ABSTRACT:
A refractory fiber module retainer system and a method of forming such retainer system is disclosed; the system includes a unitary refractory fiber module possessing substantial rigidity; the module being formed, such as by molding to have a perforated support means embedded within the module, and with a suitable bore for enabling the required fastening of the module to a furnace shell or the like. The system further includes a stud as part of the fastening means, said stud being passed through the bore and through an opening in the support means such that the stud can be readily welded to the furnace shell after the module has been placed against the shell. A locking means is locked into place on the free end of the stud, which end is located deep within the bore. A plug is fitted into the bore at the inner or "hot" face of the module, thereby to prevent corrosion of the fastening means; likewise, to preclude heat transfer from the interior of the furnace to the furnace shell.
