Brief: Discover the ZrO2 Steel Plant Refractories Zirconium Sizing Tundish Nozzle, designed for high-temperature steel melting. This refractory nozzle features zirconia inner cores for exceptional fire resistance, thermal stability, and corrosion resistance. Ideal for continuous and molded casting, it offers long service life and minimal diameter expansion.
Related Product Features:
  • High fire resistance with zirconia inner core (70-95% ZrO2 content).
  • Excellent thermal shock stability (5 cycles at 1100°C water cooling).
  • Corrosion and erosion-resistant for prolonged durability.
  • Minimal diameter expansion ensures consistent performance.
  • Available in Al2O3-C, MgO-C, and spinel-C based bowl parts.
  • Customizable options include ordinary, quick exchangeable, and gas purging nozzles.
  • Wide application in continuous and molded casting processes.
  • Varied service life based on different specifications and ZrO2 grades.
Faqs:
  • What are the key components of the tundish zirconium sizing nozzle?
    The nozzle features an Al2O3-C based main body, with bowl parts available in Al2O3-C, MgO-C, or spinel-C. The inner core is made of zirconia, offering high fire resistance and thermal stability.
  • How does the ZrO2 content affect the nozzle's performance?
    Higher ZrO2 content (up to 95%) enhances fire resistance, bulk density, and reduces apparent porosity, leading to better durability and longer service life in high-temperature steel melting.
  • What types of tundish nozzles does CH Refractories offer?
    CH Refractories provides ordinary, quick exchangeable, and gas purging upper nozzles, tailored to meet diverse steel melting needs with options for different materials and specifications.
