Decarbonization of Mold Flux: Contributing to Carbon Footprint Reduction

Room: A212 - 03:30 PM - 04:00 PM 


Author(s): 

José Augusto Cardoso Ferreira, HWI, A member of Calderys
Jeferson Klug, Federal University of Ceará

The presentation explores innovative mold flux decarbonization initiatives - from production to application in steel casting - to reduce carbon emissions and fossil fuel consumption. Traditionally, mold flux contributes to high carbon output. Reduction of this content can also result in better quality, less product deviation, and increased yields in operation. These advancements enable steelmakers to align with global sustainability goals and support a transition to more eco-friendly practices without sacrificing performance. The scalable solutions presented suggest the potential for even more significant reductions in carbon emissions.

Reduction of Corrosion of Tundish Stopper Rod Caused by Covering Powder 
Room: A212 - 09:00 AM - 09:30 AM 

Author(s): 

José Augusto Cardoso Ferreira, HWI, a member of Calderys
Edson Maranhão, HWI, a member of Calderys
Thaísa F. Silva, Ternium Brasil
Giovani Apolinário, Ternium Brasil
Wagner Bielefeldt, Federal University of Rio Grande do Sul
Jeferson Klug, Federal University of Ceará

The team will present innovative solutions utilizing Ca-aluminate tundish covering powders that extend refractory durability and improve steel product quality while promoting operational energy efficiencies and safety. The research applied computational thermodynamics to devise a covering powder composition that significantly mitigates stopper rod corrosion. This advancement extends the operational lifespan of the tundish from five to 12 heats, reducing steelmakers’ refractory consumption, energy demands, and carbon footprint. Optimized slag basicity also improves steel purity by minimizing non-metallic inclusions, thus lowering the risk of breakout accidents. The easy-to-implement solution can help redefine industry benchmarks and further support environmental sustainability. 


In addition to HWI’s technical session participation at the conference, Mary Lucarino, Application Specialist III, Integrated - Steel at HWI, a member of Calderys, will be featured in a chapter of the new book, More Women of Steel, Women in Steel Volume II, which will be released at AISTech 2024. 


As the industry looks to more automated solutions to ensure efficiency, energy savings, and safety, HWI and Calderys Group continue to lead the way with innovative approaches and technologies.
