  Regenerationsmasse für überhitztes oder verbranntes Eisen und Stahl. 



   Es ist bekannt, verbrannten Stahl mit Gemischen von Harz, Kupfersulfat, Knochenmehl, Borax und Kochsalz zu regenerieren, wobei verhältnismässig viel von dem KupferSalz und weit weniger Knochenmehl und Salz für die Mischung vorgeschrieben wurde. Es hat sich jedoch herausgestellt, dass ein solches Gemenge nur   oherflächlich auf das Metall   wirkt und für Eisen völlig unbrauchbar ist. Der Stahl bekommt dabei ein ziemlich grobes Gefüge. Die Masse schmilzt nicht genügend und vermag deshalb auch nicht intensiv genug zu zementieren. Ausserdem wirkt ein Überschuss an   Kupfersl1lfat   nachteilig. 



   Es wurde weiterhin ermittelt, dass diese Masse verbessert wird, wenn an Stelle des Knochenmehles Kalziumphosphat, für Kochsalz das schwefelsaure Natrium tritt, wobei für beide Stoffe vorteilhaft der prozentuale Gehalt vergrössert wird, während   die Menge   des 
 EMI1.1 
 als sehr günstig erwiesen. 



   Dabei ist es wichtig, dass die Kupfersulfatmenge weit kleiner als die des Kalziumphosphates ist und auch das Natrisumulfat nicht übertifft. Besonders hat sich folgendes   Mischungsverhä) tnis bewährt   :   Terpenharz. 50   Teile   Kupfersnlfat.. 10

  Regeneration mass for overheated or burned iron and steel.



   It is known to regenerate burned steel with mixtures of resin, copper sulfate, bone meal, borax and table salt, with a relatively large amount of the copper salt and far less bone meal and salt being prescribed for the mixture. It has been found, however, that such a mixture only has a superficial effect on the metal and is completely useless for iron. The steel gets a fairly coarse structure. The mass does not melt sufficiently and therefore cannot cement intensely enough. In addition, an excess of copper sulfate has a disadvantageous effect.



   It has also been determined that this mass is improved if calcium phosphate is used instead of bone meal, sodium sulfuric acid is used for table salt, the percentage content being advantageously increased for both substances, while the amount of

 proved to be very cheap.



   It is important that the amount of copper sulfate is much smaller than that of calcium phosphate and that it does not exceed sodium sulfate. The following mixing ratio has proven particularly useful: terpene resin. 50 parts copper snuff .. 10

 phosphate and sodium sulfate.
