Abstract

um tampão de purga (110) contendo um material refratário é configurado para ser inserido no fundo de uma concha de fundição para introduzir gás de purga através do aquecimento de um metal fundido na concha de fundição. o tampão de purga aloja uma câmara de retenção (120) para reter o conteúdo de chumbo das ligas de aço fundido contendo chumbo que penetram ou se infiltram no tampão de purga. o tubo de fornecimento de gás de purga (38) é fornecido com uma porção que se projeta para a câmara de retenção (120), desse modo, evitando que o conteúdo de chumbo da liga de aço fundido contendo chumbo entre e bloqueie o tubo de fornecimento de gás de purga (38).a purge plug (110) containing a refractory material is configured to be inserted into the bottom of a casting shell to introduce purge gas by heating a molten metal in the casting shell. the purge plug houses a retention chamber (120) for retaining the lead content of lead-containing cast steel alloys that penetrate or infiltrate the purge plug. the purge gas supply tube (38) is provided with a projecting portion for the retention chamber (120) thereby preventing the lead content of the lead-containing molten steel alloy from entering and blocking the supply tube. purge gas supply (38).
