INFLUENCE OF CASTING POWDERS ON THE THERMAL CONDUCTIVITY IN THE INGOT MOULD, THE SURFACE FINISH AND THE APPEARANCE DURING CONTINUOUS CASTING OF STEEL
With a parallel-plate-apparatus both a system thermal conductivity, which is believed to reflect the conditions in continuous casting, and an effective thermal conductivity of a casting flux layer are measured. To a certain extent, the effective conductivity can be seen as a material constant. There are considerable differences between the various casting powders which can be correlated to the SiO(2) and the FeO content. Increasing the SiO(2) content increases the conduction component of K(eff) while the radiation component is reduced by increasing the FeO content. No effect of chemical composition on the contact resistance of the interface flux layer mould was found.
