Description
Dreiphasen-Lichtbogenofen mit schwenkbaren Elektroden Bei dreiphasigen Liehtbogenöfen mit senkrecht durch den Deckel geführten Elektroden, welche in der Regel ,als. Heroultöfen bezeichnet werden, hat sich. fast -'allgemein eine Bauart durchgesetzt, bei welcher die drei Elektrodenführungen an einer Seite des; Ofens nahe beieinander angeordnet werden. Die. Elektroden hängen dann an drei nahezu parallelen Auslegern, und die Stromzuführung wird an diesen Auslegern entlang., gleichfalls von einer Seite zu dent Ofen bewerkstelligt.Three-phase arc furnace with pivoting electrodes For three-phase Liehtbogenöfen with electrodes led vertically through the lid, which in the Rule, as. Heroultöfen has become known. almost -'generally a type enforced, in which the three electrode guides on one side of the; Furnace be placed close to each other. The. Electrodes are then attached to three almost parallel ones Cantilevers, and the power supply is along these cantilevers., Likewise Done from one side to the dent oven.
Bei dreiphasigen Lichtbogenelektroöfen mit durch den Deckel hindurchtretenden geneigten Elektroden, deren Neigung gegeneinander während des Betriebes verstellf werden kann, und bei denen die Führungs- und Bewegungsteile für die Elektroden an dem Ofengefäß befestigt werden, wurden dagegen bisher die drei Führungsgerüste mit gleichem Abstand voneinander verteilt am Umfange des Ofens angeordnet. Die waagerechte Drehachs:. für die Verstellung der Neigung dieser Führungsgerüste verlief im wesentlichen senkrecht zum Elektrodenausleger.With three-phase electric arc furnaces with penetrating through the cover inclined electrodes, the inclination of which is adjusted against each other during operation can be, and in which the guide and moving parts for the electrodes are attached to the furnace vessel, however, were previously the three guide frames with arranged at the same distance from each other distributed around the circumference of the furnace. The horizontal one Rotary axis: for the adjustment of the inclination of these guide frames essentially ran perpendicular to the electrode arm.
Diese Anordnung hat die Unannehmkchkeit, da.ß die drei Führungen das ganze Ofengefäß von allen Seiten unzugänglich machten, ferner, daß beim Kippen des Ofens die Elektrodenführungen im Weg waren und schließ-Hüh daß die Stromzuführung zu den Elektroden sich schlecht von einer Seite her durchführen ließ.This arrangement has the inconvenience that the three guides do made whole furnace vessels inaccessible from all sides, furthermore that when the Oven the electrode guides were in the way and shut off the power supply to the electrodes could not be passed through from one side.
Um diese Schwierigkeiten zu vermeiden, wird erfindungsgemäß nur eine -einzige Elektrode in der oben beschriebenen Weise angeordnet und die beiden anderen Elektrodenführumgen um eine Achse schwenkbar angeordnet, welche parallel zu dem Elektrodenausleger liegt. Damit ist, wie die Zeichnung zeigt, die Möglichkeit gegeben, alle drei Führungen einseitig nebeneinanderliegend anzuordnen.In order to avoid these difficulties, according to the invention, only one -single electrode arranged in the manner described above and the other two Electrode guides arranged to be pivotable about an axis which is parallel to the Electrode arm lies. As the drawing shows, there is thus the possibility of to arrange all three guides side by side on one side.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung in den Abb. i bis 3 in drei. Ansichten.The drawing shows an embodiment of the invention in Figs. i to 3 in three. Views.
Mit a ist der Ofen bezeichnet; der in bekannter Weise kippbar gelagert werden kann. Durch den. Deckel b dieses Ofens sind um i2o° versetzt gegeneinander drei Elektroden c geneigt in den Ofenraum eingeführt. Die Elektroden e hängen mittels der Fassungen d an Auslegern e bzw. f, welche in bekannter Weise an Führungssäulen g bzw. 1z vermittels eines nicht dargestellten Getriebes auf und ab bewegt werden können.The furnace is denoted by a; which can be tilted in a known manner. Through the. Cover b of this furnace, three electrodes c, offset from one another by 120 °, are inserted into the furnace chamber at an angle. The electrodes e hang by means of the sockets d on brackets e and f, which can be moved up and down in a known manner on guide columns g and 1z by means of a gear (not shown).
Zwecks Verstellung des Neigungswinkels der Elektrode c ist nun die Führungssäule g um :einen waagerechten Zapfen i" meinem am Ofengefäß befestigten Lager h schwenkbar gelagert, und ihre Neigung kann durch die Schraube C verändert werden. Der Zapfen i steht senkrecht zu der Bewegungsebene des Auslegers e. Der Punkt i ist dabei so gewählt, daß beim Schwenken der Führung g bzw. der Elektrode C eine möglichst geringe Wanderungder Elektrodenachse an der Durchtrittsstelle durch den :Deckel b in der Bildebene stattfindet. Die Führungen* der beiden anderen Elektroden sind um den Bolzen m, die ebenfalls in Lagern n am Ofengefäß befestigt sind, in gleicher Weise schwenkbar wie die Führung g. Diese Bolzen m stehen ebenfalls senkrecht zur Bewegungsebene der Elektroden c, jedoch parallel zu dem Ausleger f. Die Verlängerung der Achse des Bolzens m schneidet die Achse der Elektrode c gerade an der Durchtrittsstelle durch das Gewölbe b.To adjust the angle of inclination of the electrode c is now the Guide column around: a horizontal pin attached to the furnace vessel Bearing h is pivoted and its inclination can be changed by means of the screw C. will. The pin i is perpendicular to the plane of movement of the boom e. Of the Point i is chosen so that when pivoting the guide g or the electrode C the least possible migration of the electrode axis at the point of passage den: cover b takes place in the image plane. The guides * of the other two electrodes are around the bolt m, which are also attached to the furnace vessel in bearings n, in pivotable in the same way as the guide g. These bolts m are also vertical to the plane of movement of the electrodes c, but parallel to the boom f. The extension the axis of the bolt m intersects the axis of the electrode c just at the point of passage through the vault b.
Auf diese Weise werden die drei E1ektrodenführungen ähnlich wie bei den bekannten Heroultöfen neuer Bauart an der einen Seite des Ofens zus;amm@engefaßt, und die Stromzuführungskabel o lassen sich bequem nahezu parallel von dieser Seite an den Ofen heranführen.In this way, the three electrode guides become similar to the well-known Heroult ovens of a new design on one side of the oven; amm @ engefasst, and the power supply cables o can be conveniently almost parallel from this side bring them up to the oven.
