Abstract

Apparatus for removing the impurities present in gaseous and solid form in a liquid product such as liquid metal contained in a conveying ladle. The apparatus is of the type comprising a rotor which essentially includes a rotary shaft (7) carrying at its free end liable to be immersed in the said liquid product a member (8) forming a stirring head, provided with an internal chamber (14) connected through an axial channel (15) made in the said rotary shaft (7) to a source of an inert gas and communicating with the outside by means of passages through the walls of the said head. The apparatus is characterised in that the member forming a head (8) is made of a porous material, such as porous graphite, the walls of the said head exhibiting a porous structure permeable to the gas present in the said chamber (14) inside the head. The invention can be employed for ladles for conveying liquid metals. <IMAGE>
