摘要: 应用粘性流体力学的基本原理,釆用专业流体力学软件FLUENT对160mmx160mm方坯连铸X 形浸入式水口对结晶器内钢水流动的影响进行数值模拟,验证了 X形浸入式水口浇注时,通过两块半椭圆形 导流板上、下平面与倒锥形圆筒内腔围成的螺旋形导流通道的导向作用,使钢水以涡流形式进入到结晶器,能 有效减轻钢水的冲击深度,有利于夹杂物、气泡聚集升浮和提高连铸效率。

Abstract: 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, and improve concasting efficiency.
