Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

A Novel Approach to Energy Management in Electric Steelworks

steel research international, EarlyView.
Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

steel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

Briquettes manufacturing: mechanisation of briquette productions at SME santan coco

ABDIMAS TALENTA: Jurnal Pengabdian Kepada Masyarakat, 2019
The fabrication of briquettes is required to be introduced extensively to society in order to provide additional economic value for charcoal crafters to increase their income. The SME Santan Coco as partnership enterprise of community service under supervising of Universitas Sumatera Utara has been producing briquettes since 2018 resulted from waste of

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

TROPICAL FRENCH THEORY: Henri Lefebvre and the Reinvention of Urban Planning in Havana, Cuba (1968–1971)

International Journal of Urban and Regional Research, EarlyView.
Abstract Contributing to global urban history, planning theory and the geography of ideas, this article discusses the travels of Henri Lefebvre’s The Right to the City in the wake of May 1968, in France. That year, under the direction of Mario González and Max Baquero, a small team including the Italian architect Vittorio Garatti, French planner Jean ...

Preparation of sludge grinders for metallurgical remelting

Технічна інженерія, 2019
Waste of the metalworking industry is analyzed from the point of view of their further processing. There is a lack of effective methods of processing and disposal of grinding sludge and, as a consequence, a negative impact on the environment. Existing

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology

International Journal of Urban and Regional Research, EarlyView.
Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

Performance Evaluation of the Physical and Combustion Properties of Briquettes Produced from Agro-Wastes and Wood Residues

Recycling, 2018
This study investigated the physical and combustion properties of briquettes produced from agricultural wastes (groundnut shells and corn cobs), wood residues (Anogeissus leiocarpus), and mixture of the particles at 15%, 20%, and 25% starch levels ...

Economic Dependencies and Nationalist Divergences: Public Versus Private Sector Employment and Beyond in Corsican Separatist Nationalism

Nations and Nationalism, EarlyView.
ABSTRACT Separatist nationalism often persists in divided minority regions where internal factions struggle to agree on governance models, perpetuating conflict and political tension. This article examines the key structural and situational factors driving these divisions in Corsica, focusing on economic dependencies that shape divergent approaches to ...
