Ferro<strong>chromium</strong> ProductionFigure 4:The Power Density Profile of a Submerged-Arc Furnace Around the Electrodes.5 VALIDATIONData were <strong>co</strong>llected from <strong>in</strong>dustries to validate the simulator. Figure 5 <strong>co</strong>mpares the quantity of metalproduced predicted by the simulator with that reported by the Plant. Though there is scatter <strong>in</strong> eitherdirection, the two sets of data agree with each other with an average deviation of 1.65%. Similaragreement is seen between the sets of data with respect to the <strong>co</strong>mposition of the slag as well as theheat required for the process as demonstrated <strong>in</strong> figures 6 and 7. Consider<strong>in</strong>g the <strong>co</strong>nsiderabledifficulty <strong>in</strong> generat<strong>in</strong>g dat with high accuracy <strong>in</strong> <strong>in</strong>dustrial operation, the agreement between thevalues predicted by the simulator and the data reported by the plant is <strong>co</strong>nsidered to be excellent.The Twelfth International Ferroalloys CongressSusta<strong>in</strong>able Future407June 6 – 9, 2010Hels<strong>in</strong>ki, F<strong>in</strong>land
