The new converter supplements and reduces the workload of the existing vacuum oxygen decarburization (VOD) plant, allowing for shorter treatment times and improved product quality.
 
The planned capacity of the extended steel mill corresponds to an output of about 120,000 metric tons of stainless and special steel per year.
 
Primetals Technologies supplied the 50-ton AOD converter, the alloy and aggregate system, the doghouse and primary gas cooling system, auxiliary and ancillary equipment, as well as the electrical and automation systems. Installation of the converter required a custom solution due to the restricted height of the building.
 
BGH Freital operates an electric arc furnace and downstream secondary metallurgy unit, as well as an ingot caster and a horizontal continuous caster. A coarse ingot mill and a wire rod mill are used for further processing. Wire rods and bars 5–160 mm in diameter are produced from high-alloy materials as well as high-speed steel and nickel-based alloys.  
 
Primetals Technologies modernized the BGH Freital facility’s bar and wire rod mill drive and automation technology in 2013 and its electric arc furnace in 2017.
