Numerical simulation on the surface fluctuation of molten steel in a wide slab continuous casting mold

The effect of the angle of submerged entry nozzles,casting speed,and cross-section width of slabs on the surface fluctuation in a mold of Anyang Iron Steel was researched with the VOF model of commercial software ANSYS CFX10.0.The results show that with the mold width increasing from 1 800 mm to 3 250 mm,the average wave height of liquid level in the mold decreases significantly.When the width is 1 800 mm,the average wave height of the mold flux-molten steel interface is 5.33 mm;when the width is 3 250 mm,the average wave height is 7.08 mm.
