Boron Nitride Break Rings
Boron Nitride Break Rings for Continuous Casting.
Boron nitride with high chemical resistance against a vast majority of molten metals, combined with excellent thermal shock resistance makes it ideal for various molten metal contact applications. Additionally, due to the material’s strong high-temperature strength, moderate density, and big infiltration angle with molten steel, it exhibits good resistance to molten steel erosion and abrasion, extending the break ring’s service life significantly.
The ceramic break ring comes into contact with both the melt and the solidified alloy, and must satisfy correspondingly strict requirements:
Chemical resistance to the solidified metal
Good sliding properties
High thermal shock resistance
Defined thermal conductivity
High wear resistance
