Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Experimental and Numerical Investigation of Biocarbon Injection Behavior for Electric Arc Furnace Slag Foaming

steel research international, EarlyView.
Biocarbon injection is investigated as a promising pathway for sustainable electric arc furnace steelmaking using a combined experimental–numerical approach. Results demonstrate that biocarbon can effectively penetrate slag and generate intense foaming within a defined operating window.

Numerical Study of Argon Bubble Transport and Entrapment in Continuous Casting Using a Multiphase Approach

steel research international, EarlyView.
Bubble transport in continuous casting is controlled by the interaction of bubble size, flow dynamics, and operating conditions. Critical regions governing bubble escape and entrapment are identified, revealing the mechanisms responsible for defect formation and providing practical guidance for process optimization. Argon injection is often used in the

Effect of Hot Rolling Temperature on Oxide Scale Formation, Grain Size, and Pickling of Stainless Steel

steel research international, EarlyView.
The effects of finishing rolling temperature, coiling temperature, and annealing on scale formation and pickling performance are studied. Scale morphology and composition are studied via SEM‐EDS, and pickling performance is studied by evaluating scale residues and mass losses during pickling.
