| Abstract: | Through analyzing the mechanism of the jam of immersion type nozzle,put forward changing from outside outfit dividing section type nozzle into inside outfit whole immersion type nozzle.At the same time,optimized the geometry size and material of nozzle.Through the practical application in production,the liquid surface undulation frequency of caster mould reduced by 70%,the defects of non-metal inclusions in steel decreased from 2.91% to 0.5%. |
| Keywords: | immersion type nozzle nozzle blocking mould inclusions |
