Abstract: An attaching assembly is disclosed which permits attachment of ceramic fiber to a back plate. The assembly includes a stud retainer plate having a perforation, such as at the center of the plate. The stud retainer plate can be affixed to a perforate backing element, e.g., a metal mesh. On the side of the stud retainer plate opposite the backing element, there is a tube retainer. This tube retainer is secured to the stud retainer plate. An elongated, removable tube can be inserted into the tube retainer. A stud can be inserted through the removal tube, and through the retainer plate perforation and perforate backing element. The stud is then welded to a back plate, e.g., a solid furnace wall. A refractory element inserted in the retainer plate perforation insulates the stud from the retainer plate to prevent arcing during welding.

Abstract: An insulation supporting apparatus for use in attaching blankets of insulation to a surface, such as the wall of a high temperature furnace, including an elongated stud which can be attached at one end to the wall such as by welding or the use of a bolt, so that the stud extends perpendicularly from the wall, the stud having an elongated slot intersecting the plane of the stud longitudinal axis, and an elongated tine member slideably receivable in the slot in the stud so that the longitudinal axis of the tine extends substantially parallel the plane of the wall. The ends of the tine are pointed so that blankets of insulation can be impaled on the tine after which the stud and tines hold the insulation to th wall.

Abstract: This invention relates to a modular insulating article for insulating the interior of a high temperature furnace. The article comprises an outer shell-like form made of a ceramic fiber blanket, and interior layers made of ceramic fiber blanket material. The interior layers are disposed in planes which are parallel to the walls of the furnace. The layers are joined to each other and to the outer shell by means of an anchor pin and/or cement. The module is attached to the furnace wall by a mechanical anchor, preferably a "T" shaped stud, or refractory cement. The module has improved insulating value because of the disposition of the blankets and provides for the use of a high heat resistant blanket near the hot face and of lower cost high insulation blankets adjacent to the furnace wall.
