Modeling of electric arc furnaces (EAF) with electromagnetic stirring

, 2011
The influence of electromagnetic stirring in an electric arc furnace (EAF) has been studied. Using numerical modeling the effect of electromagnetic stirring on the thermal stratification and fluid flow has been investigated. The finite element method (FEM) software was used to compute the electromagnetic forces, and the fluid flow and heat and mass ...

Optimum charging materials for electric arc furnace EAF and Ladle Furnace LF system a simple case

, 2010
In this study, the thermo-economic optimization is accomplished on a steel production plant depending on the electric arc furnace (EAF) and ladle furnace (LF) used in a firm in Turkey. EAF and LF are taken as a system and mass balance is made by using literatures and firm catalogs. Cost functions based on energy and exergy were made for optimization.
