Description
Es ist bereits vorgeschlagen worden, die dem aluminogenetischen Eisen zuzusetzenden, ihm die Eigenschaften eines legierten Stahls verleihenden Elemente vor und während der Reaktion als Tiegelabschluß zu verwenden. Zu diesem Zweck hat man den Abstichstift mit einer Schicht dieser Elemente bedeckt. Ein bevorzugtes derartiges Element ist bekanntlich Silicium.It has already been proposed that the aluminogenetic iron to be added Elements giving it the properties of an alloy steel before and during To use the reaction as a crucible seal. The tapping pen is used for this purpose covered with a layer of these elements. A preferred such element is known Silicon.
Die Erfindung besteht darin, daß Silicium in Form von Siliciumcarbid zur Bildung des Tiegelverschlusses verwendet wird. Wird das Siliciumcarbid beispielsweise als Brikett über und in dem Abstichloch angebracht, so vermag es den Ausfluß des Eisens so lange aufzuhalten, als Zeit für die Vollendung der Reaktion im Tiegel erforderlich ist. Alsdann öffnet und entleert sich der 'Tiegel selbsttätig. Dadurch wird der Abstichstift entbehrlich.The invention consists in that silicon in the form of silicon carbide to form the Crucible closure is used. If the silicon carbide is used, for example, as a briquette and placed in the tap hole, it can stop the outflow of iron for so long than the time required for the reaction in the crucible to complete. Then the 'crucible opens and empties automatically. This makes the tapping pin unnecessary.
Damit die Zeitdauer vom Beginn der Reaktion bis zur selbsttätigen Öffnung des Tiegelabstichloches stets gleichbleibend ist, ist es vorteilhaft, die Reaktion des Gemisches stets an ein und derselben Stelle innerhalb des Tiegels einzuleiten, z. B. in der Mitte des Gemisches. Um das zu erreichen, kann man beispielsweise die Zündpille am Ende eines Eisenstabes befestigen, der durch die mittlere Öffnung der Tiegelkappe senkrecht so tief hineingestoßen wird, wie es ein Anschlag zuläßt. "Die Zeichnung zeigt schematisch.eine Ausführungsform der Erfindung. Es bezeichnet : α den Tiegel, b die Abstichöffnung, c ein dünnes Eisenblech, d pulverförmiges Siliciumcarbid, e andere Legierungsbestandteile, / das aluminothermische Gemisch, g Tiegelkappe, h den Zündstabj, / den Anschlag über der Öffnung der Tiegelkappe, k die Zündpille. So that the time from the start of the reaction to the automatic opening of the crucible tap hole is always constant, it is advantageous to always initiate the reaction of the mixture at one and the same point within the crucible, e.g. B. in the middle of the mixture. To achieve this, you can, for example, attach the squib to the end of an iron rod which is pushed in vertically through the middle opening of the crucible cap as deep as a stop allows. The drawing shows schematically an embodiment of the invention. It denotes: α the crucible, b the tapping opening, c a thin sheet of iron, d powdered silicon carbide, e other alloy components, / the aluminothermic mixture, g crucible cap, h the ignition rod, / the stop above the opening of the crucible cap, k the squib.
Es ist bekannt, daß Tiegelabstichloch mit einem Pfropfen zu verschließen^ der aus einem brikettierten aluminothermischen Gemisch besteht, das zur Reaktion eine längere, fest bestimmte Zeit als die darüber befindliche Tiegelfüllung benötigt und erst durch das abgeschiedene Metall der Tiegelfüllung entzündet wird. Bei Beendigung der Reaktion innerhalb des Abstichloches wird letzteres für den Durchfluß des Tiegelinhaltes frei.It is known to close the crucible tap hole with a plug consists of a briquetted aluminothermic mixture, which requires a longer, a fixed time than the crucible filling above it and only through the deposited metal of the crucible filling is ignited. At the end of the reaction inside the tapping hole, the latter is free for the contents of the crucible to flow through.
