Description
Verfahren zum Herstellen von Schmierkörpern zur Verwendung bei Warmstrangpressen von Stahlblöcken Es ist bekannt, zum Schmieren der Werkzeuge beim Warmstrangpressen von Stahlblöcken pulverförmige Schmierstoffe, wie Glaspulver, zu verwenden. Der an sich vorteilhaften - Verwendung glasartiger Schmiermittel in Pulverform steht im allgemeinen die Schwierigkeit entgegen; `dag Pulver in gleichmäßigen Schichten zwischen Preßblock und Matrize oder Preßstempel einzubringen. Besonders tritt diese Schwierigkeit beim waagerechten Strangpressen auf. Aus diesem Grund werden aus diesen pulverförmigen Schmierstoffen Formkörper hergestellt, z. B. Scheiben oder Ringe, und zwar durch Agglomerieren der Pulver oder unter Verwendung eines Bindemittels. Diese Formkörper gewährleisten die Ausbildung eines gleichmäßigen Schmierfilmes.Process for the production of lubricants for use in hot extrusion of steel blocks It is known to lubricate the tools during hot extrusion to use powdered lubricants such as glass powder from steel blocks. Of the Advantageous in itself - use of vitreous lubricants in powder form generally opposed to the difficulty; `dag powder in even layers to be introduced between the press block and die or ram. Especially this occurs Difficulty in horizontal extrusion. Because of this, these become powdered lubricants molded bodies produced, for. B. discs or rings, by agglomerating the powders or using a binder. These molded bodies ensure the formation of a uniform lubricating film.
In einem neuen, noch nicht bekanntgewordenen Vorschlag wird die Verwendung von Salzen oder Salzgemischen zum Schmieren beim Strangpressen von Stahl empfohlen, die einen Unwandlungspunkt aufweisen und die vor ihrem Gebrauch als Schmiermittel auf eine bei oder über dem Umwandlungspunkt liegende Temperatur erhitzt worden sind.In a new, not yet known proposal, the use of of salts or salt mixtures recommended for lubrication when extruding steel, which have a transformation point and which are prior to their use as lubricants have been heated to a temperature at or above the transition point.
Gegenstand der Erfindung ist ein Verfahren zum Herstellen von Schmierkörpern, wie Scheiben oder Ringen, durch Zusammensintern pulverförmiger Schmierstoffe für das Warmstrangpressen von Stahlblöcken, das erfindungsgemäß darin besteht, daß ein Gemisch aus pulverförmigem Alkalikarbonat oder -halogenid und 0,5 bis 5 Gewichtsprozent, vorzugsweise 0,3 bis 3 Gewichtsprozent, eines Salzes mit niedrigerem Schmelzpunkt, z. B. Natriumnitrat, in an sich bekannter Weise unter leichtem Druck bei Raumtemperatur in eine Form gepreßt und hierin bei einer Temperatur zwischen 400 und 800° C, vorzugsweise zwischen 550 und 600° C, gesintert wird.The invention relates to a method for producing lubricating bodies, like discs or rings, by sintering together powdered lubricants for the hot extrusion of steel blocks, which according to the invention consists in that a Mixture of powdered alkali carbonate or halide and 0.5 to 5 percent by weight, preferably 0.3 to 3 percent by weight, of a salt with a lower melting point, z. B. sodium nitrate, in a known manner under slight pressure at room temperature pressed into a mold and stored therein at a temperature between 400 and 800 ° C, preferably between 550 and 600 ° C, is sintered.
Eine Ausführungsform dieses Verfahrens besteht darin, daß eine Mischung von pulverförmigem Alkalikarbonat oder Alkalihalogenid und einer pulverisierten Schmelze einer aus verschiedenen Alkalisalzen, vorzugsweise aus Natrium- und Kaliumkarbonat, bestehenden eutektischen Verbindung gesintert wird. Schließlich kann auch eine Mischung gesintert werden, die 3 bis 5 Gewichtsprozent Wasser enthält.One embodiment of this method is that a mixture of powdered alkali carbonate or alkali halide and a powdered one Melt one of various alkali salts, preferably sodium and potassium carbonate, existing eutectic connection is sintered. Finally, it can also be a mixture be sintered, which contains 3 to 5 weight percent water.
Gegenüber den aus Glaspulver gesinterten Schmierscheiben weisen die nach dem erfindungsgemäßen Verfahren hergestellten Schmierkörper folgende besondere Wirkungen auf: Der Reibungsbeiwert beim Strangpressen beträgt nur etwa 50 bis 70% des bei Glasschmierung auftretenden Wertes. Die Preßkraft ist somit geringer, so daß größere Streckungen oder Preßgeschwindigkeiten möglich sind. Der Schmierfilm ist dünner.Compared to the grease washers sintered from glass powder, the The following special lubricants produced by the process according to the invention Effects on: The coefficient of friction during extrusion is only around 50 to 70% the value that occurs when the glass is smeared. The pressing force is therefore lower, see above that greater stretching or pressing speeds are possible. The lubricating film is thinner.
