Abstract
A heat-insulating panel is made by disposing a metal supporting member adjacent a felting screen to lay down a wet refractory fiber mat from an aqueous, refractory fiber-colloidal silica mixture about the metal member. The member has a central base section and a pair of wings extending in opposite directions from opposite edges of the central section, with the wings being disposed at an angle of between about 130.degree. and about 80.degree. to each other and each containing a plurality of holes. After drying, the member is embedded within the mat with individual fibers extending through the holes and firmly anchoring the member. The member is located adjacent the rear surface of the heat-insulating panel, and its central section contains an aperture through which a support rod is passed to mount the panel.
Claims6
A heat insulating panel having a front surface for placement facing the heat source and an opposite rear surface, which panel comprises
- a refractory fiber mat formed of discrete refractory fibers bonded together by an inorganic bonding agent, and
- a metal supporting member embedded within said fiber mat, which member includes a central base section and a pair of wing sections extending in opposite directions from said central section and being disposed at an angle of between about 25.degree. and about 50.degree. to said rear surface, said wing sections each containing a plurality of holes so that said individual fibers extend through said holes and thus firmly anchor said member as an integral part of said mat.
