this research was conducted in order to evaluate fatigue behavior of asphalt mixes containing electric arc furnace (eaf) steel slag. after initial evaluation of the properties of eaf steel slag using x-ray diffraction (xrd) and scanning electric microscope (sem), six sets of laboratory mixtures were prepared. each set were treated replacing various portions of limestone aggregates of the mix wi...

Bottom-blowing, as widely adopted in electric arc furnace (EAF) steelmaking technology, stir the molten bath by blowing inert gas (Ar, N2) from the bottom of EAF to promote fluid flow and uneven metallurgical reaction in the molten bath. However, for eccentric structure design of electric arc furnace, the problem still exists in EBT(Eccentric Bottom Tapping)area. In this study, by the analysis ...

A 2D axisymmetric two-phase model was developed to study the effect of an arc impingement on liquid metal inside electric furnace. In addition flow dynamics, covered heat transfer and magneto hydrodynamics metal. Through a parametric study, three different parameters were considered predict most important factors affecting overall behaviour process: gap, density gas, total current. Understandin...

The energy used to produce austenitic stainless steel was quantified throughout its entire life cycle for three scenarios: (1) current global operations, (2) 100% recycling, and (3) use of only virgin materials. Data are representative of global average operations in the early 2000s. The primary energy requirements to produce 1 metric ton of austenitic stainless steel (with assumed metals conce...

Abstract Effective recycling of zinc-containing industrial wastes, most importantly electric arc furnace dust, is tremendous importance for the circular economy steel and zinc industry. Herein, we propose a comprehensive kinetic model combined carbothermic metallothermic reduction oxide in metal bath process. Pyro-metallurgical, large-scale lab experiments carbon-saturated iron melt as agent mo...

While the sources of releasing dioxins have received much attention, the health risks of incinerators are studied considerably more than those of other sources, such as metallurgical industry. Furthermore, risk assessments focus primarily on the effects of single sources; few have addressed the aggregate risks from multiple sources in a region. When many sources of dioxins exist in an area, suc...

The revalorization of solid wastes and by-products to be applied as particles in concentrated solar power (CSP) leads cost savings progresses toward more sustainable technology. Herein, the physicochemical, morphological, thermal, absorption properties are evaluated for electric arc furnace dust, black slag from steel industry, Gossan waste Rio Tinto mining industry. principal objectives this w...

The electric Arc Furnace Dust (EAFD) sample leaching using two different organic carboxylic anions has been previously studied, as a separate article. aim of the present research work (Part II) is study on kinetics EAFD, comparing efficiency sodium citrate with that sulfuric acid solutions. effect solid / liquid ratio, temperature and reagent concentration in solutions metallic dissolution was ...
