Abstract

The taphole plug gun for metallurgical furnace, comprises a pressure cylinder (2), which is suited for the reception of clay masses and has a lockable filling opening (3) for the mass and a compaction ram for pressing out the clay mass from a mouthpiece of the pressure cylinder pressed against the taphole of the furnace, and a pivotable safety flap (4) for locking the filling opening of the pressure cylinder for the clay mass. The safety flap comprises a stop (8) for the compaction ram, where the stop is swiveled during opening the flap for braking unintentional forward stroke of the ram. The taphole plug gun for metallurgical furnace, comprises a pressure cylinder (2), which is suited for the reception of clay masses and has a lockable filling opening (3) for the clay mass and a compaction ram for pressing out the clay mass from a mouthpiece of the pressure cylinder pressed against the taphole of the furnace, and a pivotable safety flap (4) for locking the filling opening of the pressure cylinder for the clay mass. The safety flap comprises a stop (8) for the compaction ram, where the stop is swiveled during opening the flap for braking an unintentional forward stroke of the compaction ram for pre-compacting and ejection of the clay mass in the cylinder chamber (9) of the pressure cylinder and is swung out during closing the flap from the cylinder chamber. A roller segment is directed towards outside in the locking position of the safety flap towards outside on one of the long sides of the safety flap that is arched corresponding to the cover of the pressure cylinder and that interferes in the locking position in the filling opening of the pressure cylinder for the clay mass in positive-locking manner. The roller segment is pivoted in open position of the safety flap in the cylinder chamber of the pressure cylinder and forms the stop for the compaction ram. The roller segment comprises a bearing bore for the swiveling axis of the safety clap parallel to middle axis of the pressure cylinder directed for the clay mass. The bearing bore is arranged in clevis at the cover of the pressure cylinder. A handle is arranged in the area of the other long side of the safety flap directed parallel to the middle axis of the pressure cylinder and a hook gripping to the handle is arranged for locking the safety flap in its locking position.

Description

Die Erfindung betrifft eine Stichlochstopfkanone für metallurgische Öfen, mit einem Druckzylinder zur Aufnahme der Stopfmasse, der eine verschließbare Einfüllöffnung für die Stopfmasse aufweist, sowie mit einem Stopfkolben zum Herauspressen der Stopfmasse aus einem gegen das Stichloch eines Ofens angepressten Mundstück des Druckzylinders.The invention relates to a Stichlochstopfkanone for metallurgical furnaces, with a pressure cylinder for receiving the stuffing mass, which has a closable filling opening for the stuffing mass, and with a stuffing plunger for squeezing the stuffing mass of a pressed against the needle hole of a furnace mouthpiece of the impression cylinder.

In der DE 30 07 072 C2 beschriebene Stichlochstopfkanonen dieser Art finden zum Schließen der Abstichöffnungen von Reduktions- oder Schmelzöfen, z.B. Hochöfen zur Roheisengewinnung und Niederschachtöfen zur Erschmelzung von Nichteisenmetallen, Ferrolegierungen usw. Verwendung. Beim Stopfarbeitsgang wird die Stopfkanone mittels einer Schwenkvorrichtung mit einer großen Kraft gegen die Ofenbrust gepresst, wobei die Anpresskraft der Stopfkanone so lange aufrechterhalten wird, bis die durch die Stopfkanone in die Stichlochöffnung des Ofens eingepresste elastische Stopfmasse erhärtet ist.In the DE 30 07 072 C2 described Stichlochstopfkanonen find this kind for closing the tapholes of reduction or smelting furnaces, eg blast furnaces for pig iron production and low shaft furnaces for the melting of non-ferrous metals, ferroalloys, etc. Use. In Stopfarbeitsgang the Stopfkanone is pressed by means of a pivoting device with a large force against the furnace breast, wherein the pressing force of the Stopfkanone is maintained until the stuffed by the Stopfkanone in the tap hole opening of the furnace elastic stuffing compound is hardened.

Bei den bekannten Stichlochstopfkanonen besteht während des manuellen Einfüllens der Stopfmasse in die Zylinderkammer des Druckzylinders die Gefahr, dass durch eine Fehlbedienung des Schmelzers oder eines Arbeitskollegens der Stopfkolben einen unbeabsichtigten Vorwärtshub in Richtung auf das Mundstück des Druckzylinders zum Vorverdichten und Ausstoßen der Stopfmasse ausführt und dadurch der Schmelzer schwere Hand- und Armverletzungen erleiden könnte.In the known Stichlochstopfkanonen during manual filling of the stuffing material in the cylinder chamber of the printing cylinder the risk that performs an unintentional forward stroke towards the mouthpiece of the printing cylinder for pre-compression and ejection of the stuffing mass by incorrect operation of the smelter or a colleague Stopfkolben and thereby the Schmelzer could suffer severe hand and arm injuries.

Der Erfindung liegt die Aufgabe zugrunde, die Betriebssicherheit der gattungsgemäßen Stichlochstopfkanone zu verbessern.The invention has for its object to improve the reliability of the generic Stichlochstopfkanone.
