Abstract
Description
Entstaubung eines Induktionsschmelzofens Wenn der abgesaugte Ofendeckel nicht um eine Achse drehbar gestaltet sondern geradeaus und etwa parallel zur Ofenplattform bewegt werden kann, wird die Saugleitung an einer Steile in der Verschiegungsrichtung geführt, wobei zwei Teilstücke toleskopartig in einander greifen.Dedusting an induction melting furnace When the furnace lid is vacuumed not designed to be rotatable about an axis but straight ahead and roughly parallel to the furnace platform can be moved, the suction line is at one point in the direction of displacement out, with two sections interlocking like a Toleskop.
In diesem Falle macht man die haube H quaderförmig, vorn, oben und gegenüber der Chargierseite geschlossen, auf der Chargierseite offen und setzt auf den Deckel eine rechteckige Saugwand, die also der Verschiebung des Deckels folgt und die bis knapp an die Innenseite der Haube reicht.In this case you make the hood H cuboid, front, top and closed opposite the charging side, open on the charging side and touches down the lid has a rectangular suction wall that follows the movement of the lid and that just reaches the inside of the hood.
Die Haube H kann sich parallel zum Deckel auf Schienen bewegen.The hood H can move on rails parallel to the cover.
Durch mechanisch oder elektrisch gesteuerte Riegel wird erreicht, dass die Haube H dem Deckel ganz oder teilweise folgt. Dadurch kann man die Ofenöffnung zum Entschlacken, Schmelzeabziehen oder Schmelzeeinfüllen teilweise oder ganz freigeben.Mechanically or electrically controlled bolts achieve that the hood H follows the cover in whole or in part. This allows you to open the oven opening for purification, removal of melt or pouring in of melt, partially or completely release.
Um beim Kippen des Ofens und teilweiser Öffnung die vom Ofen aussergalb der Haube aufsteigenden Gase'ins Innere der Haube zu leiten, wird am vorderen oberen DDd der Haube eine Klappe (K) angebracht, die sich schon durch die Schwerkraft öffnet und beim Horizontalstellen der Ofenplattform wieder schliesst, Bei horizontaler Stellung der Ofenplattform und völliger Zurückzi@hung von Deckel und Haube H wird die Klappe K durch einen mit ihr verbundenen Hebel geöffnet, der bei der genannten Haubenstellung auf eine kurze Schiene aufläuft0 Dadurch kann auch beim Einfüllen von Schmelze Gas in die Haube eingezogen werden.When tilting the furnace and partially opening the outside of the furnace The hood to conduct rising gases into the interior of the hood is at the front upper part DDd a flap (K) is attached to the hood, which already opens by gravity and closes again when the furnace platform is placed horizontally Position of the furnace platform and complete retraction of the cover and hood H the flap K is opened by a lever connected to it, which in the case of said Hood position on a short rail 0 This can also be used when filling be drawn into the hood by melt gas.
Man kann die Entstaubung des Ofens auch mit Hilfe einer Saugringes durchführen, der rund um die Ofenöffnung gelegt ist.You can also use a suction ring to remove dust from the oven around the oven opening.
Die Saugleitung wird dann gegenüber der Chargierseite unmtttelbar unter die Ofenplattform geführt, ohne einen Umweg über die Drehachse oder die Verschiebungsachse des Deckels nehmen su müssen. Notwendig ist jedoch, dass die Saugleitung an einer Stelle durch die verlängerte Drehachse der Ofenplattform läuft.The suction line can then be immersed in relation to the charging side guided under the furnace platform without a detour via the axis of rotation or the axis of displacement you have to take the lid. It is necessary, however, that the suction line is connected to a Place runs through the extended axis of rotation of the furnace platform.
Am Rande der Ofenöffnung wird auf die Ofenplattform eine rechteckige Saugwand aufgestellt, deren Abluft mit der Abluft des genannten Saugrings verbunden wird. Die Saugwand hat im unteren Teil eine Öffnung, durch welche der Deckel hindurchgeschonen werden kann. Bai völlig geöffnetem Deckel soll die Vorderfront der Saugwand und eine am Deckel angebrachte Abschluss.At the edge of the furnace opening, a rectangular one is placed on the furnace platform Set up suction wall, the exhaust air connected to the exhaust air of said suction ring will. The suction wall has an opening in the lower part through which the lid is protected can be. When the cover is completely open, the front of the suction wall and a closure attached to the lid.
wand eine geschlossene Fläche bilden.wall form a closed surface.
Die Oberhaube H soll so gelagert werden, dass sie mit dem Deckel verschiebbar ist. Sie muss etwas grösser sein als die Vorderfläche F von Saugwand und Ofendeckel zusammen. Sie kann durch gesteuerte Riegel so mit dem Deckel verbunden werden, dass sie die Tiegelöffnung ganz oder teilweise frei gibt.The top hood H should be stored in such a way that it can be moved with the cover is. It must be slightly larger than the front surface F of the suction wall and furnace lid together. It can be connected to the lid by controlled bolts in such a way that it releases the crucible opening in whole or in part.
