ABSTRACT:
An elongated unitary refractory member having a horseshoe-shaped configuration is defined by opposing legs, each having a distal section, an interior surface adjacent to and extending between the distal sections, an outer surface and slot-like openings extending radially through the distal sections adjacent the interior surface. An interconnected reticulated metal structure is solidly embedded within the member and positioned adjacent the interior surface. A connecting plate is secured to the metal structure at each distal section and includes tabs in registry with the slots to permit access to the tabs for attachment to a water-cooled pipe or the like which is to be protected in a high temperature heat treating furnace.
