Reducing Longitudinal Depression and Hot Cracking in Duplex Stainless Steel Slabs
Key Takeaways Problem: A stainless steel producer in Asia faced defects in duplex stainless steel slabs due to improper casting parameters and powder formulations. Challenge: Defects led to material loss, reducing yield and disrupting downstream operations. Solution: Identified defect causes, optimised casting settings and powder formulations, and provided staff training. Improvements: Reduced grinding loss to […]
Blast Furnace to EAF Transition: Navigating Challenges and Market Gaps
Main Takeaways The steel industry is shifting from traditional blast furnace (BF) methods to electric arc furnace (EAF) production to reduce carbon emissions and meet increasing demand, with EAF’s share of global steel production expected to rise from 28% to 41% by 2030. This transition is particularly notable in North America and Europe. EAFs require […]
