Description

Rostschutzverfahren Die Erfindung bezieht sich auf ein Verfahren zum Überziehen von Metallgegenständen mit einer gegen Rost schützenden Haut durch Erhitzen in einem Metallpulver in Gegenwart von indifferenten Stoffen unter stetiger Bewegung. Von den bekannten Verfahren dieser Art unterscheidet sich das Verfahren gemäß der Erfindung dadurch, daß als indifferenter Stoff gepulverter Schmirgel verwendet wird. Schmirgel wird von der Hitze nicht angegriffen und ist hart genug, um den Stößen der zu behandelnden Gegenstände widerstehen zu können. Durch den Schmirgel werden die Zwischenräume zwischen den Bestandteilen während ihrer ständigen Bewegung nicht nur gebildet, sondern dauernd aufrechterhalten.Rust protection method The invention relates to a method for Covering metal objects with a skin protecting against rust by heating in a metal powder in the presence of inert substances with constant movement. The method according to FIG. 1 differs from the known methods of this type Invention in that powdered emery is used as the indifferent substance. Emery is not attacked by the heat and is hard enough to withstand the bumps to be able to withstand the objects to be treated. Be through the emery the gaps between the components during their constant movement do not only formed, but sustained permanently.

Dies bedeutet einen sehr wichtigen technischen Fortschritt, da das Mittel zur Erzeugung der Zwischenräume unbegrenzt lange benutzt werden kann, da man so die wirksamen Bestandteile voll ausnutzen kann, und da man schließlich bei Erneuerung derselben sicher ist, daß sie für den beabsichtigten Zweck nutzbar gemacht werden.This represents a very important technical advance as the Means for generating the interstices can be used indefinitely because you can take full advantage of the active ingredients, and then you end up with Renewal of the same is certain that it is made usable for the intended purpose will.

Ein weiterer Vorteil der Verwendung von Schmirgel ist, daß der Schmirgel nach der Korngröße ausgesucht werden kann und daß er wegen seiner Härte die Korngröße beibehält. Infolgedessen bleiben auch während der Bewegung der Bestandteile die Zwischenräume gleichmäßig im Gegensatz zu anderen Stoffen, wie feinem Sand, Tonerde o. dgl., welche dazu neigen, zu einer harten Masse zusammenzubacken. Es kann beispielsweise Schmirgel verwendet werden, welcher durch ein Sieb von io bis 16 Maschen auf den qcm hindurchfällt. Der Schmirgel wird von den zu behandelnden Gegenständen nicht aufgenommen, so daß nach jedem Arbeitsgang etwa die gleiche Schmirgelmenge in dem zur Ausübung des Verfahrens benutzten Gefäß, z. B. einem rotierenden Zylinder, zurückbleibt, und bei der neuen Beschickung des Gefäßes keine weitere Schmirgelmenge hinzugefügt zu werden braucht.Another benefit of using emery is that the emery is great can be selected according to the grain size and that it has the grain size because of its hardness maintains. As a result, the components remain even during the movement of the components Gaps evenly in contrast to other materials such as fine sand, clay or the like, which tend to bake together to form a hard mass. It can for example Emery can be used, which is passed through a sieve of 10 to 16 meshes on the qcm falls through. The emery is not from the objects to be treated added, so that after each operation about the same amount of emery in the vessel used to carry out the procedure, e.g. B. a rotating cylinder, remains, and do not add any more emery when loading the vessel again needs to become.

Zweckmäßig werden als zweiter Bestandteil reines Aluminium in fein pulverisiertem Zustande, als dritter Bestandteil ein Zinkstaub-Kupferniederschlag (durch Einbringen von Zinkstaub in eine Lösung von Kupfervitriol gewonnen) und als vierter Bestandteil feines metallisches Zinn (in reinem Zustande) verwendet. Es werden gewöhnlich noch die folgenden Salze hinzugefügt: Eisenchlorür, Kob,altchlorür -(sehr fein pulverisiertes Salz), Nickelsulfat (in fein verteiltem Zustande durch Chlorzink gefällt, das Ganze bis zur Trockenheit verdampft) und Antimontrichlorür. hie Temperaturen, welche bei normalen Abwärtsgängen zu verwenden sind, sind .etwa die folgenden: Die Temperatur soll so schnell wie möglich auf etwa 6oo° C gebracht und auf diesem Punkt nach der Anzeige eines Pyrometers etwa 30 Minuten lang erhalten werden.It is advisable to use pure aluminum in a finely powdered state as the second component, a zinc dust-copper deposit (obtained by adding zinc dust to a solution of vitriol) as the third component and fine metallic tin (in a pure state) as the fourth component. The following salts are usually added: iron chloride, cob, old chlorine - (very finely powdered salt), nickel sulphate (precipitated in a finely divided state with zinc chloride, the whole is evaporated to dryness) and antimony trichloride. The temperatures to be used in normal downward movements are approximately as follows: The temperature should be brought to about 600 ° C as quickly as possible and maintained at this point for about 30 minutes after the display of a pyrometer.

Dann soll die Temperatur langsam auf etwa 5oo° C gesenkt und auf diesem Punkt etwa 2o bis 30 Minuten erhalten werden.Then the temperature should slowly be lowered to about 5oo ° C and on this Point can be obtained about 20 to 30 minutes.

Es soll dann die Temperatur auf etwa 350° C gesenkt und für etwa 30 Minuten erhalten werden.The temperature should then be lowered to about 350 ° C. and maintained for about 30 minutes.

Wenn ein besonders schwerer Überzug der Legierung verlangt wird; dann soll die letzte Temperatur mehr als eine Stunde lang aufr echterhalten werden. Im allgemeinen sind aber die drei 'lerstgenannten Temperaturen und angegebenen Zeiten ausreichend.When a particularly heavy coating of the alloy is required; then the last temperature should be maintained for more than an hour. in the however, the three first-mentioned temperatures and times indicated are general sufficient.
