AOD
Argon Oxygen Decarburization (AOD) is used during the refining process to produce steel with low carbon properties and low silicon levels, while creating a metal more weldable and more corrosion and heat resistant. It brings the tightest chemistry control to deliver the highest levels of metal purity.
The process injects oxygen and inert gas (argon or nitrogen) through submerged tuyeres and additional oxygen is blown through a top lance. The AOD process is suitable for production of stainless steel and other high-grade alloys because dilution with argon/nitrogen minimizes unwanted chromium oxidation.
Efficiency
- Efficient operation even with high initial carbon levels
- Use of less expensive high-carbon alloys
- Low chromium oxidation losses
- High rate of chromium recovery with proper additions
- Chemical heating of liquid steel
- Low final dissolved gas content

Secondary Metallurgy
The increasing demand for high-quality steel makes the secondary metallurgy to an essential step in metallurgy process. The handling of alloys, degassing and desulfurization technologies as well as high-efficient decarburization solutions are representing an indispensable part of the production of high-quality steel.
RH / RH-OB
The Ruhrstahl Heraeus (RH) vacuum recirculation process is carried out in a refractory-lined vessel equipped with two snorkels immersed in the steel bath. The process is focused on decarburization and degassing and is the best suitable system for the production of Ultra Low Carbon Steel grades.
Twin / Single LF and Treatment Stations
Tenova Ladle Furnaces enable precise control of the melt temperature and of the chemical composition to guarantee improvement of productivity, flexibility and quality.
VD / VOD
The increasing demand for high quality steel makes the vacuum treatment an essential step in secondary metallurgy process. Tenova Vacuum Degasser units (VD) feature effective removal of hydrogen, oxygen and/or carbon, based on proven technology and experience
