The SEN directs molten steel from the tundish into the mold while submerged below the metal surface, controlling flow and preventing oxidation during continuous casting.
Alumina-graphite offers excellent thermal shock resistance, erosion resistance against molten steel, and good mechanical strength at high temperatures.
Proper SEN design with optimized ports/outlets ensures uniform steel flow, minimizes turbulence, reduces inclusions, and improves surface quality of cast steel products.
