Title: Mathematical model of the electric arc furnace. Final report

Abstract

Electric Arc Furnace Steelmaking is responsible for some 25% of the steel produced in the US and this proportion is likely to grow in the future. This operation consumes some 1.4 x 10/sup 10/ kWh annually at an overall process efficiency of about 60 to 75%. The purpose of this program has been to develop a mathematical model representing the energy transfer in electric arc furnaces with the objective of defining means for the optimization of the system, such that the energy consumption is reduced. Through the statement of the appropriate transport equations, subject to certain simplifying assumptions, a mathematical model has been developed to represent heat and fluid flow phenomena in the arc, the interaction of the arc with the bath, and bath circulation in electric arc furnaces. While there is a paucity of reliable information for the critical testing of the model as a description of industrial scale arc furnaces, there is enough data on plasmas, arcs and some industrial units to prove that the basic premises of the modelling effort are sound; indeed the predictions based on the model were found to be consistent with industrial scale measurements.
