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 ...

This paper analyzes how feasible it is to use electric arc furnace slag as coarse aggregate, and blast furnace dust as fine aggregate in the manufacture of hot asphalt concrete for roads. Three mixtures were designed using the Ramcodes methodology, the M1 mixture of control with conventional materials, the M2 mixture replacing 50% and the M3 mixture replacing 100% of the conventional aggregates...

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...

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...
