Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Double Slag Operating Standard for Mitigation of CO2 Emissions in Basic Oxygen Steelmaking

steel research international, EarlyView.
Basic oxygen furnace (BOF) steelmaking uses a double slag process (DSP) to produce low‐phosphorus steel. To reduce carbon emissions in a BOF, the hot metal ratio (HMR) must be lowered. The present article describes the optimal conditions for DSP operations under low‐HMR conditions: temperature of 1360 ± 5 °C, total Fe content of 10 ± 2 wt%, basicity (=

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.
