PROCEDE DE FABRICATION D'UN CORPS DE CHAUFFAGE PAR RESISTANCE ELECTRIQUE, ET CORPS DE CHAUFFAGE FABRIQUE SELON CE PROCEDE

摘要

The method according to the invention permits the simple and cost-effective production of a high efficiency electrical resistance heating element, by means of which workpieces which are pushed into the heating element can be heated. A heating element produced according to the method consists of a support (8) which is of stable shape, has an annular cross-section over its entire length and consists of a material which conducts heat well and of at least one heat conducting coil (2) whose heat conductor is surrounded in a shape-enclosing manner by a ceramic jacket (3) and whose turns are inserted in a shape-enclosing manner into the support wall, following the circumference of the support (8). <IMAGE>
