Description

Die Erfindung bezieht sich auf ein Verfahren entsprechend dem Oberbegriff des Anspruches 1 und auf eine Vorrichtung entsprechend dem Oberbegriff des Anspruches 3.The invention relates to a method according to the preamble of claim 1 and to a device according to the preamble of claim 3.

Bei einer bekannten Vorrichtung der vorgenannten Art besteht die Gefahr, daß beim Füllen des Warmhalteofens Verunreinigungen des schmelzflüssigen Gutes in die Kokille fließen, solange sich der Spiegel des schmelzflüssigen Gutes noch unterhalb des oberen Randes der Gießöffnung befindet (DE-OS 27 07 533).In a known device of the aforementioned type, there is a risk that contamination of the molten material will flow into the mold when the holding furnace is being filled, as long as the level of the molten material is still below the upper edge of the pouring opening (DE-OS 27 07 533).

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, beim Füllen des Warmhalteofens das übertreten von Verunreinigungen des schmelzflüssigen Gutes aus dem Warmhalteofen in die Kokille zu verhindern, solange sich der Spiegel des schmelzflüssigen Gutes noch unterhalb des oberen Randes der Gießöffnung befindet. Diese Aufgabe wird durch die Merkmale in den Kennzeichnungsteilen der Ansprüche 1 und 3 erfindungsgemäß gelöst.The present invention has for its object to prevent the contamination of the molten material from the holding furnace in the mold when filling the holding furnace, as long as the level of the molten material is still below the upper edge of the pouring opening. This object is achieved according to the invention by the features in the characterizing parts of claims 1 and 3.

Die die Gießöffnung verschließende Schmelzplatte verhindert beim Einfüllen von schmelzflüssigem Gut in den Warmhalteofen das Ausfließen dieses Gutes und von Verunreinigungen so lange, solange sich der Spiegel des schmelzflüssigen Gutes noch unterhalb des oberen Randes der Gießöffnung befindet. Das in den Warmhalteofen eingefüllte schmelzflüssige Gut übersteigt den schmelzbaren Teil der Schmelzplatte, ehe dieser geschmolzen ist, so daß aus dem geschmolzenen Teil der Schmelzplatte nur schmelzflüssiges Gut austritt, das keine auf ihm schwimmende Verunreinigungen mit sich führt.The melting plate closing the pouring opening prevents pouring out of this good and contaminants when pouring molten material into the holding furnace, as long as the level of the molten material is still below the upper edge of the pouring opening. The molten material filled into the holding furnace exceeds the meltable part of the melting plate before it has melted, so that only molten material emerges from the molten part of the melting plate and does not carry any contaminants floating on it.

Durch die Merkmale des Anspruches 2 wird erreicht, daß ein bestimmter Teil der Schmelzplatte schmilzt, bevor die ganze Schmelzplatte zum Schmelzen kommt. Aus dem nach dem Übersteigen durch das schmelzflüssige Gut geschmolzenen Teil der Schmelzplatte fließendes flüssiges Gut ist frei von Verunreinigungen. Hierdurch ist es möglich, anfangs einen kleineren Querschnitt als den von der Schmelzplatte bedeckten Querschnitt frei zu schweißen und mindestens anfangs einen kleineren Gutstrom in die Kokille fließen zu lassen. Die Dicke der Sollschmelzstelle und/oder der Schmelzplatte kann den jeweils gewünschten Temperaturen des schmelzflüssigen Gutes und dem Querschnitt der Kokille angepaßt werden.It is achieved by the features of claim 2 that a certain part of the melting plate melts before the entire melting plate melts. The liquid material flowing through the melted part of the melting plate after it has been exceeded is free from impurities. This makes it possible to initially weld a smaller cross-section than the cross-section covered by the melting plate, and at least initially to allow a smaller flow of material to flow into the mold. The thickness of the target melting point and / or the melting plate can be adapted to the respectively desired temperatures of the molten material and the cross section of the mold.

