摘要:
The invention relates to a method and an apparatus for sealing tuyeres and feed pipes installed in a refractory vessel lining. Seals known per se, in particular prestressable packings, are installed in the gap between the tuyere or feed pipe and the surrounding refractory material in order to avoid backflow of media.
