Zircon corundum block an ƙera shi tare da barga zircon yashi da sama da 64% abun ciki na zircon. Zircon corundum block wuta ana zuba a cikin mold bayan an narke a cikin wutar lantarki narkewa. Tsarin lithofacies ya ƙunshi sassan eutectoid da gilashin corundum da zirconium plagioclase. Zircon corundum refractory block petrographic tsarin an yi shi da eutectoid da gilashin lokaci na corundum da zirconium clinopyroxene. Tubalan zircon corundum suna da fasalulluka na ƙarfin injina mai ƙarfi, juriya mai kyau na thermal shock, babban juriya a ƙarƙashin kaya, juriya mai ƙarfi da haɓaka mai yawa.

Properties na Zirconia Corundum Brick

  • High refractority karkashin kaya,
  • Madalla da thermal shock juriya,
  • Kyakkyawan juriya na lalata,
  • Ƙarfin injina,
  • Babban juriya mai raɗaɗi,
  • Babban yawa.
