What is Nozzle Filling Compound ?

Nozzle filling compound is a refractory material used in the construction and repair of tundish nozzles in the steelmaking industry. Tundish nozzles are critical components in the continuous casting process, where molten steel is passed from the ladle through the tundish and into the mold to create continuous cast products. The nozzle filling compound is designed to fill and seal the nozzles to prevent steel leakage and ensure a controlled and smooth flow of molten steel.

The composition of nozzle filling compounds can vary, but they typically include refractory aggregates, binders, and additives that provide the necessary properties for resisting high temperatures, thermal shocks, and the erosive effects of molten steel. The compound is applied to the nozzle area to create a protective lining that withstands the harsh conditions of the steelmaking process.