Die Oberfläche des Stranges ist glatter. (Bei Glas tritt meist die sogenannte »Apfelsinenhaut« auf.) Der Schmierfilm ist wasserlöslich und quantitativ z. B. durch Abspritzen mit Wasser entfernbar, was bei einer Schmierung mit Glas bekanntlich große Schwierigkeiten bereitet.The surface of the strand is smoother. (In the case of glass, the so-called »orange skin«.) The lubricating film is water-soluble and quantitative z. B. removable by spraying with water, which is when lubricated with glass known to cause great difficulties.
Beim Rückzug des Stempelkopfes aus dem Rezipienten tritt kein Verklemmen auf, da der Salzfilm sehr weich ist.When the stamp head is withdrawn from the recipient, there is no jamming because the salt film is very soft.
Gegenüber dem bekannten Vorschlag, Karbonate unter hohem Druck in die Strangpresse einzupressen, um das Ankleben des Werkstoffes an der Matrize bzw. am Dorn zu vermeiden, ist der Erfindungsgedanke, eine gesinterte Salzscheibe einzusetzen, leichter durchführbar, denn das bekannte Verfahren arbeitet mit flüssigen Karbonaten, was einen großen Aufwand an Heiz- und Druckaggregaten erfordert.Compared to the well-known proposal to use carbonates under high pressure in press in the extrusion press to prevent the material from sticking to the die or to avoid on the mandrel, the idea of the invention is to use a sintered salt disc, easier to carry out, because the known method works with liquid carbonates, which requires a lot of heating and pressure units.
Zur Schmierung von Pilgerdornen wurde Karbonat als Pulver aufgegeben. Ein Pulver ist bei horizontalen Strangpressen nicht anwendbar.Carbonate was used as a powder to lubricate pilgrim thorns. A powder cannot be used in horizontal extrusion presses.
Die nach dem erfindungsgemäßen Verfahren hergestellten Ringe oder Scheiben weisen nach dem Pressen und Sintern eine gute Haltbarkeit auf, was darauf zurückzuführen ist, daß die Festigkeit der Formkörper durch den Zusatz einer geringen Menge des niedriger schmelzenden Salzes um das Drei- bis Vierfache erhöht wird.The rings produced by the process according to the invention or After pressing and sintering, discs have a good shelf life, which is important is due to the fact that the strength of the molded body by the addition of a low Amount of lower melting salt is increased by three to four times.
Für den Fall, daß die Masse beim Sintern zu wenig schrumpfen sollte, klebt sie in der Preßform fest. Es hat sich gezeigt, daß die gesinterten Ringe oder Scheiben sich leicht aus der Form lösen und auch unbegrenzt gelagert werden können, wenn die Formkörper ein Porenvolumen von etwa 30 % aufweisen. Die gewünschte Dichte kann durch Mischen von feinem und grobem Alkalikarbonatpulver hergestellt werden.In the event that the mass should shrink too little during sintering, it sticks in the mold. It has been shown to be the sintered Rings or discs can easily be removed from the mold and can also be stored indefinitely can be if the shaped bodies have a pore volume of about 30%. the Desired density can be achieved by mixing fine and coarse alkali carbonate powder getting produced.
Werden z. B. etwa zwei Drittel grobkörnige (»schwere«) Soda mit einem Drittel feinkörniger (»leichter«) Soda unter Zugabe von etwa 3 Gewichtsprozent Natriumnitrat gemischt, so werden Formkörper erhalten, die nach dem Brennen sehr gut haltbar sind. weise 0,3 bis 3 Gewichtsprozent, eines Salzes mit niedrigerem Schmelzpunkt, z. B. Natriumnitrat, in an sich bekannter Weise unter leichtem Druck bei Raumtemperatur in eine Form gepreßt und hierin bei einer Temperatur zwischen 400 und 800° C, vorzugsweise zwischen 550 und 600° C, gesintert wird.Are z. B. about two-thirds of coarse-grained ("heavy") soda with a Third fine-grain ("lighter") soda with the addition of about 3 percent by weight sodium nitrate mixed, moldings are obtained which are very durable after firing. wise 0.3 to 3 percent by weight, of a salt with a lower melting point, e.g. B. Sodium nitrate, in a manner known per se, under slight pressure at room temperature pressed into a mold and stored therein at a temperature between 400 and 800 ° C, preferably between 550 and 600 ° C, is sintered.
2.
