Patentirt im Deutschen Reiche vom 2. März 1901 ab. Längste Dauer: 13. Oktober 1914.Patented in the German Empire on March 2nd, 1901. Longest duration: October 13, 1914.
Das durch das Patent 118867 gekennzeichnete Verfahren kann in bestimmten Fällen wenig befriedigen, wenn das zuzumengende Flufsmittel einen so niedrigen Verdampfungspunkt hat, dafs es ganz oder theilweise während des Brennprozesses der Elektroden, der bekanntlich hohe Temperaturen erfordert, ausgetrieben wird. Aus diesem Grunde ist in der nachträglichen Anordnung eines der Natur der ausgeschiedenen Schlacken entsprechenden Flufsmittels in Form eines Mantels in einigen Fällen ein Vortheil zu erblicken und bildet unter Umständen eine Verbesserung des Hauptverfahrens.That characterized by the patent 118867 In certain cases, the procedure can not be very satisfactory if it is to be added Flux has such a low vaporization point that it is wholly or partly during the burning process of the electrodes, which is known to require high temperatures will. For this reason, in the subsequent arrangement there is a flux that corresponds to the nature of the separated slag to see an advantage in the form of a cloak in some cases, and under certain circumstances forms an improvement on the main process.
Ein weiterer Vortheil des Mantels liegt darin, dafs die von den harten Metallsalzen ausgeschiedenen Schlacken sich am äufsersten Rande der Kohlen abscheiden und dort unmittelbar unter den Einflufs des Flufsmittels gelangen.Another advantage of the mantle is that those precipitated from the hard metal salts Slag is deposited on the outermost edge of the coals and there directly get under the influence of the flux.
Insbesondere eignet sich das Verfahren bei Flufsmitteln, welche einen niedrigen Schmelzpunkt, wie z. B. Natriumsalze, haben, und es würde schwierig sein, dieselben in genügenden Mengen selbst den Kohlen imBrennprozefs beizufügen, um nach dem Brennen noch hinreichend Flufsmittel in den Elektroden zu besitzen.The method is particularly suitable for fluxes which have a low melting point, such as Sodium salts, and it would be difficult to obtain them in sufficient quantities Amounts to be added to the coals in the burning process in order to be sufficient after the burning To have flux in the electrodes.
