    • 专利摘要:
    A gate valve for an outlet, in particular an extended outlet, of a vessel containing molten metal comprises an immovable, refractory gate-valve part (3) with inflow and outflow openings and a refractory gate-valve part (13) which can be moved sealingly relative to the immovable gate-valve part and has a connecting channel for connecting the inflow and outflow openings in the open position of the gate valve. In order to avoid penetration openings for the connecting channel, the movable gate-valve part (13) has as a connecting channel at least one recess (15) extending on the circumferential surface (14) of the movable gate-valve part (13). …<IMAGE>…
