The numeric simulation of effect of X-shape submerged nozzle on flow of molten steel in a mold for 160 mm x 160 mm concasting billet has been carried out by viscous fluid mechanics theory and CFD software Fluent. It was verified that during pouring with X-shape submerged nozzle
the vortex molten steel entering into mold by guide of vortex guidance channel which was formed with top and bottom surface of two semi-oval flow guidance plate and invert taper pipe to availably reduce impact depth
promote inclusion and gas bubble aggregating and floating off
