Description
Verfahren zum Betrieb von::Aluminiumschmelzöfen Den Gegenstand vorliegender Erfndung bildet eine Brenneranordnung von Metallschmelzöfen, insbesondere für öfen zum Schmelzen von Aluminium und anderen Leichtmetallen und deren Legierungen. Mit dieser Brenneranordnung ist man in der Lage, die Verbrennung des Gases im Ofen, also die Führung der Flamme stufen- oder kaskadenförmig zu gestalten. Insbesondere kann. man mit der entsprechenden Einstellung der zwei Brennerstufen die höchste Temperatur über der Vorschmelzbrücke erzielen und das dort befindliche Metall schmelzen, während andererseits über dem Metallbad eine sauerstofffreie Atmosphäre geschaffen und jede Überhitzung des geschmolzenen Metalls vermieden wird.Method of operating: aluminum smelting furnaces The subject matter of the present Invention forms a burner arrangement for metal melting furnaces, in particular for furnaces for melting aluminum and other light metals and their alloys. With With this burner arrangement one is able to start the combustion of the gas in the furnace, So to design the guidance of the flame in stages or cascades. In particular can. the highest with the corresponding setting of the two burner levels Reach temperature above the premelting bridge and melt the metal located there, while on the other hand an oxygen-free atmosphere is created above the metal bath and any overheating of the molten metal is avoided.
An sich sind Brenner.anordnungen mit zwei oder mehreren hintereinanderliegenden Luftzuführungsstellen bekannt, neu dagegen: ist es, derartige Brenneranordnuugen in der der Erfindung zugrunde liegenden Weise zum Betrieb von Aluminiumschmelzöfen u. dgl. zu benutzen.Burner arrangements are per se with two or more one behind the other Air supply points are known, but new: it is such burner arrangements in the manner underlying the invention for operating aluminum smelting furnaces and the like.
Die Zeichnung dient zur Erläuterung des Verfahrens nach der Erfindung. Dabei ist a der Generator, b das Metallbad und c die Vorschmelzbrücke. DurchdieÖffnungbeidgelan.gt das Heizgas aus dem Gaserzeuger über das Bad. Bei e wird die für das Gas erforderliche Verbrennungsluft zugeführt, wenn über dem Bad die höchste Temperatur gewünscht wird. Soll hingegen die höchste Temperatur auf der Schmelzbrücke c erreicht werden, so wird die Luftzufuhr bei e geschlossen und bei f um so mehr Luft zugesetzt. Die Verbrennungsluft wird durch ein Schleudergebläse g geliefert und in einem Luftvorwärmer des Ofens durch die abziehenden Rauchgase stark vorgewärmt. Die Regelung der Luft an den Brennern e und f erfolgt dabei durch Ventile oder Schieber lt und i.The drawing serves to explain the method according to the invention. Here a is the generator, b the metal bath and c the premelting bridge. The heating gas from the gas generator passes through the opening on both sides via the bath. At e, the combustion air required for the gas is supplied when the highest temperature above the bath is desired. If, on the other hand, the highest temperature is to be reached on the fusible link c, the air supply is closed at e and all the more air is added at f. The combustion air is supplied by a centrifugal fan g and is strongly preheated in an air preheater of the furnace by the evacuating flue gases. The air at the burners e and f is regulated by valves or slides lt and i.
Je nach der Einstellung dieser Ventile kann man über dem Bad oder auf der VorscUmelzbrücke mit oxydierender oder reduzierender Flamme arbeiten. Für viele Schmelzverfahren, insbesondere bei Leichtmetall und seinen Legierungen, ist das von größter Bedeutung. Man kann gewisse Metalle überhaupt nur bei reduzierender Flamme schmelzen, weil sonst der Abbrand so groß wird, daß ein wirtschaftlicher Betrieb überhaupt nicht mehr möglich ist.Depending on the setting of these valves, you can either over the bath or work on the pre-melting bridge with an oxidizing or reducing flame. For many melting processes, especially with light metals and their alloys that of the utmost importance. Certain metals can only be used with reducing ones Melt the flame, otherwise the burn-up will be so great that an economical one Operation is no longer possible at all.
Bei dem hohen Preis des Leichtmetalles und seiner Legierungen ist aber die Frage des Abbrandes von großer Bedeutung.Given the high price of light metal and its alloys but the question of burnup is of great importance.
