摘要：The nozzle assembly fitted into the furnace outlet comprises a hard heat and wear resistant insert with a central opening, which is in line with a passage of the nozzle block, into a recess in the top of which it is mounted, and which stands on the furnace lining above the discharge opening of the furnace. The insert is pref. made from W and the block from B-nitride or graphite. The assembly has a long service life and permits quick replacement of either or both components. It is used in connection with the casting of highly refractory material fibres and threads.
