ABSTRACT:
An apparatus for screening a stream of molten metal has a bellows. An annular distribution chamber for protective gas to be blown into an area traversed by the stream of molten metal is provided inside the bellows. That annular chamber is inwardly delimited by a flexible screening shroud of heat-resistant, gas-permeable material encompassing the area traversed by the stream of molten metal and being inwardly spaced from the bellows. Corresponding ends of the bellows and shroud are gas-tightly interconnected. The screening shroud surrounding the pouring stream at a distance protects the bellows from metal splashes and screen it also from heat that is radiating from the pouring stream.
