Silica brick is made of quartz stone material, the content of SiO2 is above 96%,it has good resistance to acid slag and good heat conductivity.

Introduction of silica refractory brick :

Silica brick is made of quartz stone material, the content of SiO2 is above 96%,it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1680°C.

SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk. So there is a close contact between the changes of SiO2 crystals and the produce ,performance and usage of silica bricks. During the heating, there will be changes of the bulk ,and cristobalite changes most, then quartz, phosphorus quartz is the slowest of all and it also has good heatconductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.

Feature of silica refractory brick :

1.Good thermal stability, low thermal conductivity, good insulation performance.

2. Low bulk density, good integrity, high mechanical strength.

3. Good thermal shock stability, good resistance to abrasion and corrosion.

4. Good volume stability at high temperature.

5. Low water absorption rate, low creeping rate.

6. Natural clay products, could be shaped freely, non-radioactive and environmentally friendly.

2.Good acid erosion resistance.

3. High softening point with temperature.

4. No shrink in burn repeatedly.

5.Temperature of refractoriness under load is above 1680º C

Application of silica refractory brick :

1.Coke oven,blast furnace hot blast furnace,copper smelting furnace,glass smelting kiln furnace,electric furnace roof.

2.Mainly used in the construction of regenerative chamber wall,chimney flue,combustion chamber, coking chamber, furnace roof etc. parts of the coke ovens.

3.Also used in hot blast stove/furnace of dome,furnace wall and checker brick.

4.Steel open hearth of regenerative chamber and sediment chamber,soaking furnace, glass melting furnace and ceramic firing kiln and kiln of the vault etc.
