Abstract

Zum Erschmelzen kleiner Metallmengen mittels Flamme dient eine Schmelzmulde (1) aus Keramikmaterial mit einer Senke (6, 6') und wenigstens einem während des Schmelzens nicht verschlossenen Gießkanal (2, 2'). In die im Betriebszustand mit Schmelze gefüllte Senke (6, 6') ragt ein durch eine Öffnung (8, 8') in der Muldenwand geführter Thermosensor (3, 3') mit Schutzmantel, wobei die Öffnung (8, 8') ebenso wie der Thermosensor (3, 3') sich unterhalb des Spiegels der Schmelze befinden. For melting small amounts of metal using a flame serves a melting trough (1) made of ceramic material with a depression (6, 6 ') and at least one during the Melting not closed pouring channel (2, 2 '). In the operating state with Melt-filled depression (6, 6 ') protrudes through an opening (8, 8 ') in the trough wall guided thermal sensor (3, 3 ') with protective jacket, the opening (8, 8 ') as well as the Thermosensor (3, 3 ') are below the level of the melt.
