In according with production conditions for 60 mm thin slab concasting with 150 t ladle and 28 t tundish
the effect of outlet area ratio(2.0~2.4)
outlet angle(15°~35°)
immersed depth(210~270 mm)and casting speed (4.0~5.0m/min)on liquid flow field has been studied by using 1:2 water model test in orthogonal design to measure liquid surface wave amplitude in mode and pouring impact depth. Results showed that the optimized structure of submerged entry nozzle with cross outlet
of which outlet area ratio was 2.4 and outlet angle was 25°
was available to meet the requirement of high-speed casting with immersed depth 240 mm.
