Modeling and Control of an Electrode Regulation System for an Electric Arc Furnace
, M.Sc. Thesis Sharif University of Technology ; Salarieh, Hasan (Supervisor) ; Alasty, Aria (Supervisor)
Abstract
Rate of steel production in each country could lead us to rate of growth and development of that country. Having magnetite and hematite mines, inexpensive energy and labor, make steel production more feasible in Iran; so using technology to reach efficient production should be considered by clients.
Electrode regulation system controls the main input energy to electric arc furnace, i.e. electrical energy. Using this system could decrease tap to tap time and increase plant productivity. In present study, after brief review of literature, mathematical model for electrical and hydraulic model derived, and then different controllers designed for combination of these models. Results show good...

Abstract
Cold Briquetted Iron and Carbon (CBIC) is a new product in Direct Reduced Iron (DRI) family that aims to produce a reliable product from Cold Direct Reduced Iron (CDRI) with the ability of low risk, high efficient storage and handling. In this study, a comprehensive investigation was carried out on the effects of environmental condition on physical and chemical properties of CBIC, CDRI and Hot Briquetted Iron (HBI) in the first step and then, the steelmaking performance of this new product was compared to the other DRI products in the second step. The changes of microstructure, specific surface area, metallization degree and mechanical strength of different products with time in dry and...
