摘要：
The multi-nozzle tuyeres currently used in oxygen-blown converters are fitted with pure copper tips made by forging and welding. These tips rapidly fail because of leakage at the welds. The proposed modification, in which the tip is integral with the nozzle, reduces the total number of components per tuyere from six to two, the tip itself and the cup, and both are made from pure copper. A batch of oxygen tuyere heads with the tips has been tested in the oxygen-converter shop at the Novo-Lipetsk Iron and Steel Works, for blowing 160 tonne converters. They lasted several times as long as the ordinary forged-welded tips and alternative type cast in expandable moulds.
