Abstract (en)
In a device for supporting meandering electrical heating conductors on the hot side of thermally insulating moulded bodies, consisting of ceramic fibres, in industrial furnaces, the heating conductors are supported by anchors in the regions of their bends, which anchors are arranged on the moulded bodies. In order to increase the positional security it is proposed that heating conductor supports be provided which are arranged between the bends (4) of the heating conductors (2) and at a distance from the bends (4), said supports being anchored in the moulded bodies (1) and engaging at least on the sides of the heating conductors (2) facing away from the hot side of the moulded bodies (1). <IMAGE>

Bei einer Vorrichtung zur Halterung mäanderförmiger, elektrischer Heizleiter an der heißen Seite von thermisch isolierenden Formkörpern aus keramischen Fasern in Industrieöfen sind die Heizleiter in den Bereichen ihrer Umlenkungen von Ankern gehaltert, die an den Formkörpern angeordnet sind. Zur Erhöhung der Lagesicherheit wird vorgeschlagen, zwischen den Umlenkungen (4) der Heizleiter (2) und mit Abstand von den Umlenkungen (4) angeordnete, in den Formkörpern (1) verankerte und mindestens an den der heißen Seite der Formkörper (1) abgewandten Seiten der Heizleiter (2) angreifende Heizleiter-Halterungen vorzusehen.
