Possibility of a wide choice of original charge and variation of oxidation potential in melting process makes the electric arc furnace (EAF) a general-purpose unit in foundries. Energy-intensive classical technology with insufficient specific power of the transformer, irregular operation with forced downtime predetermine a low energy efficiency of foundry class furnaces [1,2]. Flat and shallow bath of the EAF enhances the problem.

Arc Furnace

A process and energy analysis was performed for an Electric Arc Furnace for steel production in order to determine the energy efficiency defined as losses contribution in the total energy input. Process analysis was performed during operation for one batch, measuring the relevant process parameters. Energy balance revealed that a significant potential for improvement exists, the main directions being reducing the cooling water loss (for example, by implementing a heat recovery system), reducing the loss during loading and adjustment by implementing technology changes and automation and reducing the loss through exhaust gas. Although implementation of heat recovery systems on the cooling water circuit and exhaust gas duct will not influence the actual process energy efficiency, it is expected to improve the overall energy expenditure by integrating other heat consuming equipment.

Industry Practice

Alloy scrap metal is increasingly being used in electric arc furnace (EAF) steelmaking and the alloying elements are also found in the resulting dust. A comprehensive characterization program of EAF dust has been undertaken in collaboration with the steel industry and AISI. Samples have been collected from the furnaces of 28 steel companies representing the broad spectrum of industry practice. The program aims to develop an understanding of the mechanisms of formation so that procedures to recover residual elements or recycle the dust can be established. The multi-phase, multi-component dust particles are amenable to individual particle analysis using modern analytical electron microscopy (AEM) methods.Particles are ultrasonically dispersed and subsequently supported on carbon coated formvar films on berylium grids for microscopy. The specimens require careful treatment to prevent agglomeration during preparation which occurs as a result of the combined effects of the fine particle size and particle magnetism. A number of approaches to inhibit agglomeration are currently being evaluated including dispersal in easily sublimable organic solids and size fractioning by centrifugation.
