The continuous casting process is a marvel of industrial efficiency, transforming molten steel into various shapes at an impressive rate. But behind the scenes, a crucial yet often unheralded player ensures smooth operation and steel quality: the Submerged Entry Nozzle (SEN).

What is a Submerged Entry Nozzle (SEN)?

A Submerged Entry Nozzle (SEN) is a refractory tube strategically positioned within the continuous casting process. As its name suggests, the SEN is submerged below the molten steel bath within the tundish, a holding vessel that feeds the casting mold. The SEN plays a vital role in:

• Delivering Molten Steel: The SEN acts as a controlled conduit, guiding the molten steel from the tundish into the casting mold.
• Steel Quality: The SEN helps to maintain a clean steel stream by preventing reoxidation of the molten metal during transfer.
• Flow Control: The SEN design allows for optimized flow rate and distribution of molten steel within the mold, influencing the final quality of the cast product.

Benefits of Submerged Entry Nozzles (SEN):

• Improved Steel Quality: By preventing reoxidation and ensuring a clean steel stream, the SEN contributes to the production of high-quality steel with minimal defects.
• Enhanced Process Control: The SEN facilitates precise flow rate control and distribution of molten steel, optimizing the casting process for specific product requirements.
• Reduced Operational Costs: The SEN’s role in maintaining steel quality helps to minimize production of off-grade steel, reducing overall costs.
• Improved Safety: By keeping the molten steel submerged during transfer, the SEN contributes to a safer working environment.
