AbstractGraphite carbon electrodes are of great importance as a crucial consumable ofElectric Arc Furnaces EAFs These electrodes have considerable impact on meltquality and production rate making a large amount of total costs Erosion andoxidation of these electrodes are primarily depended on working temperature However due to the high temperature and harsh environmental conditions of theEAF numerical thermal simulation techniques are often preferred to conventionalthermometry methods In this work temperature distribution within the EAFelectrodes was simulated using finite element method in 2D and 3D dimensions The effects of slag furnace sidewall refractory and the electrode parameters such aswater spraying at the end of electrodes were investigated Temperature distributionover the electrode surface was experimentally measured and compared to thesimulation results The influence of a thin TiN coating as a protective layer was alsosimulated The proximity effect of the graphite electrodes was analyzed using a 3Dthermal model Finally thermal stresses in the electrodes and mechanical effect ofTiN layer was analyzed using thermal structural couple analysis
