Abstract
Description
Die Erfindung betrifft eine Vorwärmeinrichtung für in einem Schmelzofen zu schmelzende Masseln.The The invention relates to a preheating device for in ingots to be melted in a melting furnace.
Die in einem Schmelzofen für eine spätere Weiterbearbeitung aufgenommene Schmelze, z.B. Magnesiumschmelze wird durch Einführen von Masseln in die Schmelze aufgefüllt. Diese festen Masseln schmelzen aufgrund der Wärme in dem Schmelzofen. Damit die Temperaturdifferenz zwischen der Schmelze und den Masseln nicht zu groß ist, werden die Masseln in einem Vorwärmofen aufgeheizt. Masseln, insbesondere Magnesium-Masseln werden auf Paletten gesetzt geliefert. In der bisherigen Praxis werden die Masseln je nach Bedarf manuell von den Paletten genommen und entweder in die Vorwärmöfen eingelegt oder auf dem Schmelzofen aufgelegt, damit die Masseln über eine Temperatur von 10 0 ° C kommen.The in a smelting furnace for a later further processing absorbed melt, e.g. Magnesium melt is made by introducing Ingots filled in the melt. These solid pigs melt due to the heat in the smelting furnace. In order to the temperature difference between the melt and the pigs not is too big The pigs are in a preheating oven heated. Bullocks, especially magnesium ingots are on pallets delivered delivered. In the past practice, the ingots are ever Manually taken from the pallets as needed and either in the Preheating oven inserted or placed on the furnace, so that the pigs over a Temperature of 10 0 ° C come.
Bekannte Vorwärmöfen sind mit Heizplatten ausgestattet, wobei hier die Gefahr besteht, dass die Masseln punktuell überhitzt werden, da der Wärmeaustausch über Strahlungswärme erfolgt, was zu einem Magnesium-Brand im Vorwärmofen führen kann.Known Vorwärmöfen are equipped with hotplates, where there is a risk that the masses overheated at certain points since the heat exchange takes place via radiant heat, what a magnesium fire in the preheating furnace can lead.
Zur Beschickung des Schmelzofens mit vorgewärmten Masseln befindet an dem Deckel des Schmelzofens eine Öffnung, die mit einer Klappe abgedeckt ist. Durch diese Öffnung werden die vorgewärmten Masseln entweder manuell oder automatisch in den Schmelzofen gegeben. Durch die Fallhöhe und das undefinierte Eintreten der Massel in die Schmelze, kommt es zu Magnesiumspritzern und die Schutzgasatmosphäre über der Badeoberfläche wird sehr stark aufgerissen. Daraus resultieren Oxidbildung und Brände auf der Badoberfläche, wodurch die Qualität der Schmelze sinkt.to Charging the furnace with preheated ingots located at the Lid of the melting furnace an opening, which is covered with a flap. Through this opening are the preheated ingots either manually or automatically placed in the furnace. By the drop height and the undefined entry of the ingot into the melt, comes it to magnesium spatters and the inert gas atmosphere over the bath surface is very much torn up. This results in oxide formation and fires on the bath surface, thereby the quality the melt sinks.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorwärmeinrichtung für in einem Schmelzofen zu schmelzende Masseln zu schaffen, die eine sichere Vorwärmung der Masseln (z.B. ≈ 350°C) gestattet und die gegebenenfalls eine automatische Beschickung des Schmelzofens mit Masseln gestattet.Of the Invention is based on the object, a preheating for in a Melting furnace to create melting ingots, which is a safe preheating ingots (e.g., ≈350 ° C) and optionally an automatic feeding of the melting furnace allowed with pigs.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruchs gelöst.These The object is achieved by the Features of the main claim solved.
Dadurch, dass die Vorwärmeinrichtung einen Vorwärmofen aufweist, der eine in einem isolierten Gehäuse angeordnete Förder- und Speichereinrichtung mit Aufnahmen für die Masseln, eine mit einer Tür verschließbare Zuführöffnung, eine mit einer Tür verschließbare Entnahmeöffnung und eine Heizeinrichtung zum Aufheizen des Innenraums des Gehäuses und damit der Masseln durch Konvektion umfasst, wird eine sichere Aufheizung der Masseln ohne Brandgefahr gewährleistet, da keine Strahlungswärme auf die Masseloberfläche übertragen werden kann.Thereby, that the preheating device a preheating oven having a arranged in an insulated housing conveyor and Storage device with receptacles for the pigs, a feed opening which can be closed by a door, a closable with a door removal opening and a heater for heating the interior of the housing and so that the masses by convection includes, is a safe heating Ensures the pigs without risk of fire, there is no radiant heat transferred to the mass surface can be.
Durch die in den Unteransprüchen angegebenen Maßnahmen, sind vorteilhafte Weiterbildungen und Verbesserungen möglich.By in the subclaims specified measures, Advantageous developments and improvements are possible.
Vorteilhaft ist, dass die Heizeinrichtung in einem Bypass-Kanal in Bezug auf die Förder- und Speichereinrichtung angeordnet ist und einen heißen Gasstrom erzeugt, wodurch die Übertragung von Strahlungswärme auf die Masseloberfläche sicher unterbunden wird.Advantageous is that the heater in terms of in a bypass channel the funding and storage means is arranged and a hot gas flow generates, thereby reducing the transmission of radiant heat on the mass surface safely prevented.
Besonders vorteilhaft ist, dass der Vorwärmofen mit einer Beschickungsvorrichtung zum Zuführen der vorgewärmten Massel in das Schmelzebad verbunden ist und die Beschickungsvorrichtung ein schwenkbares, gegen die Umgebung abgedichtetes Schutzgehäuse aufweist. Durch diese Maßnahme kann das Schutzgehäuse in Bezug auf die Schmelzebadoberfläche so geschwenkt werden, dass sie unter einem geeigneten Winkel und ohne wesentliche Aufwirbelung der Badoberfläche mit ihrer kleinsten Fläche eintaucht. Die Schutzgasatmosphäre wird nicht zerstört, da der Ofenraum des Schmelzeofens während des Chargierens geschlossen bleibt, so dass keine Magnesiumspritzer austreten können.Especially It is advantageous that the preheating furnace with a feeder for feeding the preheated pig is connected in the melt bath and the charging device a pivotable, sealed against the environment protective housing has. By this measure can the protective housing be pivoted in relation to the Schmelbadbadoberfläche so that they at a suitable angle and without any significant whirling up the bath surface with their smallest area dips. The protective gas atmosphere will not be destroyed, since the furnace chamber of the melting furnace is closed during charging remains so that no magnesium splashes can escape.
Vorteilhaft ist, dass die Vorwärmeinrichtung eine Zwischenspeichervorrichtung bzw. Separiereinheit von kalten Masseln aufweist, durch die auf einer Palette gestapelte Masseln vereinzelt werden können.Advantageous is that the preheating a Caching device or separating unit of cold pigs has singulated by the stacked on a pallet ingots can be.
Besonders vorteilhaft ist, dass eine Steuereinrich tung vorgesehen ist, die sowohl die Zwischenspeichervorrichtung, den Vorwärmofen und die Beschickungsvorrichtung steuert, so dass eine voll automatische Vorwärmeinrichtung und Masselzuführung abhängig von Parametern des Schmelzofens, beispielsweise Füllstand des Schmelzofens ermöglicht wird.Especially It is advantageous that a Steuereinrich device is provided, the both the intermediate storage device, the preheat oven and the feeder controls, so that a fully automatic preheating and mass feed depends on Parameters of the furnace, such as level of the furnace is made possible.
