF) plants around the world shows that phosphorus partition ratio is dependent on oxygen steelmaking blowing ...
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...

· Chemistry of Steelmaking by Basic Oxygen Furnace. During the steelmaking process by basic oxygen furnace (BOF), impurities in hot metal such as carbon (C), Silicon (Si), manganese (Mn), phosphorus (P) etc. are removed by oxidation for the production of liquid steel. Oxidation is carried out with high purity oxygen gas which is blown in the BOF.

Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace. The resulting molten iron - also referred to as ''hot metal'' - still ...
