Abstract:
An electric furnace assembly, comprising at least one furnace wall and an elongated metallic resistor element being supported so as to extend adjacent to said furnace wall, said metallic resistor element being bent back and forth in its longitudinal direction so as to extend at a varying distance from said furnace wall, between extreme positions located at distal and proximal positions therefrom, said resistor element being retained at fixed points by fixed holding members, characterized in that said fixed holding members are adapted to fixedly hold said resistor element at said distal positions from said furnace wall, so as to permit a controlled elongation of said resistor element while keeping said resistor element within a limited region adjacent to said furnace wall, said limited region being confined substantially inside line segments extending between said fixed points, to thereby prevent the transfer of bending forces between adjacent portions of the resistor element.
