Numerical Simulation of Effect of X-Shape Submerged Nozzle on Flow of Molten Steel in Mold

Xiao Chao Cui, Yan Jin, Yanxia Chen

Abstract

The numeric simulation of effect of X-shape submerged nozzle on flow of molten steel in a mold for 160mm×160mm 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 semioval flow guidance plate and invert taper pipe to availably reduce impact depth, promote inclusion and gas bubble aggregating and floating off, and improve concasting efficiency.
