Abstract: The present invention is related to a method for centering a pouring tube in a pouring tube assembly using a multi-piece centering sleeve by inserting a pouring tube into a holding casting aperture in a holding casting; pouring grout to fill a portion of a gap between the pouring tube and the holding casting; slipping the centering sleeve over the outside of the pouring tube until it is press fit in a portion of the gap between the pouring tube and the holding casting; adjusting the centering sleeve to center-position the pouring tube; grouting the remainder of the gap to fill all voids in the gap; installing a parting ring on top of the holding casting; and installing a holding ring around the holding casting and parting ring.

Abstract: The present invention is related to a pouring tube assembly. The pouring tube assembly comprises a holding tank assembly capable of containing a molten metal. A pouring tube is in flow communication with the holding tank assembly wherein the pouring tube is capable of receiving the molten metal from the holding tank assembly and depositing molten metal in a mold above the pouring tube. A sleeve is removably disposed between the pouring tube and a portion of the holding casting wherein the sleeve comprises mating sleeve portions with symmetrically disposed protrusions and recesses.
