ABSTRACT:
An insulated door or wall panel assembly utilizes a compressively sandwiched array of bodies of insulation that extend side-by-side to define a substantially contiguous interior surface that can withstand direct exposure to high heat energy, for example by being positioned to extend about peripheral portions of a treatment chamber of a high temperature furnace to cooperate with adjacent furnace structure to minimize loss of heat energy from the treatment chamber. A rigid frame, typically formed from steel, overlies exterior portions of the sandwiched bodies of insulation and is securely connected thereto for positioning and supporting the array, whereby a rugged panel assembly is provided that is well suited for use as a closure to selectively permit access through a furnace wall opening to the treatment chamber. Included in the sandwiched array are a plurality of rigid cast refractory members that extend in spaced, substantially parallel relationship, with inner portions thereof defining a major part of the surface area of the interior surface of the panel assembly. Bodies of fiber-type refractory, typically in log-like form, are compressively sandwiched between adjacent ones of the cast refractory members. Such portions of the interior surface as are defined by inner portions of the cast refractory members store impingent heat energy received from the treatment chamber and serve to "re-radiate" stored heat energy back into the treatment chamber. Selected portions of the interior surface that are not defined by the cast refractory are defined by compressed stacks of bodies of fiber-type refractory that are securely connected to the frame.
