Abstract
In a metallurgical furnace of the type for re-heating metal billets and slabs, a pair of composite refractory tiles for insulating fluid-cooled structural members of the furnace. The tiles are a composite of a cast refractory shell which extends radially inward at selected portions to contact the furnace member. Attachment assemblies are embedded in the cast refractory shell and maintain proper alignment of each tile with the furnace structural member. In portions of the tile where contact with the furnace member is not made, a ceramic fiber insulating blanket fills a hollow between the refractory shell and the furnace member. Incorporating the ceramic fiber insulating blanket into each tile decreases furnace heat loss as compared to solid cast refractory tiles of comparable thickness.
