Tundish Nozzle
The tundish nozzle is a critical refractory component in the continuous casting process. It is mainly used to regulate the flow rate of molten steel and control its entry into the mold. As a core component in the steel production process, the quality of the nozzle directly affects the continuous casting efficiency, the quality of the ingot, and the production cost. Therefore, choosing a high-quality tundish nozzle is crucial to optimizing the flow of molten steel, improving the quality of the ingot, and reducing the consumption of refractory materials.
Our company specializes in the production of high-performance tundish nozzles, including hydraulic quick-change nozzles, metering nozzles, manual quick-change nozzles, outlet nozzles, and other product types. Our nozzles are made of high-quality zirconium refractory materials, which are resistant to corrosion, and erosion and have long service life. They are widely used in large steel companies at home and abroad.

Tundish Nozzle Composition
Different types of nozzles have different material formulas to meet different continuous casting needs. The following are several common nozzle compositions:

Nozzle Type | Main Components | Characteristics |
---|---|---|
Hydraulic Quick-Change Nozzle | Zirconia + Silicon Carbide | Suitable for general continuous casting needs, easy operation, and cost-effective. |
Metering Nozzle | High-Purity Zirconia (ZrO₂) | Suitable for general continuous casting needs, easy operation, and cost-effective. |
Manual Quick-Change Nozzle | Zirconia + Corundum | Suitable for general continuous casting needs, easy operation, cost-effective. |
Tundish Nozzle | Zircon Mullite + Magnesia | Suitable for various steel grades, including carbon steel and stainless steel. |
Our company uses high-purity raw materials and improves the nozzle’s wear and corrosion resistance through precise composition optimization to ensure its stability in a high-temperature molten steel environment.
Tundish Nozzle Material
The refractory material of the nozzle directly determines its erosion resistance, thermal shock stability, and durability. The tundish nozzles we produce are mainly made of high-performance zirconia-based materials, and their main features include:

High erosion resistance
Zirconium materials can effectively resist the erosion of molten steel and slag, and extend the service life.

Excellent thermal shock stability
It can withstand extreme temperature changes, reducing the risk of cracking and spalling.

High strength erosion resistance
Ensure that the nozzle remains stable in shape under high temperature and high flow rate conditions.

Chemical stability
Reduce impurity penetration, ensure the purity of molten steel, and improve the quality of ingots.

In addition, we strictly control the purity of raw materials during the production process and use advanced isostatic pressing and high-temperature sintering technology to ensure the nozzle’s density and durability.
