THE METHODS FOR MEASUREMENT OF THE SLAGS MELTING TEMPERATURE
Abstract
The submitted paper deals with methods of the melting temperature measurement, which is one of the most important physico – chemical properties of metallurgical slag systems. The paper is focused on two methods of melting temperature measurement using the high-temperature microscope and the thermocouple in Marsh furnace. The melting interval is measured using high temperature microscope while melting temperature is measured using the thermocouple in Marsh furnace. For experiment, slag systems similar to the Reactol 400/2 used as a refined tundish slag in Podbrezová Steel Plant were employed. It was found that both methods are suitable for measurement of the slag systems melting temperature to temperature 1450°C and using them gives reliable results.
