Influence of Hydrogen Fuel Mixtures on the Oxide Scale Formation of Low‐Carbon Steels in Reheating Furnace Conditions

open access: yessteel research international, EarlyView.
This work illustrates how substituting natural gas with hydrogen as fuel in the reheating furnace will influence the oxide scale formation on the steel surface. Thermogravimetric analysis and characterization techniques are used to investigate oxidation behavior and the formation of oxide phases.

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models

open access: yessteel research international, EarlyView.
A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...

Reduction, Softening, and Melting Characteristics of Mill Scale‐Based Briquettes for Blast Furnace Ironmaking

open access: yessteel research international, EarlyView.
The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

Metals' Adsorption Onto Environmental Microplastics at Shoreline Sediments

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT This study assessed trace element concentrations and microplastic (MP) contamination in three sandy beaches on the southern coast of Ilha Grande (Rio de Janeiro, Brazil). Environmental MPs were manually extracted from sand samples, and beaches were classified using the microplastic pollution index (MPPI).
