The SEN directs molten steel from the tundish into the mold while submerged, preventing oxidation and controlling flow to ensure uniform solidification.
Common materials include alumina-graphite, zirconia-graphite, and fused silica refractories, each offering different thermal and corrosion properties.
Port angle and number of ports influence flow velocity and pattern in the mold, impacting solidification and surface quality.
Actual dimensions and performance values vary by application; confirming with the manufacturer ensures proper fit and operation.
