Abstract
The embodiments of the invention relate to a tap hole plug gun for metallurgical furnaces, having a pressure cylinder for receiving the plugging compound, which has a closable filling opening for the plugging compound, and having a plugging piston for pressing the plugging compound out from a mouthpiece of the pressure cylinder pressed against the tap hole of a furnace. The pivotable safety flap for closing the filling opening of the pressure cylinder for the plugging compound is equipped with a stop, which is pivoted into the cylinder chamber of the pressure cylinder upon opening of the flap to decelerate an unintentional forward stroke of the plugging piston for pre-compression and expulsion of the plugging compound, and is pivoted out of the cylinder chamber upon closing of the safety flap.
