Posco has awarded a contract to Linde Gases for the installation of Rebox Direct Flame Impingement (DFI) technology

Linde’s DFI technology boosts production, as oxyfuel flames directly heat the moving metal, providing higher heat-transfer rates and resulting in increased capacity and reduced fuel consumption.
The installation will improve two of Posco’s continuous annealing lines at its steel mill in Pohang.
The unit’s small size allows easy retrofits.
The technology can also influence surface properties.
Linde’s Rebox DFI unit provides pre-heating that can achieve approximately 15 per-cent higher capacity in the annealing furnace.
The installation will increase Posco’s production capacity.
The natural-gas fired DFI unit will consist of four oxyfuel burner row units with a combined capacity of close to 6MW.
Compared with air-fuel systems, oxyfuel can boost production throughput by up to 50 per-cent, reduce fuel consumption and CO2 emissions by the same amount and reduce NOX output.
