Abstract

The liquid flow field in mold of a 200 mm x 1 300 mm vertical slab caster and the effect of nozzle structure parameters (side hole size 40 mm x40 mm ~ 40 mm x80 mm

side hole angle +15° 〜-15°) with depth of submerged entry nozzle 115 mm and casting speed 0. 55 m/min on mold level fluctuation have been studied by using 1： 1 water mold

and based on calculation of fluid mechanics

the 3-dimensional numerical simulation of flow field in slab mold is carried out by using Fluent software and k-e high Re equation turbulence model. Results show that the numerical simulation results coincide with the results of physical simulation ； the effect of nozzle structure parameters on liquid level turbulent kinetic energy is obvious； in Nol ~ No4 nozzles

the service performance of No2 nozzle (40 mm x40 mm

+ 15°

downward

bottom with inverted Y shape) is relative better； and the shallower the strand impact depth

the larger free surface turbulent kinetic energy.
