<P>PROBLEM TO BE SOLVED: To provide an insert for an electric furnace including a strand coil-like heater element, in which accumulation of expansion of the strand is prevented. <P>SOLUTION: An insert for an electric furnace includes a heat insulation shell and a coil-like heater element. A heater element (2) includes a strand comprising at least two sections connected to each other via a bending part (10) of the strand, so that the bending part (10) and sections (S<SB POS="POST">1</SB>, S<SB POS="POST">2</SB>) form a common strand loop. A fastening member (11) is fixed in the heat insulation shell and arranged in a region of the bending part (10), to avoid the strand in the sections (S<SB POS="POST">1</SB>, S<SB POS="POST">2</SB>) directly connected to the bending part (10) from being expanded beyond the fastening member (11). <P>COPYRIGHT: (C)2013,JPO&INPIT |
