Control of Non - Ferrous Electric Arc Furnaces
An important aspect of non-ferrous metal production is the separation process known as smelting, in which the concentrated ore is melted and separated into two components of different densities: the slag and the matte. The smelting process is carried out through high-power heating in electric arc furnaces. In order to maintain a constant desired matte production rate and constant matte and slag...
متن کاملModeling of Three Phase Electric Arc Furnaces
Abstract. In this paper are study the modeling of a three phase electric arc furnace installation. It is well know that the electric arc is a nonlinear element. Thus, for modeling his behavior, the authors are using a model which parameters like of a real electric arc. For simulation it was use the PSCAD EMTDC program. The simulations results are comparing with the measurements made of a 100t e...
متن کاملMpc Control of the Refining Stage of an Electric Arc Furnace
The aim of this article was to design a MPC controller for the refining stage of an electric arc furnace. A reduced version of the generic EAF model will be used it simplifies the controller. The carbon content is controllable only in one direction it can only decrease asymptotically. The goal of the MPC controller will be to steer the temperature to the desired value before the carbon content ...
متن کاملModeling the Electromagnetic Pollution of the Electric Arc Furnaces
The electric arc furnace is a three-phase load representing one of the most important generator of harmonic currents, reactive power and unbalanced conditions in electrical power systems. This paper aims to achieve a study concerning the power quality of the energy at 3-phase electric arc furnaces. There are analyzed the main qualitative indicators of the electric power: power factor, reactive ...
متن کاملThe Effect of Foamy Slag on Power Consumption in Electric Arc Furnaces
In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...
