Construction of a modernized submersible nozzle is developed with an efficient working surface. New submersible nozzles, installed in CBCM crystallizers, make it possible to reduce steel turbulence and flow rate, and to reduce eddy formation at the level of the metal meniscus. Due to this particles of the slag-forming mixture cover the metal meniscus, and are not drawn into a slab. This provides efficient formation of steel flow into the crystallizer and creates conditions for improved metal quality.
