The liquid flow field and temperature field at center
nozzle surface and outlet of 420 mm x 1100 mm slab casting mold without injecting argon have been calculated by using FLUENT software
while distribution characters of liquid flow field and temperature field of mold with injeeting argon are calculated to optimize and get the optimum argon injecting flowrate of 3 L/min in mold. The test results in situ show that with injecting argon the distribution of liquid slag layer in mold is reasonable
the circulation of steel flow is better and the liquid surface is stable
as a result the crack rejection rate of casting slab decreases by 15%.
