Description

Verfahren zum dünnschichtigen Auskleiden mittels Zuführungsrinne beschickter Schleudergußkokillen Es ist bekannt, Schleudergußkokillen, die mittels Zuführungsrinne beschickt werden, mit einer dünnen, aus Graphit, Ferrosilicium oder ähnlichen Stoffen bestehenden Schicht auszukleiden. Die Auskleidungsmasse wird ent= weder flüssig.zugeführt, eingespritzt oder eingestäubt, auch unter Verwendung yon Druckluft.Process for thin-layer lining by means of a feed chute Centrifugal casting molds It is known centrifugal casting molds made by means of a feed channel be charged with a thin one made of graphite, ferrosilicon or similar substances to line the existing layer. The lining compound is either supplied in liquid form, injected or dusted, also using compressed air.

Es ist auch bereits vorgeschlagen worden, neben der Zuführungsrinne für die Schmelze noch eine zweite Rinne anzuordnen, durch welche die Auskleidungsmasse zugeführt werden sollte. Die Ausströmöffnung für die Auskleidungsmasse war dabei hinter der Ausflußöffnung für das Metall vorgesehen.It has also been proposed alongside the feed chute to arrange a second channel for the melt through which the lining compound should be fed. The outflow opening for the lining compound was included provided behind the outlet opening for the metal.

Gemäß der Erfindung wird im Gegensatz hierzu die Auskleidungsmasse durch einen im Boden der Zuführungsrinne ausgesparten Zuführungskanal in die Kokille eingeführt.According to the invention, in contrast, the lining compound through a feed channel recessed in the bottom of the feed channel into the mold introduced.

Es ist zwar bereits bekannt, Zuführungsrinnen mit Kanälen für Kühlluft vorzusehen; das neue Verfahren besteht aber in der Nutzbarmachung solcher oder ähnlicher Kanäle zum Einführen einer Aushleidungsmasse.. Dieses Vorgehen verbindet den Vorteil der Kühlung der Zuführungsrinne mit dem Vorteil geringen Raumbedarfs imlerhalb der engen Kokille bei Zuführung einer Auskleidungsmasse. Weiter wird bei geringem Gesamtgewicht der Rinne infolge des sich ergebenden Profils der Rinnenwandung eine Versteifung der Rinne gegen Biegung erzielt. Infolge der Kühlung und der Versteifung neigt die neue Rinne weniger zum Verziehen.Although it is already known, feed channels with channels for cooling air to provide; the new method consists in making such or similar ones usable Channels for introducing a hollow mass .. This procedure combines the advantage the cooling of the feed channel with the advantage of little space required inside the narrow mold when feeding a lining compound. Next is a low overall weight the channel stiffening due to the resulting profile of the channel wall the gutter achieved against bending. As a result of the cooling and the stiffening, the new channel less warping.

Auf der Zeichnung ist als Ausführungsbeispiel eine Rinne dargestellt, welche die Durchführung des Verfahrens nach der Erfindung ermöglicht. -Abb. z zeigt die Rinne im Längsschnitt, Abb. z im Querschnitt.In the drawing, a channel is shown as an embodiment, which enables the implementation of the method according to the invention. - Fig. z shows the channel in longitudinal section, Fig. z in cross section.

Die Rinne a ist mit Sand b o. dgl. ausgekleidet. Im Boden der Rinne ist der Kanal c ausgespart, durch ,welchen das Auskleidungsmaterial beispielsweise mittels Druckluft hindurchgeleitet wird. Die Wandung des Kanals besteht vorteilhaft mit der Wandung der Rinne aus einem Stück. Das Auskleidungsmaterial strömt durch die Öffnung d zur Kokillenwand, während das Metall durch die Ausflußöffnung e in die Kokille eingeleitet wird.The channel a is lined with sand b or the like. The channel c through which the lining material is passed, for example by means of compressed air, is recessed in the bottom of the channel. The wall of the channel advantageously consists of one piece with the wall of the channel. The lining material flows through the opening d to the mold wall, while the metal is introduced into the mold through the outlet opening e.
