Conventional steelmaking begins by melting steel in a large electric arc furnace. The initial melting of the ... steel is usually followed by a secondary ladle refining process such as Argon Oxygen Decarburization (AOD) or Vacuum Oxygen Decarburization (VOD). ... Conventional Steelmaking vs. Powder Metallurgy Steelmaking. Powder Metallurgy ...
166 steelmaking define it as the refining – remelting process followed by the molten steel treatment in ladle furnace. This process produces slag with only small variations in composition and properties.

The applied mathematical description of the processes occurring in the ladle furnace enables the process simulation to be carried out in real time. The constructed model has been verified in industrial conditions for a ladle furnace of 140 t capacity.
Figure 9: Maximum steel velocities in the ladle as a function of ladle age and stirring intensity. The plot shows that in the oldest ladle are the velocities almost twice as high than the velocities in a new ladle. This probably leads to a higher erosion of the ladle wall resulting in more inclusions in the steel.

Solid alumina inclusions form in aluminum deoxidized steel in the ladle furnace. These solid inclusions are known to create challenges during casting in terms of nozzle clogging. In spite of various practices which are used for elimination of theses inclusions, some of them remain in the steel melt.
Sulfur refining (desulfurization) in the ladle metallurgy is performed by addition of fluxes (CaO, CaF. 2 and others) into the ladle and stirring the steel together with the slag, absorbing sulfur. In the production of high quality steel the operation of vacuum treatment in ladle is widely used.
Primetals Technologies will design a dedusting system to clean the offgases from the ladle metallurgy facility. This will process around 206,000 standard cubic meters per hour, and reduce the dust content of the cleaned gas to less than twelve milligrams per standard cubic meter.
The size and shape of the ladle, the location of the porous plug, the location of the ferroalloy addition, and the sampling location are illustrated in Figure 1. Heat 1 was the twentyfirst heat of the ladle refractory campaign and the sixth heat on the alumina porous plug.

Ladle Furnace (LF) Molten steel treated in Ladle Furnace is covered by a layer of desulfurizing slag. The graphite electrodes are submerged into the slag, which protects the ladle lining from overheating produced by the electric arcs. The arcs are capable to heat the steel at the rate about 5°F/min (3°C/min).

Ladle Arc Furnace 3D interactive model The operation executed at the ladle furnace is an essential part of the secondary metallurgy treatment, such as refining, adjustment of liquid steel temperature and chemical composition with the target to increase quality of steel.
Keywords: ingots, casting ladle, mould, casting pit 1. INTRODUCTION Casting is a final metallurgical operation in steel metallurgy. After the melting in primary furnace (BOF, EAF), steel is tapped in steel ladle, treated on secondary furnace (ladle furnace) and finally sent for ingot casting.
Ladle Metallurgy. After tapping of steel from a primary steelmaking furnace such as BOF, EAF or EOF, molten steel for high quality or specialty applications is subjected to further refining in a number of alternative processes collectively known as ladle metallurgy.
