ABSTRACT:
An upwardly open vessel which, in use, contains a metallurgical melt, the upwardly open vessel having an upper rim. A suction hood having a lower rim sized and shaped so that, in use, the lower rim of the suction hood opposes the upper rim of the upwardly open vessel but is spaced therefrom to permit ambient air to enter through an annular gap therebetween. A covering bell having a lower rim is mounted on the underside of the suction hood in position so that, in use, the lower rim of the covering bell isolates a portion of a slag cover on a metallurgical melt in the upwardly open vessel. Corresponding openings are provided in the suction hood and the covering bell to permit access to the isolated portion of the slag cover by an externally operated probe or the like.
