    • A device for sealing a lance (12) in an opening in a container under pressure, in particular a shaft furnace, is described. The device comprises a first casing (46) with an end wall on the shaft furnace side and on the environment side, which are each provided axially with an opening for a lance (12), and a sealing element (14), which is arranged in the first casing (46). The sealing element (14) comprises at least one packing (50) and at least one axially movable annular piston (52), which are arranged coaxially with an axis (24) of the device, the packing (50) being arranged between the piston (52) and one of the end walls of the first casing (46) in the actuating direction of the piston (52). The packing (50) is pressed axially against one of the end walls of the casing (46) by actuation of the piston (52), the packing (50) extending radially and being laid around the lance (12) to form a seal.
    • 描述了用于在压力下的容器中的开口中特别是竖炉密封喷枪(12)的装置。 该装置包括:第一壳体(46),其在竖炉炉侧和环境侧具有端壁,它们分别设置有用于喷枪(12)的开口和密封元件(14),密封元件(14)布置 在第一壳体(46)中。 密封元件(14)包括至少一个密封件(50)和至少一个轴向移动的环形活塞(52),其与所述装置的轴线(24)同轴布置,所述密封件(50)布置在所述活塞 (52)和所述第一壳体(46)的端壁中的一个在所述活塞(52)的致动方向上。 密封件(50)通过活塞(52)的动作被轴向压靠在壳体(46)的一个端壁上,该密封件(50)径向延伸并且围绕喷枪(12)放置以形成密封。
