Ladle Shroud
High Purity, High Stability, Long Service Life, Ensuring Steel Quality
Ladle shroud
Excellent Thermal Shock Resistance
Withstands the extreme temperature impact and thermal cycling when molten steel flows from the ladle, minimizing cracks and spalling, and ensuring continuous casting stability.
Outstanding Corrosion Resistance
Formulated with high-purity raw materials to effectively resist chemical erosion from molten steel and slag, extending ladle shroud service life.
Efficient Prevention of Secondary Oxidation
Optimized airtight structure and precision joint design effectively block air intrusion, reducing steel oxidation and inclusions.
Stable Steel Flow Control
Precisely engineered bore design ensures consistent steel flow rate and stream shape, improving tundish casting uniformity and billet quality.
