Zirconia Bricks Application

According to the better physicochemical properties of Zirconia Refractory Brick, it is mostly used in glass furnace, Ladle, pure steel furnace, non-ferrous metal smelting furnace and so on. Such as the follows:

  1. Glass melting furnace.
  2. Ladle lining in the metallurgical industry.
  3. Areas of crown, burner, thermal couple, peep hole, and secondary layer of melter bottom and back lining.
  4. Areas of glass tank, such as paving part and secondary layer of paving bottom, back lining, wall and bottom of fore hearth, flowing spout and spinning portion and melter.
  5. Upper area of flame space or frequent thermal shock position.
  6. Lining of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, ceramic glass, lead glass, and other technical glass melting furnace.
