Abstract (en)

[origin: WO8804209A1] A stopper (6) secured to the lower end of a stopper rod has a faucet (13) with a radial throttle opening (14). A conoidal shut-off face (16) is provided in the stopper (6), above the throttle opening (14). The annular surface of the stopper (13), which penetrates into the outlet bore, provides an additional seal. The stopper (6) can be turned, thus influencing the direction of flow of the outflowing molten mass. The flow can thus be regulated and a high shut-off safety is obtained. Turbulences in the molten mass are further avoided, thus preventing slag from being entrained.
