Nozzle Filling Compound (NFC) is a specialised granular refractory material used in ladle or tundish sliding gates. It prevents skulling, sintering, and nozzle blockage — ensuring a smooth, uninterrupted, and consistent flow of molten metal during continuous casting operations. Available in Silica, Mixed Refractory, Chromite, and Zircon bases for different temperatures and steel grades.
Available Bases
The most common and economical compound, offering reliable free-opening performance for ladles with standard operating temperatures up to 1650 °C.
A customised blend engineered to specific plant practices, balancing cost, optimal flowability, and temperature resistance for varied operational requirements.
High-density compound for higher-temperature applications, recommended for mild steel. Excellent sintering resistance ensures a high free-opening rate under intense heat.
A premium, high-refractory formulation for secondary steelmaking with long holding times. Withstands extreme heat and extended molten-metal exposure without fusing.
