Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

A Novel Approach to Energy Management in Electric Steelworks

steel research international, EarlyView.
Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

Decreasing the Environmental Impact of the Electric Steelmaking Route Through Advanced Modelling Techniques

steel research international, EarlyView.
Ensemble models are adopted to estimate the sterile content of scraps arriving to the scrap yard. Feed‐forward neural networks are exploited to estimate steel composition and temperature after Ladle furnace. The models are validated on data from two steelworks very satisfactory results and are inherently transferable to other steelworks, as they are ...

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 Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

steel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Characterization of Nonmetallic Inclusions in Ce‐Containing Steels at the Submicroscopic Level

steel research international, EarlyView.
Accurate detection of nonmetallic inclusions (NMIs) is crucial for ensuring high standards in steel cleanness and properties. Optimized automated SEM/EDS measurements are required for evaluating Ce‐containing NMIs. This study enhances the characterization of submicroscopic NMI in Ce‐alloyed ultralow‐carbon, high‐manganese, and electrical steels ...
