Numerical simulation on fluid flow in mold for wide slab continuous casting

Taking 150 mm×1 600～3 250 mm wide slab caster mold as an investigating object,the fluid flow in the mold of wide slab continuous casting is simulated by a three dimensional finite-volume model,which has been formulated according to the commercial code ANSYS CFX10.0.The effects of the casting speed,submergence depth,nozzle port angle,strand width on the flow field in mold are studied.The simulation results show that the increase of casting speed tends to raise the surface flow velocity and the impact pressure of narrow face.And larger port angle or submergence depth can bring about smaller surface fluctuation and less slag entrapment.
