Electric arc furnace (EAF) is one of the most disturbing loads in power system as it highly time-varying and nonlinear. In this paper, new models based on instantaneous EAF voltage current, recorded from EAFs Mobarakeh steel company Isfahan/Iran are proposed. The focus paper developing efficient Schwarz model where three modified types original has four constant parameters. Unlike which uses in...

BACKGROUND At present, the volumes of use electric arc furnace (EAF) dust are extremely insignificant. The their formation amount to thousands tons per month. During storage, they have a negative impact on environment. same time material that has valuable composition (oxides iron, non-ferrous metals, etc.) and is promising for recycling. However, secondary zinc-containing EAF in ferrous metallu...

This work describes the production of magnesia-alumina spinel using microwaves as energy source. The microwave energy was supplied by means of an 800 W magnetron operating at 2.45 GHz. The microstructure and the mineral composition were studied by means of SEM and X-Ray diffraction respectively. The resultant product shown sintered zone and incipient smelting of the reagents meaning that microw...
