Description

Legierung zur Herstellung von bearbeitbaren und hochsäurebeständigen Gegenständen. Zusatz zum Patent 387398. Die .Erfindung bezieht sich auf die Herstellung von hochsäurebeständigen und durch Späne abhebende Werkzeuge bearbeitbaren Gegenständen, wie u. a. Gefäßen, Röhren, Elektroden, Maschinen- und Apparateteilen, aus einer Kobalt-Silizium-Legierung gemäß ! Patent 387398, in welcher der Gewichtsanteil des Reinsiliziums nicht unter 32 Prozent herabgeht. Solange es sich um kleinere Gegenstände handelt, läßt sich deren Herstellung aus chemisch reinem Silizium und Kobalt unter den angegebenen Mischungsverhältnissen ermöglichen und auch noch wirtschaftlich ausführen. Die Beschaffung des reinen Siliziums bereitet aber Schwierigkeiten und i erfordert hohe Kosten. Hingegen ist das Silizium in Form von Ferrosilizium erreichbar und wirtschaftlich anwendbar.Alloy for making machinable and highly acid-resistant Objects. Addendum to Patent 387398. The invention relates to manufacture of highly acid-resistant objects that can be machined with tools that remove chips, like i.a. Vessels, tubes, electrodes, machine and apparatus parts, from one Cobalt-silicon alloy according to! Patent 387398, in which the weight fraction of the Pure silicon does not go below 32 percent. As long as they are smaller items is, their production from chemically pure silicon and cobalt can be omitted allow the specified mixing ratios and also economically carry out. The procurement of the pure silicon causes difficulties and i requires high cost. On the other hand, silicon can be obtained in the form of ferrosilicon and economically applicable.

Von den Ferrosiliziumkristallen ist nun bekannt, daß sie außerordentlich spröde sind. Versuche haben jedoch ergeben, daß diese Sprödigkeit durch Kobaltzusatz bedeutend gemildert wird; und zwar hat man, um durch '. Späne abhebende Werkzeuge bearbeitbare Legierungen zu erhalten, dem Ferrosilizium um so mehr Kobalt zuzusetzen, je stärker der Eisengehalt des benutzten Ferrosiliziums ist. Der Kobalthöchstgehalt soll auch in diesen Legierungen 42 Gewichtsprozente nicht überschreiten. Die Wahl des Mischungs- bzw. Gewichtsverhältnisses wird neben den vorstehend erwähnten rein technischen Gesichtspunkten der Säurefestigkeit und leichten Bearbeitungsmöglichkeit auch von wirtschaftlichen Gesichtspunkten beeinflußt.The ferrosilicon crystals are now known to be extraordinary are brittle. However, experiments have shown that this brittleness is caused by the addition of cobalt is significantly mitigated; and one has to get through '. Chip removing tools to obtain machinable alloys, to add more cobalt to the ferrosilicon, the stronger the iron content of the ferrosilicon used. The maximum level of cobalt should not exceed 42 percent by weight in these alloys either. The vote the mixing or weight ratio becomes pure besides those mentioned above technical aspects of acid resistance and ease of processing also influenced by economic considerations.
