Abstract

A two dimensional fluid flow heat transfer and solidification model has been developed for a curved shape continuous steel slab caster The strand has been divided in various sections depending upon cooling conditions in the mold and Secondary Cooling Zone SCZ The model was validated against the experimental results reported in the literature for solid shell thickness in the mold CFD software ANSYS Fluent has been used for solving the differential equations of heat transfer and fluid flow Surface temperature distribution has been predicted while the thickness of solid shell formed in the mold and SCZ has been calculated by finding the liquid fraction of steel within the domain Process parameters such as casting speed and cooling rate has been varied to analyse their effects on metallurgical length and solid shell thickness at the mold exit The analysis was based on keeping the shell thickness between 10 and 14 mm at mold exit and metallurgical length less than the cutoff length but having complete solidification after the straightening zone
