Description
Beim Stranggießen von Metallen ,ist -es zur Erzielung eines einwandfreien Betriebsverlaufes von großer Bedeutung, die Kokillenwand gleichmäßig und ausreichend zu schmieren. Bei hochschmelzen-,den Metallen, wie Eisen und Stahl, muß insbesondere der Frage der gleichmäßigen Verteilung des Schmiermittels über den ganzen Umfang ,der Kokille eine ganz besondere Aufmerksamkeit gewidmet werden.When continuously casting metals, it is important to achieve a flawless The course of operations is very important, the mold wall is uniform and sufficient to lubricate. In the case of high-melting metals, such as iron and steel, must in particular the question of the even distribution of the lubricant over the entire circumference , special attention should be paid to the mold.
Die bisher bekanntgewordenen Vorrichtungen zur Einbringung .des Schmiermittels konnten ihren Zweck nicht immer voll erfüllen. So wurde z. B. vorgeschlagen, in der Innenwand der Kokille mit Hilfe eines aufgesetzten Ringes einen porösen Metallring vorzusehen, hinter welchem sich eine ringsum laufende Schmiermittelkammer befindet, .die durch eine Leitung mit einem Schmiermittelbehälter in Verbindung steht. Die Betriebssicherheit .dieser Anordnung ist vielfach nicht ausreichend, weil zufolge der unvermeidlichen Verrußung die Schmiermittelverteilung verhältnismäßig rasch ungleichmäßig wird.The previously known devices for introducing the lubricant could not always fully serve their purpose. So was z. B. suggested in the inner wall of the mold with the help of an attached ring a porous metal ring to provide, behind which there is a lubricant chamber running all around, .which is in communication with a lubricant reservoir through a line. the Operational safety. This arrangement is often not sufficient, because according to the inevitable sooting, the lubricant distribution relatively quickly becomes uneven.
Durch die Erfindung wird diese Schwierigkeit vermieden. Eine Ausführungsform derselben ist der Zeichnung zu entnehmen. Auf .die im obersten Teil abgeschrägte Kokille i wird einRingbehälter 2 aufgesetzt, dessen nach unten verlängerter Teil 3 der zylindrischen Innenwand mit der Innenwand .der Kokille einen schmalen Spalt 4 bildet. Dem Ringbehälter z wird in an sich bekannter Weise das Schmiermittel aus einemSammelbehälter durch eine Zuleitung 5 zugeführt. über dem Ringspalt 4 kann eine Schicht aus porösem Füllstoff 6, wie z. B. ,aus Glaswolle oder aus Glaswollgewebe, angeordnet sein, welche das Schmiermittel vor dem Eintritt in den Ringspalt 4, durch welchen es der Kokille zugeführt wird, passieren muß. Um nun eine völlig gleichmäßige Schmiermittelverteilung zu erreichen, wird dem Ringbehälter eine hin und her gehende Drehbewegung von höchstens i8o° erteilt.The invention avoids this difficulty. One embodiment the same can be found in the drawing. On the beveled in the uppermost part A ring container 2 is placed on the mold i, the part of which is extended downwards 3 of the cylindrical inner wall with the inner wall of the mold a narrow gap 4 forms. The lubricant is removed from the ring container z in a manner known per se fed to a collecting container through a feed line 5. over the annular gap 4 can a layer of porous filler 6, such as. B., made of glass wool or glass wool fabric, be arranged, which the lubricant before entering the annular gap 4 through which it is fed to the mold, must happen. To now a completely even To achieve lubricant distribution, the ring container becomes a reciprocating Rotational movement of not more than 180 ° granted.
Es ist ohne weiteres einzusehen, daß bei dieser Vorrichtung die Verrußungsgefahr bedeutend geringer ist als bei den bisher bekannten Vorrichtungen und daß durch die hin und her gehende Drehbewegung sowie durch das nach unten austretende Schmiermittel ein etwa im Ringspalt auftretender Ruß sofort beseitigt wird.It is readily apparent that with this device the risk of sooting is significantly less than in the previously known devices and that by the reciprocating rotary movement and the lubricant escaping downwards any soot that appears in the annular gap is removed immediately.
Es ist vielfach nicht notwendig, daß der Spalt für den Schmiermittelaustritt über den ganzen Kokillenumfang reicht, sondern es genügt häufig, wenn mehrere Austrittsöffnungen symmetrisch verteilt vorgesehen sind. Zwischen den Austrittsöffnungen liegt der nach unten verlängerte Teil der Innenwand des Ringbehälters, welcher mit der Kokille den Ringspalt bildet, an der Kokillenwan.d an. Bei .dieser Ausführungsform ist es erforderlich, daß die Winkelteilung der symmetrisch angeordneten Austrittsöffnungen kleiner ist als der Drehwinkel der hin und her gehenden Drehbewegung. Dieser soll zweckmäßig das Eineinhalbfache des Teilungswinkels für die Austrittsöffnungen betragen.In many cases it is not necessary for the gap for the lubricant to emerge extends over the entire circumference of the mold, but it is often sufficient if several outlet openings are provided symmetrically distributed. The is located between the outlet openings downwardly extended part of the inner wall of the ring container, which is connected to the mold forms the annular gap, on the Kokillenwan.d. In this embodiment it is required that the angular division of the symmetrically arranged outlet openings is smaller than the angle of rotation of the reciprocating rotary motion. This should expediently be one and a half times the pitch angle for the outlet openings.
