Steelmaking is traditionally conducted using one vessel (the converter), but has recently been developed to include a hot metal dephosphorization process followed by a decar-burization process. In most cases, these two processes are separately conducted

In steelmaking, blast furnaces convert iron ore into crude iron by the reducing action of carbon at high temperatures. This crude iron or ‘pig iron’ still contains a lot of carbon and other impurities that need to be removed, partially or totally, by a reaction with oxygen.

IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. 58, NO. 8, AUGUST 2009 2611 A Sparse Robust Model for a Linz–Donawitz Steel Converter József Valyon and Gábor Horváth, Senior Meer, IEEE Abstract—Steelmaking with a Linz–Donawitz converter is a
Steelmaking slag consists of converter slag that is generated by converter and electric arc furnace slag that is generated during the electric arc furnace steelmaking process that uses steel-scrap as the raw material. Converter slag In the same way as air-cooled
Now let''s look at sequence of the steelmaking processes. The hot metal was well treated to remove sulfur, silicon, and phosphorus this will be decarbonized. This is supposed to be put into converter but before hot metal is charged it into converter, we use the
Slag carry-over from the steelmaking vessel into the ladle has a distinct effect on ferroalloy consumption. As in the case of LD converter, open hearth or EDF the steclmaking slag with 18 to 25%n iron dissolved in it as oxides, is intensely oxidising in nature
LD 2 Steelmaking Shop (LD2) came into operation in the year 1993(under Modernization Phase III – 1990-94) with production capacity of 1.3 MTPA. The shop initially had two converters of capacity 130 tonnes each; one more converter was added later on.

Das Linz-Donawitz-Verfahren (LD-Verfahren; englisch basic oxygen process, BOP) ist ein Sauerstoffblasverfahren zum Frischen, also zur Stahlerzeugung durch Umwandlung von kohlenstoffreichem Roheisen in kohlenstoffarmen Stahl. Mit dem LD-Verfahren werden derzeit 72 % der Weltrohstahlproduktion hergestellt (Stand: 2013).[1] Stahlwerke nach diesem

The Linz–Donawitz (LD) converter steelmaking process was patented in Austria in the early 1950s. The invention of the LD converter enabled the refinement of hot metal to crude steel in short blowing periods of around 20 min, enabling the high productivity of the

The primary steelmaking equipment is called the basic oxygen furnace (BOF) also known as Linz–Donawitz (LD) or oxygen converter (as shown in Figure1). Theoretically, converter steelmaking is a complex process including melting, purifying, and alloying which
