Refractory brick zirconia refractory bricks for high temperature furnace

Product Description

Zirconia brick is a refractory product which is mainly made of zirconia.There are two main manufacturing methods: firing method and casting method.There are three types of zirconia crystals: monoclinic, tetragonal and cubic.When the zirconia is heated to about 1100℃, the crystal form changes from monoclinic to tetragonal, accompanied by a volume contraction of 7%, otherwise the volume expands.The cubic form of tetragonal zirconia appears above 2300℃.The densities of the three crystal forms were 5.68g/cm3(monoclinic), 6.10g/cm3(tetragonal) and 6.27g/cm3(cubic), respectively.

1,compact zirconia brick
The isostatic pressing method is used for molding, and its technical index is ZrO2&gt;65%, apparent porosity &lt;2.0%, the volume density is about 4.25g/cm3, erosion occurs when the temperature exceeds 1370℃ in E glass.It is used in the bottom of the melting part of the E glass unit kiln where the temperature of contact glass liquid is slightly lower, the bottom of the transition passage, the forming passage and the flow tank of the forming passage and the supporting brick of the leakage plate, etc.In addition, dense zirconium brick is also used as the backing brick of dense chromium brick.
A new type of dense zirconia brick with coarse-grained structure has been developed by VGT-Dyko in Germany. The internal structure of the brick has been greatly improved, and the thermal and cold resistance of the brick has been improved.Its bulk density is 3.75g/cm3, and its porosity is 17%.This brick is ZS65AR and has good thermal shock resistance. It is most suitable for drawing flow tank and leakage plate supporting brick.
2,Standard zirconium brick
The ZrO2 content of the brick is about 66%, the bulk density is 3.7g/cm3, and the brick has good thermal stability and spalling resistance.It is used in the parapet and back wall of the feeding outlet area where the powder erosion is more serious, the parapet and top cover brick of the furnace observation hole and the flame space of the pass-way and the burner brick.

Highly Durable Zirconium Refractory Bricks for Welding and Heat-Resistant Applications

Zirconia hollow ball products are completely made of zirconia hollow ball, have good high temperature strength and stable pore structure, used in ultra-high temperature equipment in the furnace cover and other parts of the insulation material, such as medium frequency high temperature furnace, carbon black reactor, tungsten furnace, molybdenum furnace, etc..
Zirconia hollow ball brick is a kind of heat insulation refractory product with excellent performance. The highest safe operating temperature is 2200℃. It is used as a high temperature lining material directly contacting flame in metallurgical, petrochemical, electronic and other thermal equipment and has good application effect.
The production method of zirconia hollow ball brick and the production method of alumina hollow ball is the same, but its melting temperature is higher, to reach more than 2700℃, at present, the domestic widely used CaO as stabilizer.The brick is made of zirconia hollow balls (65% ~ 70%) and zirconia fine powder (30% ~ 35%) as raw materials, plus boric acid aqueous solution as binder. After mixing evenly, the brick is formed by pressure vibration molding machine. After drying, the prepared brick is fired at 1700 ~ 1800℃.
The zirconia hollow ball used in the raw material is zirconia as raw material, calcium oxide (or yttrium oxide, magnesium oxide) as stabilizer, after uniform mixing, arc melting into molten liquid, and is made by compressed air injection.Zirconia fine powder is made of zirconia as raw material, calcium oxide (or yttrium oxide, magnesium oxide) as stabilizer, evenly mixed, fused into molten liquid, condensed by crushing and grinding.
