With the increasing number of high productive EAF, and the variability in raw materials and product demand, the need for a system capable of adapting to the operation conditions in real time is essential. With state of the art technology, the AMIGE SmartFurnace system, featuring optimization tools like the DigitARC PX3 Electrode Regulation System and the ZoloSCAN Laser Off Gas Analyzer, has helped improve highly productive AC and DC furnaces.This papers discusses two implementations of the AMIGE SmartFurnace system. First, the installation of the SmartFurnace system in the 120t Double Shaft DC EAF in Yamato Steel Co. LTd., in Japan, including Electrode Regulator, and Chemical and Electrical Energy Optimization Modules. Second, the implementation of the SmartFurnace Off Gas Module in the 100t AC EAF in Vallourec Star, in the United States, based on an Off Gas Laser analyzer, for a closed loop control of the Chemical Energy input. The technology in these both cases is described, and the results are shown.
