Abstract

DISPOSITIVO PARA MEDIR O CONTEúDO DE GáS EM UM METAL FUNDIDO. A presente invenção refere-se a um dispositivo para medir o conteúdo de gás em um metal fundido, incluindo uma extremidade de imersão tendo um corpo de coleta do gás, uma linha de suprimento do gás abrindo na extremidade de imersão e uma linha de descarga de gás para os gases passando através do corpo de coleta do gás e a invenção consiste em que o corpo de coleta do gás contém materiais, que em contato com o metal fundido não formam produtos de reação líquidos.
