Abstract
The thermal conductivity of slag is an important parameter in the
design of furnace-containment systems based on freeze-lining technology.
Literature indicates that the crystal content of a slag has a significant influence on
its thermal conductivity. Industrial, rich, manganese-bearing slag was cooled at
different rates to create samples with different microstructures. The coefficients of
thermal conductivity of these samples were measured in a nitrogen atmosphere
from room temperature to 990°C at 100°C intervals. The laser-flash measurement
technique was used for this purpose. Follow-up investigations included XRF and
XRD and modelling in FACTSage.
