| Abstract: | A three-dimensional finite-difference model has been formulated, using the commercial code PHOENICS, to describe the fluid flow and heat transfer in the mold of a continuous slab caster.Through simulation and computation with the established simulation model, influences of such as casting speed, tilt angle of the nozzle port, immersion depth of the nozzle tube, size of nozzle port on flow field and temperature field in the mold were analyzed. On the basis above, a reasonable structure and size of nozzle was put forward for high speed continuous caster. |
