The tundish impact plate plays a critical role in steel quality by regulating steel flow, reducing turbulence and preventing molten steel from being revealed to the air. The common materials for tundish impact plates are zirconia, alumina, magnesia and some composite materials. In tundish, the impact plate’s size and thickness also depend on the tundish’s size and the molten metal’s volume. Their primary materials are alumina, zirconia, and carbon-containing composites due to their high melting points and resistance to thermal shock.
Tundish impact plates must be maintained to function effectively and reduce costs. Regular visual inspection, focusing on identifying cracks, deformities, or signs of excessive wear, should be done. Quick replacement of these plates upon identifying any defects prevents potential damage to downstream components and ensures the continual quality of steel products.

Tundish Impact Plates Application:
A tundish is a special type of ladle that serves as a reservoir for molten steel before it is poured into molds during the casting process, where the tundish impact plates come into play. Tundish impact plates are located at the bottom of the tundish. They absorb the energy of the incoming molten steel and help spread it evenly across the mold’s cross-section. They are usually made from alumina, zirconia, and silica compounds. The demand for steel all over the world has made the impact plates indispensable when manufacturing steel.
The primary use of tundish impact plates is in steel production industries around the world. The steel production industry mostly uses the tundish dam to absorb the impact of molten steel that flows from the ladle into the mold. However, several industries worldwide use tundish impact plates directly or indirectly.
