Fused Silica Immersion Nozzle with Zirconium Insert

Fused silica immersion nozzleZirconium fixed diameter zirconium inlaid water inlet   In continuous casting production that pursues high lifespan and stability, although pure zirconium nozzles have excellent performance, their manufacturing costs are high. In order to achieve the best balance between key performance and economic benefits, zirconium fixed diameter embedded nozzles have emerged as an innovative engineering technology solution.1. Structural design and core conceptComposite structure: The water outlet is not entirely made of expensive high-purity zirconium material, but adopts a composite design. Its main body is composed of high-strength aluminum carbon or aluminum zirconium carbon materials, providing excellent thermal shock resistance and structural support for the water outlet; In the most critical inner hole working lining (i.e. sizing area), a high-purity zirconia (ZrO ₂) material annular lining or core is precisely embedded.Core concept: This design follows the princ…
