ABSTRACT:
A method of mounting heating wire coils on ceramic fiber insulation walls. A ceramic fiber cement bead is applied in a desired pattern to the surface of a ceramic fiber wall, either directly to a flat surface or in a groove. An elongated iron-chromium-aluminum alloy heater wire coil is pressed into said cement so that the cement flows up and over the coil loops which contact the wall and the cement is cured. Because of the non-scaling (adherent Al.sub.2 O.sub.3 skin) characteristics of this heater wire alloy, the cement adheres tenaciously to the wire even under severe thermal shock and temperature cycling.
