Abstract: A high temperature, abrasion resistant insulating module is described having a sinuously folded, ceramic blanket with a lath covering three side of the folded blanket. The lath has doubled back portions extending into the folds of the blanket on it hot face. To the lathed front face of the folded blanket is applied a layer of thermally stable, abrasive resistant material which not only serves an as abrasion shield to the brittle fibrous material of the blanket, but only serves to stabilize the module and to reduce fiber dust.

Abstract: Ladle covers are insulated with refractory ceramic fiber modules. An outer portion of a lower part of the cover conforming to the shape of the ladle rim is insulated with trapezoidal modules. A central portion beneath the cover within the outer portion is insulated with rectangular modules, which may be of less thickness than the trapezoidal modules.

Abstract: Attachment structure is provided for mounting refractory ceramic fiber insulation units as components of ladle preheater insulating and sealing rings. The attachment structure provides a natural keying action with radial sliding motion of the insulation units during installation. The structure is particularly suitable for use on surfaces which are warped or uneven.

Abstract: Sealing rings are provided for ladle preheaters. The rings are mounted for relative movement into a stable, suspended position over the primary lining. Refractory fiber insulation is provided in the form of modules on an outer support ring. The rings seal about the ladle rim adjacent burner and flue openings of the preheater. Since the sealing ring may move over the primary lining, the ladle rim forms a seal with the modules and also forces the support ring into a second seal with the primary lining when the lining is refractory ceramic fiber.

Abstract: A method and apparatus for fastening an insulation module to a furnace wall. A stud member is welded onto the furnace wall. A pilot tool is attached to the stud member. An insulation module is impaled over the pilot tool and stud member. A nut is inserted onto the pilot member and threadably engages the stud member to secure the insulation module to the surface.

Abstract: Sealing rings for ladle preheaters. The rings may be either fixedly or removably mounted with the ladle preheater frame. The rings seal about the ladle rim adjacent burner and flue openings of the preheater. Refractory fiber insulation is provided for insulating the space between the rim of the ladle and the preheater to prevent hot gas escaping. The refractory fiber is arranged into trapezoidal units which are easily installed and replaced.

Abstract: Refractory fiber blankets are made suitable for use as baffles, curtains or partitions in furnaces and other high temperature equipment by reinforcement fabric woven from high temperature refractory fiber yarn. The curtains so formed are easily installed and replaced. The curtains exhibit insulation characteristics suitable for use at elevated (2200.degree. F. and above) temperatures and capabilities of resisting damage from impact by the furnace load or manipulators of such a load.

Abstract: Refractory ceramic fiber blanket modules with a continuous strip of ceramic fiber material folded into a number of layers in a serpentine fashion are used to insulate high temperature equipment. The blanket is supported by support structure which penetrates the blanket in the vicinity of folds near the furnace wall, providing increased strength against tearing away of the blanket from the supports.

Abstract: Refractory ceramic fiber blanket modules with a continuous strip of ceramic fiber material folded, such as into a number of layers in a serpentine fashion, are used to insulate high temperature equipment. The blanket is supported by support structure which penetrates the blanket in the vicinity of folds near the furnace wall, providing increased strength against tearing away of the blanket from the supports. The attachment structure of the module permits the module to be installed on non-planar or curved surfaces as well as planar or flat surfaces.

Abstract: Refractory fiber blanket blocks for electric furnaces having electrical heating elements mounted therewith by supports provide substantially improved insulation capabilities for electric furnaces when attached to the furnace walls. The support elements are in the form of holder members for receiving and support heating elements of the electric furnace and an arcuate spearing member which is capable of insertion into the insulative block at any desired location on an inner surface or hot face without requiring any anchoring structure for heating element support. The arcuate spearing member may take several forms and supports the heating element, engaging only the fiber blanket without anchoring structure for support.
