The tundish is a container that mainly undertakes, stores, and redistributes molten steel. It has gradually developed into a metallurgical technology for adjusting the temperature, adjusting trace alloying elements, and improving inclusions and other intermediate materials.

Requirements for Tundish Refractory Materials:

1. The refractoriness is not high, but it is required to resist the erosion of molten steel, steel slag, and slag.
2. It has good thermal shock resistance, requires a low heat transfer coefficient.
3. Good heat preservation performance, no pollution to molten steel.
4. It is easy to build and disassemble.
