Accurate modelling of the Electric arc furnace (EAF) is necessary to study its impact on power systems. Here, a new model for EAF presented in which both non-linearity and time-varying characteristics are taken into account. The consists seven parallel current sources represent fundamental harmonic currents. Magnitude phase magnitude second seventh harmonics considered as updated every 0.01 s. ...

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...

A pulsed arc heater was designed and manufactured at Centrospazio to equip a new hypersonic high-enthalpy blow-down wind tunnel capable of producing flows with a specific total enthalpy up to 2.5 MJ/kg. The heater mainly consists of two coaxial electrodes, separated by a constrictor, and a plenum chamber. The flow is heated by an electric arc ignited between the electrodes and sustained by the ...
