Tundish Well Block is one of the key refractory materials in the continuous casting process. It is mainly used in the outlet area of ​​the tundish to support and fix the nozzle to ensure the stability and controllability of the molten steel flow.
FerrumX has more than 20 years of experience in refractory production. Our Tundish Well Block is made of high-performance refractory materials, such as high aluminum and magnesium carbon. It has excellent high-temperature, corrosion, and thermal shock resistance. It can remain stable for a long time in a high-temperature molten steel environment to ensure efficient steelmaking production.

Scope of application:

• Applicable to all types of steel mills, including small, medium, and large steelmaking enterprises
• Applicable to various tundish continuous casting processes
• Tundish Well Blocks of different specifications and materials can be customized according to customer needs
• Mainly used in the tundish outlet area to fix and support the nozzle to ensure stable flow of molten steel
• Suitable for all steel mills, from small and medium-sized steel mills to large continuous casting production lines
• Adapt to various nozzle systems to ensure the efficiency of the steelmaking process

Product Advantages (Compared to Traditional Products)

FerrumX Tundish Well Block is manufactured with a high-performance formula and advanced technology. It is superior to traditional tundish nozzle block products in terms of refractory performance, structural stability, and service life, bringing more reliable continuous casting protection to steel mills.

Performance Indicator	FerrumX Tundish Well Block	Traditional Tundish Well Block
Refractoriness	≥1790℃, stable under long-term high temperatures	Around 1600℃, prone to softening and deformation
Erosion Resistance	High-density structure, excellent resistance to molten steel	Low density, easily corroded
Thermal Shock Resistance	≥30 thermal cycles, excellent resistance to rapid heating/cooling	Poor thermal shock resistance, prone to cracking and spalling
Service Life	15–30 casting heats	Only 8–12 casting heats
Applicable Steel Plants	Suitable for steel plants of all sizes	More suitable for small-scale plants; less stable
