Caster Tip / Spacer / Hard Ear

Caster Tip, Spacer, and Hard Ear are precision refractory components used in aluminum continuous casting and rolling systems. They are designed to regulate molten aluminum flow, control gap settings, and maintain stable casting conditions, ensuring high-quality aluminum foil billets and other aluminum products.

Integrated with nanoscale fiber composite materials and processed with precision equipment, these components achieve accurate dimensional control and consistent performance across repeated casting cycles. Key surfaces are treated with advanced nano-coatings, providing sealed, non-delaminating, and non-stick surfaces that resist aluminum liquid erosion.

The internal structure is optimized with symmetrical flow channels, meeting hydrodynamic requirements for smooth molten aluminum transfer while minimizing turbulence and oxidation. Excellent thermal insulation ensures consistent process parameters in the casting and rolling area, crucial for high-quality billet production.
