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 ...

Isothermal Reduction Behavior and Microstructural Evolution of Iron Ore Sinter Under Simulated Radial Blast Furnace Gas Atmospheres With Hydrogen Injection

steel research international, EarlyView.
Commercial iron ore sinter is reduced isothermally under operation‐derived radial blast furnace gas atmospheres with and without 20 kg H2/tHM injection. Hydrogen improves reduction at 900–1100 °C, whereas at 700 °C the high H2O content limits the wüstite‐to‐iron driving force.

Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process

steel research international, EarlyView.
This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.

Fuel Indices for Estimation of Slagging of Phosphorus-Poor Biomass in Fixed Bed Combustion

, 2017
The market for solid biofuels will grow rapidly during the coming years and there will be a great demand for raw materials. This will force the existing fuel base to also cover wooden materials of lower qualities as well as agricultural raw materials and

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.

A Critical Review on Nitrogen Control in the Scrap‐Based Electric Arc Furnace Steelmaking Route to Produce Low‐Nitrogen Steels

steel research international, EarlyView.
In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...

Atomic‐Scale Insights Into Tramp Element Segregation and Mechanical Performance of a Low‐Carbon Steel

steel research international, EarlyView.
Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...
