Description

Verfahren zur Herstellung elektrischer Widerstandskörper. Es ist ein Verfahren -zur Herstellung elektrischer Widerstandskörper aus nichtmetallischem Material, und zwar aus einer Mischung von Wasserglas, Kohle und Kreidepulver (oder einem ähnlichen Stoff) bekanntgeworden, dem als Aufnehmer für plötzlich gebildete Stromwärme Metall in feiner Verteilung zugefügt ist. Die Mischung wird in geeignete Form gebracht, erhärten gelassen und schließlich auf eine Temperatur von nicht unter 2oo° und nicht über 6oo ° so lange erhitzt, bis keine Gase mehr entweichen.Process for the production of electrical resistance bodies. It is a Process - for the production of electrical resistance bodies from non-metallic Material, namely a mixture of water glass, charcoal and chalk powder (or a similar substance) became known as a receptor for suddenly formed Electricity heat is added to metal in fine distribution. The mixture is in suitable Formed, allowed to harden and finally to a temperature not below Heated at 2oo ° and not above 6oo ° until no more gases escape.

Nach der Erfindung wird der Ausgangsmasse der Kohlenstoff mindestens teilweise an das Metall gebunden zugeführt. Zweckmäßig verwendet man dazu kohlenstoffhaltiges Eisen, welches den übrigen Stoffen zugesetzt und zusammen mit ihnen verarbeitet einen Widerstandskörper von vorzüglichen Eigenschaften ergibt.According to the invention, the starting material is at least carbon partially bound to the metal supplied. It is advisable to use carbonaceous material for this purpose Iron, which is added to the other substances and processed together with them results in a resistance body of excellent properties.
