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

Zur Person:
Diploma and Ph.D. in Metallurgy (MUL)
Industrial experience (3 years) at ISCOR Flat Products
Currently: Postdoctoral Research Associate at the Chair of
Metallurgy
The core of the reseach activities is dedicated
to the study of the wetting behaviour
of liquid iron-based melts of varying
chemistry on ceramic substrates with
different surface roughnesses due to the
importance of those systems in a number
of metallurgical processes. Typical examples
related to the continuous casting
are the mechanisms of generation and
removal from molten steel of non-metallic
inclusions, the clogging of the submerged
entry nozzle, as well as the local corrosion
of the refractory linings at the metal/slag
boundary.
