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.
