China New Arrival China Magnesia Refractory Bricks - Rongsheng Zircon Refractory Brick For Glass kiln – Rongsheng factory and manufacturers | Rongsheng Detail:
zircon firebrick refers to the refractory brick that contains raw materials of zircon or ZrO2 more than 90%. Besides, there are other refractory bricks that contain zircon, such as the Zr-Al brick, zirconia firebrick can improve the thermal shock resistance; Zr-Cr-Al brick, which improves the refractoriness and anti-corrosion resistance; and Zr-SiC brick that improves slag and wear resistance. zirconia brick various properties of high mechanical strength, good thermal shock resistance, high refractoriness under load, strong erosion resistance and high density.
Properties of Zircon Brick
- Great creep resistance,
- High density,
- High refractoriness under load,
- Excellent thermal shock resistance,
- Good corrosion resistance,
- High mechanical strength.
Zircon Brick Manufacturing Process
Zircon fire block is made from stable zircon sand is a kind of great refractory brick with the zircon content over 64 %. zircon refractory block is acid refractory with the advantages of high mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquid.
