Description

Zementationsmittel Die Verwendung von Hitze, die durch die Verbrennung von Aluminium erzeugt wird, für die Reduktion bestimmter Metalloxyde und für die gleichzeitige Verschmelzung der gebildeten Metalle ist bekannt.Cementing Agent The use of heat produced by burning produced by aluminum, for the reduction of certain metal oxides and for the simultaneous fusion of the formed metals is known.

Eine völlige Erforschung der reduzierend wirkenden Reaktion solcher Metalle, wie Aluminium und/oder Magnesium, in Mischung mit verschiedenen Oxyden in einem geschlossenen Gefäß bei verschiedenen Temperaturen und bei Gegenwart von Gegenständen aus Gußeisen oder sonstigen Eisen- oder Stahlsorten; führte zu der Erfindung des Zementationsmittels. Bei der Anwendung des Zementationsmittels findet entsprechend den gewählten Oxyden eine Legierung der äußersten Schichten des behandelten Gutes mit Mangan, Nickel, Chrom, Titan, Wolfram u. dgl. statt.A full exploration of the reducing reaction of such Metals such as aluminum and / or magnesium mixed with various oxides in a closed vessel at different temperatures and in the presence of Objects made of cast iron or other types of iron or steel; led to the Invention of the cementation agent. When applying the cementation agent takes place Depending on the oxides chosen, an alloy of the outermost layers of the treated Good things happen with manganese, nickel, chromium, titanium, tungsten and the like.

Die Erfindung betrifft -ein Zementationsmittel für Eisen, in das die zu behandelnden metallisch blanken Teile in einem geschlossenen Gefäß. bei hoher Temperatur eingetaucht werden. Es besitzt erfindungsgemäß folgende Zusammensetzung i. go bis 98 ojö fein verteiltes Aluminium und/oder Aluminiumlegierung und/oder Magnesium in Mischung mit Oxyden oder oxydischen Erzen der dem Eisen einzuverleibenden Metalle, 2. 2 bis 1 o ()j0 Chloride eines oder mehrerer Metalle der zugemischten Oxyde. Der Anteil von Aluminium in der erstgenannten Mischung ist von der in den Oxyden enthaltenen Sauerstoffmenge abhängig. Der Anteil der bereits angegebenen metallischen Chloride schwankt je nach den gegebenen Verhältnissen zwischen 2 und i o Gewichtsprozenten der gesamten Mischung.The invention relates to a cementing agent for iron, in which the bare metal parts to be treated are placed in a closed vessel. be immersed at high temperature. According to the invention it has the following composition i. go to 98 ojö finely divided aluminum and / or aluminum alloy and / or magnesium in a mixture with oxides or oxidic ores of the metals to be incorporated into iron, 2. 2 to 1 o () j0 chlorides of one or more metals of the mixed oxides. The proportion of aluminum in the first-mentioned mixture depends on the amount of oxygen contained in the oxides. The proportion of the metallic chlorides already indicated varies, depending on the given ratios, between 2 and 10 percent by weight of the total mixture.

Die Temperatur in dem geschlossenen Gefäß, das den Zutritt der Luft verhindert, schwankt entsprechend den gegebenen Verhältnissen zwischen Aluminium und den Oxyden zwischen iooo und 1300'C. Die durch die Verbrennung reduzierten Metalle dringen in die Eisen- oder Stahlteile, die in unmittelbarer Berührung mit der Mischung stehen, ein und legieren sich mit diesen.The temperature in the closed vessel that allows air to enter prevented, fluctuates according to the given proportions between aluminum and the oxides between 100 and 1300 ° C. The metals reduced by the incineration penetrate the iron or steel parts that are in direct contact with the mixture stand, stand in and ally with them.

Je höher der Prozentgehalt an Metalloxyden in der Mischung ist und je länger die Arbeitstemperatur aufrechterhalten wird, um so tiefer ist das Eindringen.The higher the percentage of metal oxides in the mixture and the longer the working temperature is maintained, the deeper the penetration.

Die folgenden Stoffe können in geeignetem Mengenverhältnis als Grundstoffe der den eisernen Metallteilen einzuverleibenden Metalle dienen: für Titan Ilmenit, für Mangan calcinierer Pyrolisi_t, für Nickel entweder calcinierter Garnierit oder gerösteter nickeleisenhaltiger Pyrit, für Chrom gewaschenes und getrocknetes Chromeisenerz, für Wolfram Wolframit.The following substances can be used as basic substances in suitable proportions the metals to be incorporated into the iron metal parts are used: for titanium, ilmenite, for manganese calciner Pyrolisi_t, for nickel either calcined garnierite or roasted nickel-iron-containing pyrite, for chrome-washed and dried chrome-iron ore, for wolfram wolframite.

Eine Mischung dieser Stoffe in dem vorgenannten Verhältnis ermöglicht entsprechend der Wahl der Oxyde die Erzeugung eines Stahles mit einer durch Chrom, Nickel, Chrom und Nickel, Titan, Mangan, Titan und Mangan u. dgl. legierten Außenschicht.A mixture of these substances in the aforementioned ratio is made possible according to the choice of oxides the production of a Steel with one by chromium, nickel, chromium and nickel, titanium, manganese, titanium and manganese and the like. Alloyed outer layer.
