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...

In this paper, we study the establishment of AC electric arc furnace model via chaotic circuit. First, the static model based on energy conservation theory is established. Then, a dynamic model based on static model created previous is built to simulate AC electric arc furnace dynamic characteristics. Chua’s chaotic circuit is selected to generate modulation wave. The results obtained by using ...

Abstract. In this paper are study the modeling of a three phase electric arc furnace installation. It is well know that the electric arc is a nonlinear element. Thus, for modeling his behavior, the authors are using a model which parameters like of a real electric arc. For simulation it was use the PSCAD EMTDC program. The simulations results are comparing with the measurements made of a 100t e...

This paper introduces a multilevel STATCOM for electric arc furnace power quality enhancement. An eleven level cascaded multilevel converter is used to alleviate the impacts of an unbalanced arc furnace load. The STATCOM provides a power electronic-based means of embedded control for reactive power support.

The volatilization of zinc in the electric arc furnace dust–CaCl2 and ZnFe2O4–ZnO–CaCl2–C reaction systems was investigated. Experiments were conducted under an N2 atmosphere infrared lamp heating furnace, activation energy rate determined by Ozawa method. system 123 ± 27 kJ/mol; when dust decarburized, reduced to 84 4 kJ/mol. Further, simultaneous carbothermic reduction carbon contained chlori...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...
