| Summary: | Continuous casting of steel billets, blooms and slabs is one of the dominant
processes in the steel making industry. Production of high quality steel with no defects,
has become a very important issue in the current highly competitive market conditions. To
satisfy quality control standards, steel mills must now incorporate "state of the art"
technologies in continuous casting. New techniques from different fields are being applied
to the process to assist in casting "perfect" steel.
Computers are now essential elements in applying advanced technologies for
process and quality improvements. In this work, an attempt has been made to create an
intelligent Supervisory Control and Data Acquisition System (SCADA) for the billet
casting process. The "brain" of this system consists of an Artificial Intelligence entity that
combines low-level numerical processing of sensor inputs with high-level symbol
processing, ie. an Expert System The mastered process knowledge and experience, along
with intelligent numerical computation, have been captured into a system called "Smart"
Mould.
This thesis focuses on the evolution of the hardware framework and software
support for the SCADA system The concept of intelligent computation as a prerequisite
to intelligent process control with respect to the continuous casting of steel billets is also
introduced. === Applied Science, Faculty of === Mining Engineering, Keevil Institute of === Graduate
