| Abstract Scope |
Electric arcs are necessary for high Si yield operation in Submerged Arc Furnaces (SAFs) for Si/FeSi production, and a certain fraction of heat dissipation in the arc enables optimal operating conditions. Directly measuring the arc is impossible due to hostile conditions inside the SAF, so controlling the heat dissipation is both a science and an art. The arcs exhibit non-linear electrical characteristics and behave in a complex manner so by implementing a data acquisition (DAC) system to collect current and voltage waveforms, typically on the electrodes or transformers connections combined with appropriate signal processing offers an estimate the actual arc parameters, enabling improved understanding of the arcing in the furnace, and improve furnace operation. In this paper a DAC system gathering data from a FeSi SAF will be discussed, the data is processed and used to determine various furnace conditions including arc and charge current as well as harmonics. |
