Abstract：To study how casting speed， immersion depth and width of crystallizer affect the level fluctuation with four-hole nozzle. Based on the slab caster crystallizer of 90 mm×1 500 mm and 90 mm×1 270 mm as prototype， the water model with 1[∶]1 scale was established， and data of steel-level fluctuation was collected by DJ800 data collecting system. The simulation results show that： The wave height in No.2 position sensor， with constant immersion depth， increases with the increase of casting speed； with constant casting speed， the wave height decreases with the increase of immersion depth from 240 mm to 340 mm. with constant casting speed and immersion depth， the smaller the crystallizer section， the smaller wave height.
