Sands & Clays
Ladle Nozzle Filler Sand
Free-flowing filler that keeps the ladle nozzle sealed while the heat is treated, then runs out on its own when the gate opens. Its whole value lies in that moment: a sand that sinters into a crust forces oxygen lancing, which costs time, damages the nozzle and contaminates the steel.
