Abstract:
Electric Arc Furnaces" are of the most important industries in energy field. High energy consumption leads us to improve model for optimizing energy demand in electric arc furnaces. Melting and refining are two processes which need high amounts of energy. There are several different energy resources in electric arc furnaces. Materials can receive energy from electric arc or from chemical reactions that takes place between molten steel and slag. In addition, some slag formers should be added to the furnace. There are complicated relations between mass transfers, heat transfer and energy balance in EAF. In order to solve energy conservation problem in EAF, we should first extract equations to show this relations and then solve them. These equations are of Ordinary Differential Equation type. Then a computer program will solve these systems of equations. We need some initial conditions and geometrical information about EAF to run the program. After it, we can change different parameters and obtain results that guides us how to optimize energy demand in electric arc furnace
