This study investigated the possibility of using electric-arc furnace dust (EAFD) as an acidic soil amendment. The experiments were conducted using incubation and pot experiments. In the incubation experiment, various rates of EAFD were added to an acidic soil and properties such as pH; electrical conductivity of the saturation extract (ECse); and available phosphorus (P), potassium (K), iron (...
this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...
an electric arc furnace (eaf) is known as nonlinear and time variant load that causes power quality (pq) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. one of the most important problems to study the eaf behavior is the choice of a suitable model for this load. hence, in this paper, a probabilistic three-phase model is proposed base...
The rapid increase of non-linear loads in the last three decades has caused electrical quantities such as voltages and currents in 3-phase distribution systems to become distorted waveforms. This paper reviews, explains and discusses some new concepts, definitions and new available theory in the unbalanced and distorted systems. The usefulness of the proposed practical definitions is investigat...
This research studies the properties of mortars incorporating waste materials including red mud (RM), ground granulated blast furnace slag (GGBFS), and electric arc dust (EAFD). Ordinary Portland cement (OPC) was partially replaced with equal contents RM, GGBFS, EAFD at different ratios by weight (0, 5, 10, 15, 20, 30, 40, 50%). Slump, compressive strength, splitting tensile electrical resistiv...
Electric arc furnace slag (EAFS) and electric dust (EAFD) are the waste materials from steel production by EAF route which implies remelting of iron scrap in furnaces (EAF). In recent years, special attention is paid on valorisation EAFS EAFD since disposing both may cause negative impacts environment. this paper, methods that use to process have been reviewed, their advantages disadvantages al...
Microwave heating of waste electric arc furnace dust (EAFD) for the purpose its remediation has been studied extensively. However, these studies considered EAFD as a bulk material without addressing either relative response individual constituents or specific interactions with magnetic fields an electromagnetic wave. In this work, we present study contribution wave components to using separated...
The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system for control the harmonics filters, the reactive power compensation installation and the electrodes position, in order to obtain a high val...
In recent years many different ways have been investigated by steel producers to increase ductility, impact strength and formability of steels. More important ways are steels with very low amounts of inclusion, small size inclusions and modified inclusions. In this study, experiments have been performed on the API-X42 steel produced by the electric arc furnace in Mobarekeh Steel Co. After the p...
