High temperature fire resistance: The Refractory Material Tundish Well Block is made of high temperature refractory material, which can withstand impact and thermal stress in high temperature environment and maintain stable physical and chemical properties. They maintain structural integrity and fire resistance under extreme high temperature conditions, ensuring stable operation of tundish.

Good corrosion resistance: Refractory Material Tundish Well Block have good resistance to chemical corrosion in molten steel. In the acidic or alkaline environment of molten steel, refractory can effectively resist the corrosion of corrosive substances and prolong the service life of tundish well block.

Uniform flow and mixing effect: The design and placement of tundra well blocks promote uniform flow and mixing of molten steel. Through reasonable design of holes and channels, Refractory Material Tundish Well Block can realize uniform distribution and degassing of molten steel and improve the quality and purity of molten steel.

Structural stability: Refractory Material Tundish Well Block have excellent structural stability and are able to stabilize and support the tundish's refractory lining. They can withstand the impact and pressure of molten steel, not easy to damage or shift, to ensure the normal operation of tundra.

Easy maintenance and replacement: Refractory Material Tundish Well Block are typically modular in design, making them easy to maintain and replace. When the well block wears out or needs repair, it can easily replace damaged parts, reducing downtime and maintenance costs and increasing productivity.

 

 

Treatment of molten steel: The Refractory Material Tundish Well Block is used to support and secure the refractory lining inside the tundish to protect the quality of the molten steel. They ensure the uniform flow and mixing of molten steel in the tundish, help remove impurities and bubbles, and improve the purity and uniformity of molten steel.

Temperature control: Refractory Material Tundish Well Block plays the role of temperature control in the process of steel smelting. They can withstand the thermal shock and stress of molten steel stably in high temperature environment, maintain the stable temperature of tundish, and ensure the quality of molten steel and the stability of smelting process.

Molten steel flow optimization: The design and placement of Refractory Material Tundish Well Block optimize the flow path of molten steel to improve the flow efficiency and uniformity of molten steel. The tundish well block can promote the uniform mixing and degassing of molten steel and reduce the non-uniform flow and the generation of inclusions by proper setting of holes and channels.

Refractory lining protection: The Refractory Material Tundish Well Block protects the refractory lining of the tundish. They support and hold the refractory lining to prevent damage or displacement, and withstand the impact and pressure of molten steel, extending the service life of the refractory lining.

Maintenance and replacement: Tundra well blocks are typically modular in design for easy maintenance and replacement. When the block is worn or damaged, it can be easily replaced, reducing downtime and maintenance costs and increasing productivity.
