1. Verfahren zur Herstellung von Drähten aus Wolfram oder   dgl.,   insbesondere für die Zwecke der Glühlampenfabrikadon, durch Hämmern, Walzen und Ziehen der erhitzten Werkstücke, dadurch gekennzeichnet, dass die Werkstücke vor der mechanischen Bearbeitung, gegebenenfalls zwischen deren einzelnen Phasen, Gasen oder Dämpfen von   Schwefel, Solen,   Tellur oder deren Verbindungen (z.

   B.   Schwefelwasserstoff, Selenwasserstofi, Tellurwasserstofi)   oder von anderen ähnlich wirkenden Stoffen ausgesetzt werden, die auf den Werkstücken späterhin wieder restlos entfernbare Ablagerungen erzeugen, die die Oxydation der erhitzten Werkstücke verhindern. und das Walzen und Ziehen erleichtern, ohne dass eine schädliche Beeinflussung des   Werkstückmateriales   auftreten könnte.

 EMI2.1
 
1. A method for producing wires from tungsten or the like, in particular for the purposes of the incandescent lamp factory, by hammering, rolling and pulling the heated workpieces, characterized in that the workpieces prior to mechanical processing, optionally between their individual phases, gases or vapors of sulfur, brines, tellurium or their compounds (e.g.

   B. hydrogen sulphide, hydrogen selenium, hydrogen tellurium) or other substances with a similar effect, which later generate completely removable deposits on the workpieces, which prevent the oxidation of the heated workpieces. and facilitate rolling and drawing without the workpiece material being adversely affected.

Claims (1)

2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass die Gase oder Dämpfe in erhitztem Zustande angewendet werden, um gleichzeitig auch die Erhitzung der Werkstücke zu besorgen. 2. Embodiment of the method according to claim 1, characterized in that the gases or vapors are used in a heated state in order to also provide for heating of the workpieces at the same time. 3. Ausführungsforii des Verfahrens nach Anspruch 1. dadurch gekennzeichnet, dass die Werkstücke vor oder während ihrer Bearbeitung der Flamme von brennbaren Verbindungen. des Schwefels, Selens, Tellurs oder dgl. ausgesetzt werden. 3. Ausführungsforii of the method according to claim 1, characterized in that the workpieces before or during their processing of the flame of combustible compounds. of sulfur, selenium, tellurium or the like. Be exposed. 4. Verfahren zur Herstellung von Drähten aus Wolfram oder dgl., insbesondere für die Zwecke der Glühlampenfabrikation durch Hämmern, Walzen und Ziehen der erhitzten Werkstücke, dadurch gekennzeichnet, dass die Werkstücke vor ihrer mechanischen Bearbeitung, gegebenenfalls zwischen deren einzelnen Phasen von einer geschmolzenen Masse von Schwefel oder dgl. umhüllt werden, wodurch eine späterhin restlos entfernbare Umhüllung entsteht. die die Oxydation der erhitzten Werkstücke verhindert und die mechanische Bearbeitung, insbesondere das Ziehen. erleichtert. 4. A method for the production of wires from tungsten or the like., In particular for the purposes of light bulb manufacture by hammering, rolling and pulling the heated workpieces, characterized in that the workpieces before their mechanical processing, optionally between their individual phases of a molten mass of Sulfur or the like. Be encased, resulting in a later completely removable cover. which prevents oxidation of the heated workpieces and mechanical processing, especially drawing. facilitated.
