Boron nitride ceramic tubes are now being used as core tubes in the continuous casting of hollow metal profiles. These tubes show strong resistance to thermal stress during high-temperature operations. Their performance helps improve the quality and consistency of cast products.

Continuous casting is a key process in metal production. It requires materials that can handle rapid heating and cooling without cracking or deforming. Boron nitride ceramics meet this need well. They maintain structural integrity even under extreme temperature changes.
Manufacturers have tested these ceramic tubes in real production lines. The results show fewer defects in the final products. The tubes also last longer than traditional options. This reduces downtime and maintenance costs.
Boron nitride has low thermal expansion. This means it does not expand or contract much when heated or cooled. That property prevents cracks from forming during casting. It also ensures smoother metal flow through the core tube.
The material is non-wetting to molten metals. This stops metal from sticking to the tube surface. As a result, the casting process runs more smoothly. Surface finish on the hollow profiles also improves.
These ceramic tubes are made using advanced shaping and sintering methods. The process creates a dense, uniform structure. This boosts mechanical strength and thermal stability.
Steel and non-ferrous metal producers are adopting boron nitride core tubes. They see clear benefits in both efficiency and product quality. Demand for these components is growing across the industry.
