Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

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 ...

Thermodynamics and Kinetics of Ammonia‐Based Reduction of Natural Hematite

steel research international, EarlyView.
Ammonia is investigated as a carbon‐free hydrogen carrier for reducing natural hematite into metallic iron. Higher temperature and smaller particle size promote faster reduction, while ammonia dissociation generates hydrogen that indirectly drives the reduction reaction. At 850 °C, high reduction degrees and porous metallic iron structures are achieved,

Coke Gasification - A Solution to Excess Coke Capacity and High Energy Costs

, 1982
United States crude slate is becoming heavier and generally higher in sulfur. At the same time demand of distillate products is increasing. Refiners are reworking their plans to include resid conversion via coking and approximately 230,000 BPD of new ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

High Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

‘Enthusiasts’ and ‘Fanatics’: The Decembrists as a Case Study in French Influence on Russian Culture, Emotions and Thought

History, EarlyView.
Abstract Participants in Russia's 1825 Decembrist uprising against the Tsarist regime were, quite literally, a case study in French cultural influence upon Russia. This is particularly true as it relates to Russia's emotional cultures. Although this has not, traditionally, been the primary focus of historical analysis of this event (in Soviet or ...

Statistical assessment of coal charge effect on metallurgical coke quality

Production Engineering Archives, 2016
The paper studies coke quality. Blast furnace technique has been interested in iron ore charge; meanwhile coke was not studied because, in previous conditions, it seemed to be good enough.
