Nozzle for injecting oxygen from a nozzle head into a pig-iron production aggregate, comprises an insert, which is interchangeably insertable into oxygen channel of the nozzle and is made of refractory material

摘要

The nozzle (4) comprises an insert, which is interchangeably insertable into oxygen channel of the nozzle, is made of refractory material and which covers the surface of the oxygen channel including the outlet edge of the oxygen channel. The pig-iron production aggregate is a melting gasifier. The insert extends itself up to 5-30% of the front area over the front surface of the nozzle, which contains openings of the oxygen channel. An independent claim is included for an insert for a nozzle for injecting oxygen from a nozzle head into a pig-iron production aggregate.
