Interfacial Properties in Metallurgy<br />
Investigation of the influencing factors for the wetting behaviour in solid, liquid<br />
and gaseous phases encountered in various processes of the iron- and steelmaking<br />
processes.<br />
Wetting experiments on various systems<br />
(reactive and non-reactive) are carried<br />
out in a tube furnace (max. temperature:<br />
1800°C) by means of the drop shape analysis<br />
approach. Moreover, since the wetting<br />
process depends largely on the surface properties<br />
of the substrate and its interactions<br />
with the spreading metal, a microstructural<br />
characterisation and analysis of the interfacial<br />
region is conducted with the help of<br />
optical and scanning electron microscopy.<br />

Metallurgy<br />
The core of the reseach activities is dedicated<br />
to the study of the wetting behaviour<br />
of liquid iron-based melts of varying<br />
chemistry on ceramic substrates with<br />
different surface roughnesses due to the<br />
importance of those systems in a number<br />
of metallurgical processes. Typical examples<br />
related to the continuous casting<br />
are the mechanisms of generation and<br />
removal from molten steel of non-metallic<br />
inclusions, the clogging of the submerged<br />
entry nozzle, as well as the local corrosion<br />
of the refractory linings at the metal/slag<br />
boundary.<br />
