Abstract
A protective refractory member for protecting heat-absorptive elements in a high-temperature furnace comprises a refractory shape, an interconnected, reticulated metal mesh embedded within the shape and positioned substantially adjacent an inner surface of the shape and at least one opening extending through a thickness of the shape and through the mesh. A tubular insert is located within the opening and is welded to the spirals which define the mesh. Both the insert and certain of the spirals engage the heat-absorptive element and the insert is welded to the element to retain the member thereto.
