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.

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 ...

Evolution of the strength characteristics of briquette and raw coal containing fluid
Scientific Reports, 2023 The mechanical properties of coal containing fluid are an important factor affecting the safe mining of soft coal seams. In particular, for class III–V coal, coal and gas outbursts and other dynamic phenomena are prone to occur due to the influences of ...

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.

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,

The Scholar Imprisoned: Young‐Bok Shin's Decolonial Thought Against (Sub) Imperialisms in East Asia
Sociological Forum, EarlyView.ABSTRACT This article reads Young‐Bok Shin (1941–2016) as a decolonial thinker who theorized transformative worldmaking from the standpoint of the oppressed, rooted in the historical experiences of East Asia. Against the (sub)imperial “logic of sameness” that structures colonial modernity in his social world, Shin advances gongbu (studying) as a ...
