Abstract
Solidification and cooling of a continuously cast steel billet is a very complicated
problem of transient heat and mass transfer. The solving of such a problem is
impossible without a numerical model of the temperature field, not only of the
concasting itself while it is being processed through the caster but of the mold as
well. This process is described by the Fourier-Kirchhoff equation. An original
3D numerical off-line model of the temperature field of a caster has been
developed. It has graphical input and output - automatic generation of the net and
plotting of temperature fields in the form of color iso-therms and iso-zones, and
temperature-time curves for any point of the system being investigated. This
numerical model is capable of simulating the temperature field of a caster as
a whole, or any of its parts. Experimental research and data acquisition have to
be conducted simultaneously with the numerical computation—not only to
confront it with the actual numerical model, but also to make it more accurate
throughout the process. After computation, it is possible to obtain the
temperatures at each node of the network, and at each time of the process. The
utilization of the numerical model of solidification and cooling of a concasting
plays an indispensable role in practice. The potential change of technology—on
the basis of computation—is constantly guided by the effort to optimize, i.e. to
maximize the quality of the process.
Keywords: concasting, solidification, temperature field, numerical model.
