Abstract: Provided are a method and an arrangement for operating a metallurgical furnace. The method comprises a feeding step, and a temperature controlling step for controlling the temperature of a molten metal layer and a slag layer in a furnace space of the metallurgical furnace. The temperature controlling step comprises a first measuring step for measuring the slag temperature (Tslag), a second measuring step for measuring the slag liquidus temperature (Tslag, liquidus), and a calculating step for calculating a superheat temperature (Tsuperheat) by calculating the temperature difference between the slag temperature (Tslag) and the slag liquidus temperature (Tslag, liquidus). In case the calculated superheat temperature (Tsuperheat) is outside a predefined superheat temperature range (Tsuperheat set), the method comprises an adjusting step for adjusting to adjust the actual superheat temperature. Also provided are computer program products.
