To protect the nozzle body from thermal degradation and erosion while maintaining consistent flow geometry and preventing metal contamination.
Replacement intervals depend on metal type, temperature, and throughput; typically 50-500 pouring cycles or when dimensional tolerance exceeds ±1.5% of original bore diameter.
No, liners are material-specific due to different chemical interactions; aluminum requires different liners than steel or copper alloys.
