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

steel research international, Volume 97, Issue 8, Page 4363-4381, August 2026.
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.

Clinker-Free Cement Manufactured with Metallurgical Slags

Buildings
Steel slag is a significant environmental liability generated by pyrometallurgical processes. Residue generation, such as granulated blast furnace slag and basic oxygen slag (BOF), is intrinsic in steel production.

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, Volume 97, Issue 8, Page 4126-4137, August 2026.
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 ...

Performance improvement of recycled aggregate concrete using fly ash and Portland blast-furnace slag cement

Journal of Materials and Engineering Structures, 2022
Several countermeasures are implemented in the manufacture of construction materials to avoid negative impacts on the environment. Using concrete debris in construction demolition waste as a recycled aggregate to make recycled aggregate concrete (RAC) is

Drying shrinkage of mortars with limestone filler and blast-furnace slag

Materiales de Construccion, 2003
During the 1990's the use of cements made with port land clinker and two mineral admixtures, called ternary or blended cements, has grown considerably. Nowadays, cements containing several combinations of fly ash and silica fume, blast-furnace slag and ...

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, Volume 97, Issue 8, Page 4138-4161, August 2026.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

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

steel research international, Volume 97, Issue 8, Page 4223-4233, August 2026.
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 (=
