ABSTRACT:
Metal casting apparatus comprises a casting container having an outlet nozzle in the bottom wall thereof, and an upright stopper within the container having a lower nose end thereto, the stopper being selectively movable between an operative position in which the nose end thereof seats on, to close, the nozzle and an inoperative position in which said nose end is displaced from, to open, the nozzle. The apparatus further comprises a barrier member positioned between the nose end of the stopper and the outlet nozzle and of a refractory material such as ceramic fibre capable of withstanding temperatures associated with pre- and post-heating of the apparatus but which is combustible at temperatures associates with molten metal, the material of the barrier member also being deformable whereby, with the stopper in its operative position, the barrier member conforms with the shape of the nozzle and the nose end of the stopper.
