Waelz slag is an iron-containing waste generated during electric arc furnace (EAF) dust processing in a rotary kiln named the process. This study focuses on reduction smelting of to produce iron-based alloy. The thermodynamic simulation using FactSage 8.0 software was carried out predict temperatures metal and obtained as well their compositions. Based results, experiments were performed labora...

Anaerobic digestion (AD) is a biological process in which organic wastes are converted into gases such as CH4, CO2, and H2S by microorganisms. In AD, using additives widespread approach to improve the anaerobic environment of microbial communities, increase microorganisms' activity, provide more biogas production. This study investigates effects adding electric arc furnace slag (EAFS) an additi...

This paper present the results obtained by simulation for the functioning regime improvement of an UHP Electric Arc Furnace. Because the nonlinearity of the electric arc the EAF functioning regime are perturbed from three causes: the current harmonics, the reactive power and the unbalanced load. In this paper there are study the possibilities of harmonics filtering and compensate the reactive p...

The electric arc furnace (EAF) is used to produce high quality steel from steel scraps. The EAF uses plasma arc to generate heat for melting scarp or direct reduced iron (DRI). The liquid metal should be drained from the tap hole. Manual tapping operation of the EAF in the hot environment around the furnace is a potentially dangerous and time consuming task for the workers. Therefore, it is ess...

electric arc furnaces (eafs) are unbalanced, nonlinear and time varying loads, which can cause many problems in the power system quality. in steel industries, the two arc furnaces often perform in parallel and stand on a single bus, which surely deteriorate the power quality. in this paper, in order to study and analyze the harmful effects of parallel operation of eafs, first, a three phase arc...

Temperature control is the primary concern during design and construction process of mass concrete structures. As production has an enormous negative environmental impact, development green concretes will eventually become as important thermal characteristics. Therefore, this paper investigates use Electric Arc Furnace (EAF) steel slag aggregate for partial replacement natural in concrete. The ...

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...
