Precisely engineered ports minimize turbulence, distribute molten steel evenly, and reduce surface and internal defects.

Airtight design and oxidation-resistant materials prevent nitrogen pickup and oxidation, ensuring superior steel cleanliness.

Advanced refractory materials extend service life and ensure reliability under harsh thermal and chemical conditions.

Controls mold level fluctuations and improves solidification uniformity, enhancing slab surface quality and consistency.
