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.

Briquetting of Saw Dust

, 2011
Briquettes produced from agro-residues are fairly good substitute for coal, lignite and firewood. Briquettes from saw dust have high specific density of 1400 kg/m3 compared to bulk density of 210 kg/m3 (approx.) of loose saw dust.

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 ...

OPTIMAL DESIGN AND EVALUATION OF A RING-DIE GRANULATOR FOR STRAWS

BioResources, 2011
This research provides an optimal design of structural parameters for ring-die granulators used in the cool briquetting process. Experimental research on the briquetting rate of pellets was carried out for three kinds of crop straws with different ...

Hydrogen Reduction of Synthetic Fe2O3 Pellets: The Role of Calcium Oxide in Porosity Evolution and Reduction Kinetics

steel research international, EarlyView.
At 800 °C, hematite pellets containing 0.9 wt% CaO reduce in hydrogen at rates 1.2–1.4 times those of pure pellets. The inward‐moving reaction front supports a topochemical description, and FeO‐to‐Fe kinetics are consistent with mixed control by interfacial reaction and intrapellet diffusion.

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 ...
