Abstract
A ceramic fiber module, suitable for lining furnaces, comprises a weldable (metallic or perforate refractory) backing and a number of ceramic fiber mats cemented to the backing by the edge of the mat, so as to leave a portion of the backing accessible between mats or on their perimeter, for welding. The weldable backing is welded to a metallic substrate, preferably by use of spherical attachments, to provide thermal protection to the metallic substrate.
Claims19
A ceramic fiber module, comprising:
- (a) a weldable backing;
- (b) a plurality of ceramic fiber mats, each mat being substantially perpendicular to the backing, and all of the mats of a module being substantially parallel to each other;
- (c) adhesive, bonding at least a portion of one end of each ceramic fiber mat to the weldable backing, leaving a portion of the backing accessible;
- and
- (d) metallic spherical means for welding the backing to a metallic at the accessible position of the backing substrate.
