Effect of Flow Rate and Partial Pressure of Oxygen on Desulfurization of KR Slag
MetalsKR (Kanbara Reaction) desulfurization slag is a solid waste that is not sufficiently utilized. This is because the KR desulfurization slag contains 1–2.5% sulfur, which is directly used in steel smelting to increase the sulfur content in molten steel ...

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking
steel research international, EarlyView.This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
steel research international, EarlyView.This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

steel 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 ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
steel research international, EarlyView.Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in
