| Abstract Scope |
This contribution focuses on the importance of obtaining accurate measurements of electrical conditions for the efficient operation of large electric furnaces. Despite the apparent reliability of the basic principles of electric control, the available direct and indirect measurements so not always yield trustworthy results. To address this limitation, this study developed specialized Finite Element Method models, which allowed to gain a better understanding of the electrical conditions within and around the furnace. To validate the model, a specific measurement campaign using Rogowski coils was conducted. These coils were placed on the bus-bar that feeds the electrode, providing unprecedented insight into the phases and currents of the electrodes. By comparing the results of the simulations with the existing measurements available at the industrial site, advancement of algorithms that control and optimize furnace operations can be devised. Ultimately, this work aims to enhance the overall efficiency of large electric smelting furnaces. |
