Estimation of Steel Solidified Layer Thickness, for Continuous Casting Control Purposes
Zusammenfassung
An important goal in continuous casting automation process rest in
establishing a proper casting speed being able to assure a compromise between machine
productivity and solidified skin cracking protection on the mould level. Contextually,
this paper presents new solutions regarding solidified layer thickness estimation for
steel continuous casting. The new model starts from actual stadium analysis and
propose a solution for analytical model modification, in such a way that the model to
approximate solidification dynamics at different casting speeds, using both important
parameters for continuous casting process, meaning casting speed and time. A series of
results obtained using numeric simulation are presented as a validation for proposed
solution.
