Electric arc furnaces are commonly used in steelmaking and in smelting of nonferrous metals. The electric power (10100 MW) depends by the length of the arc which can be controlled using an efficient hydraulic control system of electrode position. The Electric Arc Furnace (EAF) was historically the first application in the metallurgical industry to benefit from electromagnetic stirring. The technology was developed 70 years ago by ASEA (currently ABB), with the first commercial installation in 1947 at Uddeholm Utilize EAF's latest Tool Kit to create and maintain your organization's own Discipline Policy, plus develop procedure using our sample guide.

Electric Arc Furnace (EAF) is a steel making furnace, in which steel scrap is heated and melted by heat of electric arcs striking between the furnace electrodes and the metal bath. Two kinds of electric current may be used in Electric Arc Furnaces: direct (DC) and Induction/Arc Furnaces. 216 Pages·2010·5.44 MB·979 Downloads. Former Director, National Metallurgical Laboratory TGM for Induction/Arc/Cupola Furnaces Industry Electric arc steelmaking furnace uses electric energy as the main energy source. The electric energy is arc drawn through the discharge of graphite electrodes and the charge to generate high temperatures above 2000 ~ 6000 ?, and the scrap steel raw materials are An electric arc furnace is a system that heats charged material by means of an electric arc.

ELECTRIC ARC FURNACEELECTRIC ARC FURNACE:An Electric Arc Furnace (EAF) is a furnacethat heats charged material by means of anelectric arc.Arc furnaces range in size from small unitsof approximately one ton capacity Electric Arc Furnace. By: Marius Peens. Supervisor: Professor I.K. Craig. Master of Engineering(Electronic Engineering). This dissertation investigates the control of the electrical energy input to a three-phase electric arc furnace (EAF). Electric arc furnace with direct current (DC) operation has become popular in the recent days mainly because of its lower electrode consumption, stability of the arc, lower noise generation etc. In this furnace only one electrode is required to be located centrally which Electric arc furnace with direct current (DC) operation has become popular in the recent days mainly because of its lower electrode consumption, stability of the arc, lower noise generation etc. In this furnace only one electrode is required to be located centrally which The electric- arc furnace (EAF) is a squat, cylindrical vessel made of heavy steel plates. It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof (see figure ).
