Die vorliegende Erfindung betrifft eine Verbesserung des Verfahrens zur Darstellung von walz- und schmiedbarem Flufsnickel und dessen Legirungen, welches durch das Haupt-Patent Nr. 73423 geschützt ist.The present invention relates to an improvement in the method for displaying rollable and malleable flufsnickel and its alloys, which by the main patent No. 73423 is protected.
Nach jenem Verfahren wird das entschwefelte Nickelbad in zwei Phasen — erst mit Luft und darauf mit einem Gemenge von Luft und Sauerstoff oder an Stelle dieses Gemenges in der zweiten Phase mit reinem Sauerstoff — geblasen.According to that process, the desulphurized nickel bath is made in two phases - first with air and then with a mixture of air and oxygen or instead of this mixture in the second phase with pure oxygen - blown.
Der Erfinder hat gefunden, dafs eine noch vollkommenere und vor allem auch viel raschere Reinigung des Nickelbades erzielt wird, wenn das vorerwähnte zweiphasige Blasen durch ein einphasiges, jedoch nur mit reinem Sauerstoff bewirktes Blasen ersetzt wird. Dieses Verfahren, wonach also das Nickelbad nach ■ dem Entfernen der schwefelhaltigen Manganschlacke ausschliefslich mit reinem Sauerstoff geblasen · wird, hat nicht nur den gewerblichen Vorzug gröfserer Einfachheit, sondern auch noch die wesentliche technische Bedeutung, dafs das in dem Nickelbade enthaltene Eisen, sowie das vom Zuschlage herrührende Mangan — gleichzeitig mit dem Kohlenstoff ■—'■ verbrennen und hierdurch nicht allein die Leichtflüssigkeit des Bades während des Blasens dauernd in bester Weise erhalten bleibt, sondern auch die Gesammtdauer des Blasens gegenüber dem zweiphasigen Blasen wesentlich abgekürzt wird.The inventor has found that an even more complete and, above all, much more rapid cleaning of the nickel bath is achieved if the above-mentioned two-phase blowing is replaced by a single-phase blowing, but only effected with pure oxygen. This process, according to which the nickel bath is blown exclusively with pure oxygen after the sulfur-containing manganese slag has been removed, not only has the commercial advantage of greater simplicity, but also the essential technical importance that the iron contained in the nickel bath, as well as that of the Additions originating manganese - burn at the same time with the carbon ■ - '■ and thereby not only the light liquid of the bath is permanently maintained in the best way during the blowing, but also the total duration of the blowing is significantly shortened compared to the two-phase blowing.
Auch das vorliegende vereinfachte Verfahren kann für die Gewinnung der Nickellegirungen, insbesondere Kupfernickel, in Anwendung kommen.The present simplified procedure can also be used for the production of nickel alloys, especially cupronickel, come into use.
