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 […]
Optimising EAF Chromium oxide recovery and Oxygen Consumption for Duplex and Ferritic Stainless Steels
Key Takeaways Here are five key takeaways from this document: Problem: A client in Asia faced high oxygen and aluminium consumption in a 140-tonne EAF, leading to chromium losses in slag. Challenge: High operating costs due to inefficient raw material use and chromium losses. Solution: Reviewed and optimised EAF processes, including oxygen injection, charge mix, […]
Optimising AOD Chemical Composition of Duplex Stainless Steel
Key Takeaways Problem: A stainless steel producer in Southeast Asia faced quality issues due to non-optimised chemical compositions, leading to frequent casting defects. Challenge: Needed to optimise chemical composition to ensure consistent product quality. Solution: Adjusted desulphurisation and decarburisation steps and proposed SOP modifications for better chemical control. Improvements: Reduced steel sulphur content, controlled hydrogen […]
Operational excellence program at an Eastern European steel plant: Increasing yield by 15% with less than 1 million USD of capital expenditure
Key Takeaways Here are five key takeaways from this document: Problem: An Eastern European steel plant was underperforming, with low yield, high energy use, and inefficient scrap management. Budget for capital investments was very limited. Challenge: Key issues included long tap-to-tap times, outdated practices, and energy consumption far above benchmarks. Scrap operations and burner performance […]
