Custom Zirconia Tundish Nozzle
Custom Zirconia Tundish Nozzle is precision-formed and high-temperature sintered from high-purity zirconia material, offering wear resistance, high-temperature tolerance, corrosion resistance, and extended service life. We accept custom orders based on drawings or samples, suitable for demanding metallurgical applications such as continuous casting and refining.
Products Description
This custom-made zirconia tundish nozzle is a durable component engineered specifically for continuous casting operations in steel mills. Crafted from high-purity zirconia material through precision sintering and machining, its purpose is straightforward: minimize replacements, eliminate failures, and ensure stable casting. Common on-site issues-enlarged inner holes, slag adhesion, explosions, and frequent replacements-this product significantly delays the onset of such troubles.
Product Highlights
Wear Resistance
- Dense inner bore resists enlargement even under prolonged exposure to molten steel and slag erosion, ensuring stable flow and fewer casting defects.
Thermal Shock Resistance
- Optimized sintering and formulation prevent cracking during frequent start-stop cycles, eliminating daily monitoring for potential spalling.
High-Temperature Stability
- Maintains shape near furnace openings and during continuous casting, ensuring consistent assembly positioning.
Smooth Surface, Minimal Slag Adhesion
- Precision-ground or polished inner bore resists slag buildup, enabling quick cleaning and reduced maintenance downtime.
High dimensional accuracy, optimized flow field
- We precisely adjust taper angles, transition sections, and inner curvature to match your process, minimizing turbulence and steel adhesion.
Extended lifespan, lower total cost
- Higher upfront cost but longer service life. Reduced replacements save labor and minimize downtime, delivering long-term value.
Sample testing before bulk production
- We support sample testing first. Proceed with bulk production only after on-site validation, minimizing risk.
Application Scenarios
- Slab/Billet/Round Ingot Continuous Casting Ladle: As the core component for metering and flow guidance, it ensures uniform molten steel flow into the mold, reducing cracks and slag inclusions.
- High-Pace Continuous Casting Lines: For multi-furnace continuous casting and round-the-clock production lines requiring infrequent nozzle replacement, we deliver.
- High-temperature steels like stainless and alloy steels: These molten steels feature high temperatures and active slag systems where standard components often fail. Our solutions are better suited.
- Applications with high impurity or slag content: Resists clogging even in heavy slag conditions, reducing on-site cleanup workload.
- Retrofitting legacy equipment: Complex interfaces on older continuous casting lines? We provide custom replacements without structural modifications.
- Pilot or R&D lines: Small-batch, rapid prototyping facilitates process tuning and comparison.
- Overseas or extreme environments: Material and process adjustments tailored to site conditions, adapting to diverse standards and climates.
- Emergency spares: Durable backup components ready for critical moments, preventing unexpected production halts.
