Description
In der Zeichnung ist die Anordnung der Düsen dargestellt, mit Hülfe deren man die Oxydation der in dem Ofen bearbeiteten Metalle befördern und reguliren kann.In the drawing, the arrangement of the nozzles is shown, with the help of which you can Can promote and regulate oxidation of the metals worked in the furnace.
Wenn man in Flufs befindliches Rohkupfer, Gufseisen oder ein sonstiges Rohmetall raffmiren will, so mufs man einen Theil dieses Metalls oxydiren, um die mit demselben verbundenen Metalle und Metalloide weiter oxydiren zu können.When you raffmiren raw copper, cast iron or some other raw metal in rivers If so, one must oxidize a part of this metal in order to remove those connected with it To be able to further oxidize metals and metalloids.
Einige derselben entweichen in Gasform, während andere durch die Oxydation verschlackt werden. Diese Schlacken schwimmen auf dem raffmirten Metallbade und verhindern die weitere Oxydation.Some of these escape in gaseous form, while others are slagged through oxidation will. These slags float on the smooth metal bath and prevent further oxidation.
Um dies zu umgehen, bringt man an dem Ofen die in der Zeichnung dargestellte Vorrichtung an.To get around this, the device shown in the drawing is attached to the furnace at.
Es ist M die Arbeitsthür, K ein über den Ofen laufendes festes Luftzuleitimgsrohr mit Gelenk, um welches sich das Rohr / m drehen läfst; m ist ein zweites Gelenk, ari welchem die Düsen«;? sitzen. Die punktirten Linien/;«'72' deuten die Stellung des Luftrohres und der Düsen an, wenn dieselben in die Höhe gehoben sind, um die Arbeit nicht zu hindern; ρ zeigt die Richtung der Luftströme und q die Richtung, in welcher sich die Sohle dreht; r ist eine Schlackenwelle, wie sie durch die starken Luftströme zurückgetrieben wird, um die Oberfläche des Metalles für die Einwirkung des zugeführten Sauerstoffes freizulegen.It is M the work door, K a fixed air supply pipe with a joint running over the furnace, around which the pipe / m can rotate; m is a second joint, ari which the nozzles «; sit. The dotted lines / "72" indicate the position of the air pipe and the nozzles when they are raised so as not to hinder the work; ρ shows the direction of the air currents and q the direction in which the sole rotates; r is a slag wave that is driven back by the strong air currents in order to expose the surface of the metal for the action of the supplied oxygen.
Um den Gebläsewind zuzuleiten, werden die in der Stellung I m' n' befindlichen Düsen mit Hülfe einer Kette und Kettenscheibe niedergelassen und mit Hülfe der Handhabe y in die Oeffnung s eingeschoben.In order to supply the blower wind, the nozzles located in the position I m 'n' are lowered with the aid of a chain and chain pulley and pushed into the opening s with the aid of the handle y .
Die Luft wird unter einem Druck bis zu 3 Atmosphären in einer der Drehung der Sohle entgegengesetzten Richtung eingeblasen und treibt die Schlacken zurück, so dafs die Metalloberfläche frei gelegt wird. Dies geschieht ein- bis zweimal während der Operation, welche auf diese Weise beträchtlich verkürzt wird.The air is under a pressure up to 3 atmospheres in one of the rotation of the sole blown in the opposite direction and drives the slag back, so that the metal surface is exposed. This happens once or twice during the surgery which is on this way is shortened considerably.
