摘要
A method of preventing the accumulation of oxide inclusions on the flow surface of an orifice opening in a flow nozzle operably disposed in the pour passage of a teeming vessel for pouring a bath of Al-killed steels comprises the steps of forming the orifice opening of axial length shorter than that of the "vena contracta" of the molten metal stream flowing therethrough and providing a plenum about the orifice opening on the upstream side thereof defining a region in which the flow of molten metal is sufficiently stagnant to damp the vibration effects.