Ein Ofenmantel 1 ist aus Grobblechplatten zusammengeschweißt und mit feuerfesten Steinen 2 und einer Schicht 3 aus einer.feuerfesten Masse ausgekleidet. Der Warmhalteofen hat auf einer Seite eine Gießöffnung 22. Die Gießöffnung 22 durchsetzt eine auf dem Ofenmantel 1 befestigte gußeiserne Frontplatte 4. An dieser ist ein Zwischenflansch 5 (Fig. 2) mit Kokille 6 und dieser zugeordnetem Kühler 7 befestigt. An der Unterseite des Warmhalteofens ist ein am Ofenmantel fest angeschweißter Flansch zur Anbringung eines Induktors 9 vorgesehen. Auf der Oberseite des Warmhalteofens ist ein abnehmbarer Deckel 10 angeordnet, der mit einer feuerfesten Masse ausgegossen ist und einen Brennerstein 12 zur Aufnahme eines nicht dargestellten Brenners aufweist. Im unteren Bereich des Warmhalteofens ist eine Temperaturmeßstelle 13 vorgesehen, die ein Thermoelement 14 hat. Die Lage des Zwischenflansches 5 auf der Frontplatte 4 ist mittels Paßstiften genau festgelegt. Der Bereich zwischen der Kokille 6 und der die Steine 2 bedeckenden Schicht 3 wird durch einen von einem Isolierkörper 16 umgebenen Zuführtrichter 17 überbrückt. Der Isolierkörper 16 besteht aus einer Isoliermasse und der Zuführtrichter 17 aus einer feuerfesten Masse. An der Stoßstelle zwischen der Mündung der Gießöffnung 22 und dem Zuführtrichter 17 sind die lichten Ausnehmungen jeweils gleich. Hier ist eine Schmelzplatte 25 eingesetzt, die die Gießöffnung 22 ausfüllt und von dem Zuführtrichter 17 gehalten wird. Die Schmelzplatte 25 hat an der Unterseite eine Sollschmelzstelle 26 geringerer Dicke. Der Werkstoff der Schmelzplatte 25, deren Dicke und die Dicke der Sollschmelzstelle ist den das schmelzflüssige Gut jeweils aufweisenden Temperaturen und den Querschnitten der Kokille 6 angepaßt.A furnace jacket 1 is welded together from heavy plate and lined with refractory bricks 2 and a layer 3 of a refractory mass. The holding furnace has a pouring opening 22 on one side. The pouring opening 22 passes through a cast iron front plate 4 fastened to the furnace casing 1. An intermediate flange 5 (FIG. 2) with a mold 6 and a cooler 7 associated therewith is fastened thereon. On the underside of the holding furnace, a flange is permanently welded to the furnace jacket for attaching an inductor 9. On the top of the holding furnace, a removable cover 10 is arranged, which is filled with a refractory mass and has a burner block 12 for receiving a burner, not shown. In the lower area of the holding furnace, a temperature measuring point 13 is provided, which has a thermocouple 14. The position of the intermediate flange 5 on the front plate 4 is precisely determined by means of dowel pins. The area between the mold 6 and the layer 3 covering the stones 2 is bridged by a feed hopper 17 surrounded by an insulating body 16. The insulating body 16 consists of an insulating compound and the feed funnel 17 consists of a refractory compound. At the joint between the mouth of the pouring opening 22 and the feed funnel 17, the clear recesses are each the same. Here, a melting plate 25 is used, which fills the pouring opening 22 and is held by the feed hopper 17. The melting plate 25 has a predetermined melting point 26 of reduced thickness on the underside. The material of the melting plate 25, its thickness and the thickness of the target melting point is adapted to the temperatures and the cross sections of the mold 6, respectively, which have the molten material.

Zwischen der Frontplatte 4 und dem Zwischenflansch 5 ist eine Dichtung 19 in Form einer Asbestplatte oder dgl. vorgesehen. Der die Kokille 6 umgebende Kühler 7 ist mit seinem Flansch an einem Haltering 20 mittels Schrauben lösbar befestigt, der seinerseits an dem Zwischenflansch 5 ebenfalls mittels Schrauben lösbar befestigt ist. Zum Ausrichten der Kokille können am Befestigungsflansch des Kühlers 7 Langlöcher vorgesehen sein. Es ist möglich, an dem Zwischenflansch 5 mehrere Kokillen 6 anzuordnen.A seal 19 in the form of an asbestos plate or the like is provided between the front plate 4 and the intermediate flange 5. The cooler 7 surrounding the mold 6 is releasably attached with its flange to a retaining ring 20 by means of screws, which in turn is also releasably attached to the intermediate flange 5 by means of screws. To align the mold 7 slots can be provided on the mounting flange of the cooler. It is possible to arrange several molds 6 on the intermediate flange 5.

Beim Einfüllen von schmelzflüssigem Gut in den Warmhalteofen 1 übersteigt dieses die Sollschmelzstelle 26 und die Schmelzplatte 25 jeweils bevor die Sollschmelzstelle 26 bzw. die Schmelzplatte 25 schmilzt. Dadurch wird verhindert, daß auf dem schmelzflüssigen Gut, insbesondere Metall, schwimmende Verunreinigungen, insbesondere Schlacke, in die Kokille fließen. Die Gießöffnung 22 ist derart ausgebildet, daß sich beim Füllen des Warmhalteofens keine Verunreinigungen darin fangen und diese von dem die Gießöffnung 22 übersteigenden schmelzflüssigen Gut mitgenommen werden. Die Sollschmelzstelle 26 und die Schmelzplatte 25 schmelzen jeweils nach einer vorbestimmten Zeit. Die Schmelzplatte 25 kann auch ohne Sollschmelzstelle 26 ausgebildet sein.When pouring molten material into the holding furnace 1, this exceeds the target melting point 26 and the melting plate 25 before the target melting point 26 or the melting plate 25 melts. This prevents contaminants, in particular slag, floating on the molten material, in particular metal, from flowing into the mold. The pouring opening 22 is designed in such a way that no contaminants get caught in it when the holding furnace is being filled and these are carried along by the molten material exceeding the pouring opening 22. The target melting point 26 and the melting plate 25 each melt after a predetermined time. The melting plate 25 can also be designed without a predetermined melting point 26.
