Ladle Shroud
Excellent Thermal Shock Resistance
Withstands extreme temperature impacts and frequent thermal cycling during ladle-to-tundish pouring, minimizing cracks, spalling, and ensuring casting continuity.
Effective Secondary Oxidation Prevention
Airtight structure and precision joint design effectively block air ingress, reducing oxidation and inclusion formation, ensuring clean steel.
Superior Corrosion Resistance
Produced from high-purity raw materials to resist chemical erosion from molten steel and slag, significantly extending product service life.
Stable Steel Flow Control
Optimized bore design guarantees uniform flow rate and stream shape, improving tundish performance and final steel quality.
