China Manufacturer High Temperature Resistance Good Fire Resistance Zircon Bricks For Glass Kiln
Zircon fire brick is a kind of shaped refractory brick, zirconia bricks are manufactured with stable zircon sand and over 64% zircon content. zircon brick belongs to acid refractory material with various properties of high mechanical strength, good thermal shock resistance, high refractoriness under load, strong erosion resistance and high density and etc. zircon refractory brick can be widely used in glass furnace, Ladle, pure steel furnace, non-ferrous metal smelting furnace and so on.
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
.Great creep resistance,
.High density,
.High refractoriness under load,
.Excellent thermal shock resistance,
.Good corrosion resistance,
.High mechanical strength.
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.
