Description

Elektrisches Heizelement und Verfahren zu dessen Herstellung Iaektrische I leizk(ii-1>er bestellen meist aus einem elelctrisclieii \\'iderstand und einem Trägerkörper zur _\ufnaltnte oder Ilefestigung des Widerstands. Ist der Widerstand aus Draht oder sotistwie aus \Ictall -eformt, so bestellt meist keine Schwierigkeit für einen Zusammenbau des Heizelements. Es -ibt jedoclt auch elekti-isclie Heizwiderstände, die aus Kolile, Metallpulvern oder anderen elektrisch leitenden Massen bestellen. Sie werden als llassewiderst;iti@le 1>ezeicliiiet und benötigen meist keinen "hr@igerk örlxr, wenn sie als selbsttragendes Bauteil entsl@recltcnde _\bniessungen und Festigkeit haben. Treffen diese \"oraussetzungen jedoch nicht zu, so ist es erfttrderlicli, solche I leizwiderstä ncie ebenfalls finit Tr:igerkö rl@ern zit I le@izelementen zu vereinigen.Electrical heating element and process for its manufacture Iaectric I leizk (ii-1> he usually order from an elelctrisclieii \\ 'resistance and a Carrier body for opening or strengthening the resistance. Is the resistance Made of wire or otherwise formed from \ Ictall, there is usually no problem for assembling the heating element. There are, however, also electrical heating resistors, which order from Kolile, metal powder or other electrically conductive masses. They are called lassewiderst; iti @ le 1> ezeicliiiet and usually do not need a "hr @ igerk örlxr, if it is a self-supporting component that desl @ recltcnde _ \ measurements and strength to have. If these \ "requirements do not apply, however, it is necessary to such I leizwiderstä ncie also finite Tr: igerkö rl @ ern zit I le @ izelemente to unite.

Die 1?rlindung bestellt darin, daß bei elektrischen Ilcizeleinenten, die aus einem elektrischen Widerstand und einem Trägerkörper bestehen, der elektrische Widerstand in formbarem Zustand in den Trägerkörper eingebracht und dann durch Wärmebehandlung erhärtet wird. Die Erhärtung kann dabei z.13. durch einen Brenn- oder Sinterungsvorgang durch lrw-ärinung von außen erfolgen. Es ist aber auch möglich, die Erwärmung durch Hindurchleiten eines so starken elektrischen Stroms herbeizuführen, daß die Erhärtung durch Wärme von innen erfolgt. Bei vielen Stoffen ist auch eine Er«°ärniung im f-loclifreqrienzfeld möglich.The effect of this is that in the case of electrical elements, which consist of an electrical resistor and a support body, the electrical Resistance in a malleable state introduced into the carrier body and then through heat treatment is hardened. The hardening can z.13. by a burning or sintering process done by external lrw. But it is also possible through the heating To bring about the passage of such a strong electric current that the hardening takes place through warmth from within. In the case of many substances there is also an annihilation in the field of loclifrequency possible.

Die Vorteile des Verfahrens gemäß der Erfindung liegen darin, daß es möglich ist, elektrische Heizwiderstände, die vor der Erhärtung aus pulvrigen oder teigigen Massen bestanden, in solchen Ausführungsformen herzustellen, wie sie bisher als selbsttragende Ausführungen nicht oder nur sehr schwierig herstellbar waren. Insbesondere ist es sehr einfach, gekrümmte oder sonstwie beliebig geformte Heizwiderstände herzustellen.The advantages of the method according to the invention are that it is possible to use electrical heating resistors that are made from powdery before hardening or doughy masses existed in such embodiments as they produce so far as self-supporting versions not or only very much difficult were producible. In particular, it is very easy to be curved or otherwise arbitrary manufacture shaped heating resistors.
