Structural ceramics containing electric arc furnace dust
Journal of Hazardous Materials, 2013In the present work the stabilization of electric arc furnace dust EAFD waste in structural clay ceramics was investigated. EAFD was collected over eleven production days. The collected waste was characterized for its chemical composition by Flame Atomic Absorption Spectroscopy.

Characterization of steel mill electric-arc furnace dust
Journal of Hazardous Materials, 2004In order to make a complete characterization of electric-arc furnace (EAF) dust, as hazardous industrial waste, and to solve its permanent disposal and/or recovery, bearing in mind both the volumes formed in the Croatian steel industry and experiences of developed industrial countries, a study of its properties was undertaken. For this purpose, samples

Removal of chloride from electric arc furnace dust
Journal of Hazardous Materials, 2011Electric arc furnace (EAF) dust with high chloride content increases the threat of dioxin emissions and the high chloride content reduces the value of recycled zinc oxide produced by EAF dust recycling plants. This study conducts a number of laboratory experiments to determine the technical feasibility of a new dechlorination method.

The flash reduction of electric arc furnace dusts
JOM, 1992The flash processing of electric arc furnace (EAF) dusts is a promising method for recovering zinc and producing nontoxic slags for direct disposal. In order to reduce the zinc content of the dust particles and maintain the iron content in oxide form, a certain range of temperature and oxygen potential must be provided, as dictated by thermodynamic ...

Study on Recycling of Electric Arc Furnace Dust
Materials Science Forum, 2014Electric arc furnace steelmakers are finding that dealing with the dust is increasingly difficult. Stockpiling this dust on site, recycling or sending offsite for disposal all entail considerable difficulties and costs. Succesful recycle of the valuable metals (iron, zinc) present in electric arc furnace dust will result in resource conservation while ...

Mineral phases of weathered and recent electric arc furnace dust
Journal of Hazardous Materials, 2008A weathered and a recent sample of electric arc furnace dust (EAFD), generated in a southern Brazilian steel industry, were characterized by X-ray fluorescence spectroscopy (XFA), powder X-ray diffraction (XRD), thermogravimetric analysis (TG), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) probe and Fourier transform ...

Glass-ceramic materials from electric arc furnace dust
Journal of Hazardous Materials, 2007Electric arc furnace dust (EAFD) was vitrified with SiO2, Na2CO3 and CaCO3 powders in an electric furnace at ambient atmosphere. Vitreous products were transformed into glass-ceramic materials by two-stage heat treatment, at temperatures determined by differential thermal analysis.

Characterization of directly sampled electric arc furnace dust
AIP Conference Proceedings, 1982As one part of a project to characterize electric arc furnace dust, direct sampling of particulates inside two furnaces has been undertaken. The sampled particles from two separate furnace runs were characterized by analytical electron microscopy. The elemental analyses were performed using energy dispersive x-ray analysis.

Characterization of Sintering Dust, Blast Furnace Dust and Carbon Steel Electric Arc Furnace Dust
2015In order to make a complete understanding of steel plant metallurgical dusts and to realize the goal of zero-waste, a study of their properties was undertaken. For these purposes, samples of two sintering dusts (SD), two blast furnace dusts (BFD), and one electric arc furnace dust (EAFD) taken from the regular production process were subjected to a ...

Recycling of electric arc furnace dust into glass-ceramic
Materials Chemistry and Physics, 2018Abstract Electric arc furnace dust was vitrified by SiO2, NaCO3 and CaO. The glass-ceramic produced from steel making dust was investigated in three aspects; stability of compounds, microscopic structure and mechanical properties. Leaching tests on electric arc furnace dust showed that the amount of Zn and Cd exceeded the environmental regulatory ...
