Abstract (en)
A terminal-insulating module for use in an electric furnace consists of a refractory fibre mat (11) formed of discrete refractory fibres bonded together by an inorganic bonding agent and having a hot face (21), a cold face, and a plurality of side faces (25). A plurality of individual ceramic supports are partially embedded in the mat (11) and protrude outward from the hot face (21). The embedded portions are shaped so as to be firmly anchored within the mat (11), and the protruding portions (33, 35) are shaped to support an electrical resistance heating ribbon in the interior of the furnace. The modules are preferably formed in a felting box where the ceramic supports extend horizontally from cavities in the front wall. The layers of fibres build up upon a bottom screen in planes perpendicular to the hot face (21) of the module (11).
