Abstract
A method of pouring metal to provide improved physical properties is provided including the steps of: (a) pouring the metal through a generally vertical consumable tube extending from a pouring source to a point submerged beneath the surface of a molten pool in the receptacle, (b) continuously consuming the end of said vertical tube submerged beneath the surface of the molten pool to maintain a generally uniform portion of tube end submerged in said molten pool as pouring progresses of sufficient length to provide stirring action across substantially the full top area and to prevent the metal from flowing across the top surface as a flowing layer; and (c) removing said tube when pouring into the receptacle is completed. Slag components and/or alloy components are introduced into the metal in the tube to react with the metal.
