Dear Colleague
Jernkontoret is pleased to invite you
to the 6th European Oxygen Steelmaking
Conference in Stockholm,
Sweden 7–9 September 2011.
The European Oxygen Steelmaking
Conference (EOSC) series
is organised in turn by one of the
European Metallurgical Societies
and Associations. As such it represents
the most comprehensive expert
knowledge in steelmaking. This
conference is the successor to the
5th European Oxygen Steelmaking
Conference, held in Aachen in June
2006.
Located in Stockholm, Sweden
– one of the most beautiful cities
in Europe – this conference will
constitute a key event for oxygen
steelmaking specialists, including
those engaged in support systems.
The conference will present state
of the art technologies and developments
in specified technological
fields related to the specific requirements
of the oxygen steelmaking
process. The conference will include
keynote papers on world class
operations providing a global view
of the oxygen steelmaking industry.
The main focus of the conference
will be on practical results which
have come from experiments and
plant developments.
You are most welcome.
