In the precision chain of modern steel smelting, the Tundish Nozzle plays a pivotal role. As the final passage for molten steel flowing from the tundish to the mold, it acts not only as a valve controlling flow rate but also as the “throat” component determining the purity and quality of the final steel product. We understand that in the pursuit of “zero-defect” steel today, the stability of a high-performance nozzle is critical to the continuous casting process.

The Core Function of Tundish Nozzles

The tundish serves as the final metallurgical vessel before solidification, and the nozzle is its precision outlet. Our nozzle products are specifically designed for clean steel production, aiming to optimize molten steel flow characteristics, prevent secondary oxidation, and effectively block non-metallic inclusions. Through precise flow channel design, we assist metallurgical enterprises in bridging the gap from simple “manufacturing” to high-quality “creation.”

Materials and Craftsmanship: The Pursuit of Excellence

Facing the scouring and thermal shock of high-temperature molten steel, ordinary materials often fall short. We employ advanced powder metallurgy and injection molding technologies to create special nozzles with exceptional performance.

• High Temperature Resistance & Thermal Shock Resistance: Our nozzles maintain structural integrity in extreme high-temperature environments, effectively resisting thermal shock and preventing cracking.
• Superior Wear & Erosion Resistance:contrapose the high-speed flow of molten steel, the materials we select possess extreme hardness and anti-cavitation capabilities, significantly extending service life and reducing replacement frequency.
• Precision Flow Channel Design: Whether straight-hole or Laval-type, our flow channels are machined with extreme precision to ensure a stable molten steel flow field, avoiding slag entrapment caused by turbulence.

Why Choose Our Tundish Nozzles?

In the continuous casting process, nozzle stability is directly linked to production efficiency and cost.

• Enhanced Steel Purity: Superior refractory performance reduces contamination from the nozzle itself, guaranteeing molten steel cleanliness.
• Long Life & High Stability: During long-cycle continuous casting operations, our nozzles maintain dimensional stability, resisting expansion or clogging to achieve “zero-failure” operation.
• Customized Solutions: Based on different steel grades (such as aluminum-killed steel, low-carbon steel) and continuous caster models, we provide customized material and shape designs.

Applications

Our Tundish Nozzle products are widely used in continuous casting production lines across major iron and steel enterprises. They perform exceptionally well, particularly in the production of high-end steel grades with stringent quality requirements, such as automotive sheets, pipeline steel, and silicon steel.
