Steelmaking (EAF)
Melting scrap steel at 1600°C in Electric Arc Furnace (EAF), chemical analysis and refining in ladle furnace.
The steelmaking plant is the first and most critical stage of the steel production chain. Using Electric Arc Furnace (EAF) technology, selected scrap steel is melted above 1600°C to produce liquid steel. During this process, arc energy is used to remove all impurities from the scrap and achieve the desired chemical composition.
In the Ladle Furnace (LF) stage, the chemical composition of liquid steel is precisely adjusted. Desulfurization, deoxidation, and addition of alloying elements are carried out at this stage. Thanks to computer-controlled systems, each charge is analyzed with ±0.01% precision.
The Vacuum Degassing (VD) unit removes harmful gases such as hydrogen, nitrogen, and oxygen from liquid steel. This process is critically important, especially in the production of high-quality special steels. In a vacuum environment (0.5–1 mbar), gas levels are reduced to minimum.
The VODC unit is particularly used in the production of stainless and high-alloy steels. By blowing oxygen under vacuum, carbon levels are reduced while chromium loss is minimized. The entire process is monitored and recorded by CNC-controlled systems.
