Our system gathers light, analyzes it, and provides optimal control for your EAF process. All this happens in real-time to match ever-changing process conditions. With real-time light-based control, you can achieve reduced process times, improved energy efficiency, and decreased CO2 emissions.\\r\\n\\r\\nThe process temperature in the ladle furnace and the chemical composition of the slag directly affect the quality of the final product.  With Luxmet\\u2019s ArcSpecLF, you can monitor and control both continuously and in real-time. Using OES, ArcSpecLF distinguishes various spectra within the furnace, including thermal radiation, alkali peaks, and atomic emissions.\\r\\n\\r\\nTempSpec is a cutting-edge real-time continuous temperature measurement system, designed for the most demanding high-temperature metallurgical environments. Whether you\\u2019re dealing with intense slag splashes, rapid temperature shifts, or other challenging conditions, TempSpec ensures reliable and accurate temperature monitoring. With contactless measurement heads, TempSpec provides real-time temperature data which can be used for process optimization. Additional process data or spectrum diagnostics can also be used to compensate for the impact of process conditions.
