Patent ID: 6941653

Claim:
A method for forming a uniform lining of refractory material within the interior of a coreless furnace, comprising providing a lining form having walls dimensioned to provide a uniform space between the liner walls and the interior of the furnace; providing a carrier for the lining form, said carrier having a structure adapted for concentric location and attachment on top of a lining form, and for carrying the lining form when attached thereto, said carrier further having furnace engagement and locating means for engaging said furnace and locating said lining form, when attached, concentrically within the interior of the furnace, and further having a conical upper surface having an outer diameter substantially equal to the diameter of the lining form; attaching the carrier concentrically on top of the lining form; lowering at least part of the lining form into the interior of the furnace while engaging the furnace engagement and locating means of the carrier with said furnace, thereby concentrically locating said lining form within said furnace, and pouring particulate refractory material onto said conical upper surface, whereby the particulate refractory material is directed into the uniform space between the lining form and the furnace.
