Description
Verschlußpfropfen für aluminothermische Reaktionstiegel Die Erfindung betrifft einen Verschlußpfropfen für aluminothermische Reaktionstiegel.Closure plugs for aluminothermic reaction crucibles The invention relates to a stopper for aluminothermic reaction crucibles.
Wie aus der Abbildung ersichtlich ist, besteht dieser Reaktionstiegel beispielsweise aus einem Blechbehälter A mit der Bodenögnung E. Der Boden besitzt eine feuerfeste Einlage C. Die Wandungen des Tiegels sind ebenfalls mit feuerfester Masse B ausgekleidet, welche gleichzeitig die ,Einlage C einschließen. Diese Einlage C besitzt eine kegelige Öffnung, in welche der Verschlußpfropfen D eingesetzt ist. Dieser Pfropfen besitzt ebenfalls eine kegelige Öffnung, welche mit einem in feste Form gebrachten aluminothermischen Gemenge E ausgefüllt ist, welches zur Reaktion eine längere, fest bestimmte Zeit als die darüber befindliche Tiegelfüllung G benötigt.As can be seen from the figure, there is this reaction crucible for example from a sheet metal container A with the floor opening E. The floor has a refractory insert C. The walls of the crucible are also refractory Lined mass B, which at the same time enclose the insert C. This deposit C has a conical opening into which the plug D is inserted. This plug also has a conical opening, which is fixed with a Form brought aluminothermic mixture E is filled, which for the reaction a longer, fixed time than the crucible filling G above it requires.
Der PfropfenD ist derart ausgebildet, daß durch eine überrandung ihres oberen Teiles die Einlage C gegen Einwirkung des flüssigen Metalls geschützt ist, was durch Ausfüllung der Lücken zwischen dem Pfropfen D und der Auskleidung B mit feuerfestem Sand H noch ergänzt wird.The plug D is designed in such a way that the insert C is protected against the action of the liquid metal by a border on its upper part, which is supplemented by filling the gaps between the plug D and the lining B with refractory sand H.
Die Wirkungsweise ist folgende: Man setzt in die Einlage C den Abstichpfropfen D, füllt den Ringraum zwischen dem Pfropfen D und der Auskleidung B mit SandH und beschickt den Tiegel mit der Füllung G, deren Reaktionsdauer die übliche ist. Bringt man nun die Füllung G zur Reaktion, so setzt sich das sich bildende, flüssige Metall auf das aluminothermische Gemenge F des Verschlußpfropfens D, dessen Reaktionsdauer eine längere ist als die der Füllung G. Das flüssige Metall bringt das langsam reagierende Gemenge F des Pfropfens D, zur Reaktion, welche nach unten langsam fortschreitet, wobei die sich (neubildende Schlacke im Tiegel aufsteigt. Sobald die Reaktion bis zum unteren Rand der Bohrung des Pfropfens D vorgeschritten ist, fließt das flüssige Metall durch die Öffnung E in die vorbereitete Form.The mode of operation is as follows: The tapping plug is placed in the insert C D, fills the annulus between plug D and liner B with sandH and loads the crucible with the filling G, the reaction time of which is the usual. Brings If the filling G is now used for the reaction, the liquid metal that forms will settle on the aluminothermic mixture F of the stopper D, its reaction time longer than that of the filling G. The liquid metal brings the slowly reacting one Mixture F of the plug D, to the reaction, which progresses slowly downwards, whereby the (newly formed slag rises in the crucible. As soon as the reaction up has progressed to the lower edge of the bore of the plug D, the liquid flows Metal through opening E into the prepared mold.
