Our Products
Product Features
Stable Flow Control
The slide plate holes are centered for smooth, controlled movement. This lets you adjust the molten steel flow continuously during casting, keeping the pulling speed steady and consistent.
High Temperature & Erosion Resistance
Made from high-density refractory materials, with options for high-alumina or zirconia-reinforced grades. It stands up to high heat, molten steel, and inclusion erosion without wearing down.
Excellent Sealing Performance
The plate sits tight against the nozzle seat, greatly reducing the risk of steel leakage or seepage. It works reliably even for long continuous casting cycles.
Easy Installation
Standard dimensions and smooth, precision-cut holes make it directly compatible with most existing ladle sliding mechanisms. No extra work needed to fit it in.
Application Scenarios
This Tundish Slide Gate Nozzle is widely used in the following continuous casting operations:
- Continuous casting lines for square billets, slab billets, and round billets
- Continuous casting of plain carbon steel, low-to-medium alloy steel, and stainless steel
- Ladle systems requiring precise flow control and reduced molten steel fluctuations
- High-speed pulling or extended continuous pouring operations
Usage Advantages
Usage Advantages
In actual production, this type of Tundish Slide Gate Nozzle effectively coordinates with the sliding mechanism to ensure smooth molten steel pouring initiation and reliable shut-off. Compared to traditional flow control methods, the sliding nozzle offers superior sensitivity and stability in flow adjustment. This helps reduce surface defect rates in cast slabs and enhances the overall stability of continuous casting operations.
FAQ
Q: What is a tundish slide gate nozzle used for?
A: It's a key refractory component in continuous casting, installed in the tundish to control molten steel flow to the mold. It allows smooth adjustment of flow rates and keeps the casting process stable.
Q: How does it control molten steel flow?
A: The sliding plate with a precision-machined hole moves against the fixed nozzle. By adjusting the alignment of the two holes, you can change the opening size and fine-tune the flow rate to match your pulling speed.
Q: What materials are these nozzles made of?
A: We use high-density refractory materials, with options of high-alumina or zirconia-reinforced grades. These materials offer excellent heat and erosion resistance for a long service life.
Q: Can it prevent steel leakage during long pours?
A: The tight fit between the slide plate and nozzle seat creates a reliable seal, greatly reducing the risk of leakage or seepage even in long continuous casting cycles.
Q: Will it fit my existing tundish system?
A: Our standard models have common dimensions and smooth through-holes, so they work with most existing ladle/tundish sliding mechanisms. Customization is also available for special requirements.
Q: What steel grades is it suitable for?
A: It works well with carbon steel, alloy steel, and specialty grades like stainless steel, bearing steel, and tool steel. The zirconia-reinforced version is ideal for high-purity and high-alloy steels.
Q: Do you offer customization?
A: We can adjust dimensions, hole diameters, and materials based on your tundish structure, steel grade, and pulling speed requirements.
