Abstract (en)
[origin: WO9504621A1] Method and device for opening the outlet of a molten metal handling vessel, comprising a valve (6) having relatively moveable valve parts (7, 9 and 8, 11) and a frangible tube (13) through which gas can be passed, the tube (13) extending through the valve parts (7, 9 and 8, 11) into the outlet (5a) of the vessel, whereby opening the valve (6) by relative movement of the valve parts (9, 11) breaks the tube so that it does not obstruct opening, the end of the tube (13) having a cup-shaped seating portion (13a) to mate with a similarly-shaped recess in or adjacent the valve (6).
