Numerical Simulation on Level Fluctuation in Mold for Wide Slab Continuous Casting

Based on the 150 mm×(1 600~3 250) mm wide slab caster mold as investigating object,the level fluctuation in the mold of the wide slab continuous casting was simulated by a three dimensional finite-volume model(VOF) which had been formulated according to the commercial code ANSYS CFX10.0.The effects of the casting speed、nozzle port angle、strand width on the level fluctuation in the mold had been studied.The simulation results show that with increasing of casting speed or width of strand,the wave height was enhanced.and the larger nozzle port angle,the smaller level fluctuation.
