摘要
A pour passage of particular configuration for controlling the flow of aluminum-killed steels, or the like, is described which is effective for preventing the accumulation of oxide inclusions in an orifice opening disposed in the pour passage. The described pour passage configuration may be formed in a replaceable nozzle insert that is mountable in the pour opening of a molten metal teeming vessel or in the slidable panel of a sliding gate valve operably associated with the vessel. A method of preventing inclusion accumulation in a control orifice opening when pouring aluminum-killed steels or the like is also described.
