Definition:
Light Weight Silica Brick is made of quartz stone material, the content of SiO2 is above 93%. It has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C, RUL is beyond 1620°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 heat-conductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.
Advantage:
Lower impurity content
Excellent resistance in slag abrasion
No shrink in burn repeatedly
Super higher cold crush strength character
Good performance in high temp refractoriness under load
Higher temperate resistant with good refractoriness
Application:
Light Weight Silica Brick are used in the blast furnace blast area and communicate with the blast furnace exhaust. The light silicon bricks have a temperature range of 1000 ~ 1300 ℃. Can meet the whole cycle life of hot blast stove
Light Weight Silica Brick are also used in the partition walls of the carbonization and combustion chambers of coke ovens, the regenerators and slag chambers of open hearth furnaces, soaking furnaces, glass melting furnaces, refractory materials and ceramic firing kilns. There are also vaults and other load-bearing parts for kilns. It is also used for the high-temperature load-bearing part of hot blast stove and the top of acidic open hearth furnace.
