| Description |
Development of a validated 3D transient mathematical model for modeling the fluid flow and solidifica-
tion process in an industrial continuous slab caster has been demonstrated. The model couples thermo-
fluid aspect of mold and sub-mold region by utilizing a standard Enthalpy-porosity method. Extensive plant
level measurements of mold heat fluxes and thermocouples data, breakout shell thickness profile, and
macrostructures were carried out to evaluate proper input of heat transfer and other conditions for the
model. A suitable validation of the model is established with slab surface temperature and solidified shell
thickness profile as measured from a breakout shell in the caster plant. An insight is drawn for an industrial
slab caster from the model results analysis for a range of operating parameters of casting speed and SEN
submergence depth as employed in the caster. Evolution of a solidified shell thickness profile is simulated.
Slab surface temperature mapping is drawn from the model and discussed its variation originating due to
fluid flow inside the solidified shell. Casting speed is shown to have a dominant effect as temperature rise
of order of 50°C are observed as it is increased from an average plant value of 1.4 m/min to peak of 1.8
m/min. Similar effect is also reflected in the solidified shell thickness profile as shell thickness gets thinner
by an order of 6 mm in the sub-mold region due to increase in casting speed from an average to peak
value. The effect of SEN submergence depth is also outlined.
