Our premium Tundish Dry Vibrating Material is engineered for high-performance continuous casting applications in the ferroalloy and steel smelting industry. Designed to optimize the interface between the permanent lining and the tundish shell, this advanced refractory solution significantly reduces labor intensity through its simple construction and high-efficiency application process.
By integrating superior thermal efficiency and exceptional erosion resistance, our vibrating material ensures a prolonged continuous casting lifespan exceeding 35 hours. It effectively minimizes the tundish slagging rate, thereby purifying molten steel and enhancing the overall quality and consistency of the continuous casting billets.

Frequently Asked Questions
Q: What is the recommended gap for installing the dry vibrating material?
A working gap of 5-12cm should be left between the permanent lining and the tire membrane to allow for proper material flow and density.
Q: How do I avoid junction accidents during the first pour?
It is recommended to appropriately increase the temperature of the molten steel during the first furnace pour to ensure a smooth transition.
Q: Why is it important not to cool the cladding wall after baking?
Cooling the wall after it has been baked red can cause a loose cladding structure, which negatively affects the stability and service life of the tundish.
Q: What are the primary differences between Magnesia and Magnesium Siliceous versions?
The Magnesia version has a higher MgO content (≥75%), while the Magnesium Siliceous version contains ≥60% MgO and ≥20% SiO2, catering to different chemical requirements.
Q: How does this material improve the quality of continuous casting billets?
By maintaining a low tundish slagging rate, the material prevents impurities from entering the molten steel, resulting in cleaner and higher-quality billets.
Q: What is the typical baking sequence for the dry vibrating material?
First, bake on medium-low heat for 1 hour, then increase to high heat until baked red before pouring steel.
