Abstract

Un tapón de purga 110 que contiene un material refractario está configurado para insertarse en la base de una cuchara con el fin de introducir gas de purga a través del metal fundido en la cuchara. El tapón de purga aloja una cámara de retención 120 para alojar el contenido de plomo fundido de aleaciones de acero fundido que contienen plomo que se lixivia o infiltra en el tapón de purga. El tubo de suministro de gas de purga 38 está provisto de una porción que se proyecta en la cámara de retención 120, por medio de lo cual se impide que el contenido de plomo de aleaciones de acero fundido que contienen plomo ingrese y bloquee el tubo de suministro de gas de purga 38.A purge plug 110 containing a refractory material is configured to be inserted into the base of a spoon in order to introduce purge gas through the molten metal in the spoon. The purge plug houses a retention chamber 120 to accommodate the molten lead content of molten steel alloys containing lead that is leached or infiltrates the purge plug. The purge gas supply tube 38 is provided with a portion that projects into the holding chamber 120, whereby the lead content of molten steel alloys containing lead is prevented from entering and blocking the purge gas supply 38.
