Description
High Temperature Resistance Dense Zircon Refractory Blocks
The Description:
Zircon bricks contain 67.23% zirconia and 32.77% silica. Tetragonal crystal system, generally in quadrangular column type. Mohs hardness 7.5, 20 ~ 1000ºC thermal expansion coefficient of 4.2×10-6/ºC. The melting point is 2430ºC. Volume relative density 3.60 ~ 4.3g/cm3. The apparent porosity is 0% ~ 18%. Load softening temperature >1550ºC. It was prepared by semi-dry suppression and forging and firing at 1600ºC. Suitable for sizing water orifice for lining and continuous steel injection in steel barrels

Product feature:
High Temperature Resistance Dense Zircon Refractory Blocks made by isotatic pressing technology,are characterized by resistance to high temperature,good thermal shock resistance,glass liquid erosion resistance etc.They are mainly used for bottom blocks,superstructures blocks,tuckstones,transtion bricks,flow blocks,peepphole blocks etc.In non-alkali glass,borosilicate glass.
The application:
The brick has high molecular structure density, high volume relative density, large bulk weight, high impact toughness at room temperature and high temperature, good thermal shock reliability, small refiring and high temperature stress relaxation, and has very high organic chemical reliability and resistance to alkali corrosion.
