How Submerged Entry Nozzles Revolutionize Continuous Casting Efficiency
The Critical Role of Submerged Entry Nozzles in Continuous Casting
Submerged entry nozzles (SEN) are specialized refractory components designed to control the flow of molten metal during continuous casting. Positioned between the tundish and mold, SEN ensures a steady, turbulence-free transfer of liquid steel or glass, significantly reducing defects like inclusions and surface cracks. Their submerged design minimizes oxidation and slag entrapment, which are common challenges in high-temperature casting environments.
Material Innovations for Enhanced Performance
Modern SEN solutions leverage advanced refractory materials such as zirconia-mullite composites and high-purity alumina to withstand extreme thermal and mechanical stresses. These materials offer:
- Superior thermal shock resistance: Critical for handling rapid temperature fluctuations during casting cycles.
- Reduced clogging: Specialized coatings prevent alumina buildup in steel casting applications.
- Extended service life: Dense microstructure resists erosion from molten metal flows.
