Pengaruh Reagen Pelindian pada Sintesis ZnO dari Debu Tungku Busur Listrik

Jurnal Rekayasa Proses, 2020
ZnO nanoparticle was synthesized by a simple hydrometallurgical method using raw material of electric arc furnace dust (EAFD),which is a solid waste in the stainless steel industry. Electric arc furnace dust contains 68.81% Zn in the form of zincite (ZnO)

Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models

steel research international, EarlyView.
A in time and space discretized, thermodynamically sound model for direct reduction of iron oxide pellets is described. The number of fitting parameters is drastically reduced compared to existing models. Nevertheless, fitting kinetic parameters based on conversion degree data alone leads to overfitting, which can be mitigated by correlating the ...

Thermal stability and leaching behavior of alkali-activated slag doped with electric arc furnace dust [PDF]

Science of Sintering
The study presented in this paper explores the simultaneous valorization of electric arc furnace slag (EAFS) and electric arc furnace dust (EAFD) through an alkali activation process, as well as the thermal stability of the resulting product.

Dust formation in Electric Arc Furnace: Birth of the particles [PDF]

Powder Technology, 2005
The characterization of Electric Arc Furnace (EAF) dust shows that bubble burst at the liquid steel surface is the principal source of dust emission. We have therefore developed an experimental device for studying this phenomenon. As in the case of the air-water system, the bubble-burst gives birth to two types of droplets: film drops and jet drops ...

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

steel research international, EarlyView.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Comparative study of Cr, V and W recovery from a self-reduction briquette and a steel-briquette system

Journal of Materials Research and Technology, 2020
The objective of this study was to analyze the recycling possibility of the electric arc furnace dust (EAFD) in the form of a briquette. This paper studied the kinect behavior of the briquette's self-reduction and in contact with molten steel (steel ...

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.

Influence of Na2O/Al2O3 and SiO2/Al2O3 ratios on the immobilization of Pb from electric arc furnace into the fly ash based geopolymers

E3S Web of Conferences, 2013
Electric arc furnace dust (EAFD) is by-product of iron and steel scrap remelting in electric arc furnace. This waste is classified as a hazardous material due to the leaching of heavy metals into the environment.

Zinc and Strontium‐Doped Titania Nanotube Surfaces Enhance Antibacterial Activity and Increase Osteogenic Differentiation of Mesenchymal Stem Cells

Advanced NanoBiomed Research, Volume 6, Issue 3, March 2026.
Bacterial infection and poor integration often lead to orthopedic implant failure. Modifying implant surfaces can improve osseointegration. Titanium has been engineered to form titania nanotubes doped with zinc and strontium. These surfaces were evaluated for antibacterial effects and their ability to promote osteogenic differentiation in stem cells ...

Thermodynamic Modeling of Zinc Speciation in Electric Arc Furnace Dust

High Temperature Materials and Processes, 2011
The remelting of automobile scrap, containing galvanized steel, in an electric arc furnace (EAF) results in the generation of a dust, which contains considerable amounts of zinc and other metals. Typically, the amount of zinc is of significant commercial
