Tundish Metering Nozzle

/ladle

Manufactured from high-purity materials with optimized formulations to resist molten steel erosion and scouring, extending nozzle lifespan.

Maintains structural integrity under prolonged high-temperature exposure, preventing deformation and ensuring stable operation.

Precisely regulates molten steel flow, minimizing turbulence and inclusions to ensure consistent casting and superior steel quality.

Special production processes enhance thermal shock resistance, preventing cracking and ensuring safety during continuous casting operations.
