This paper presents a heat transfer study, based on the actual conditions of the hearth of Blast Furnace 2 at SSAB Oxelosund in Sweden. Initially, an experimental study was carried out. The temperature of the cold surfaces of the bottom and wall lining were measured with a hand-held thermocouple. The aim of the overall study was to find a method to determine the outer surface temperature, based on lining temperature readings from permanently installed thermocouples. A heat transfer model was developed, using the established correlations from the experimental study as boundary conditions. With the model, it is possible to calculate a complete two-dimensional temperature profile of the hearth lining at any given time. The permanently installed thermocouples are used to validate the model, by comparing calculated and measured temperatures; the accuracy of the model is plus/minus 3 degrees difference.
