Description

Vorrichtung zum Aufheizen von Gegenständen unter Verwendens von elektrischem Strom Die Neuerung bezieht sich auf eine Vorrichtung zum Aufheizen von Gegenständen unter Verwendung von elektrischem Strom. Zum Aufheizen von Gegenständen benutzt man Salzbäder, Widerstandsöfen, Lichtbogen-Öfen, Induktionsheiz- ofen usw. Diese weisen die nachstehend aufgeführten Nach- teileauf t Salzbäder haben den Mangel, daß sich das Salz aufbrauch und an dem erwärmten Werkstück festhaftet. Es ist erforder- licht die Art des Salzes in Übereinstimmung mit der Art des zu erhitzenden Werkstückes und mit der Heiztemperatur zu wählen. Außerdem besteht. wenn Wasser in das Bad geträufelt wird, die Gefahr einer Explosion des Salzes, ganz davon abgesehen,. daß der Betrieb und die Inbetriebhaltung des Bades schwierige und die laufenden Kosten hoch sind -.-l durchelektrische Wideratände ix Oten erzeugt wird und daher der mewirkungsgrad niedrig 1st.
