Ladle Nozzle Filler Sand Is a Granular Refractory Filling Material Specially. Ladle Nozzle Filler Sand is a granular refractory filling material specially used for nozzles at the bottom of ladles and tundishes. Ladle Nozzle Filler Sand is filled inside ladle seating brick and upper nozzle. It seals the nozzle before tapping and collapses automatically to unblock the steel flow at casting start. The densely packed granular layer withstands the static pressure of molten steel, preventing steel penetration and leakage. It enables automatic casting start and avoids reoxidation of molten steel and production interruption caused by oxygen lancing. This product helps reduce oxygen lancing operations, improve molten steel cleanliness and ensure smooth continuous casting.
