Introduction of silica 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 heat-conductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.
Feature of silica brick :
1. Better durability. It can withstand continuous heat load within the temperature limits.
2. Low thermal conductivity. It has the incomparable insulation performance within the application range.
3. Light weight and high specific strength. Its specific strength is the highest among the rigid insulation materials.
4. Long service life. It will not produce the powder after long periods of operation as the ceramic fiber felt will do.
5. Better application adaptability. It can be Free Cutting by ordinary woodworking tools.
6. Safe and clean. It has not toxic materials such as asbestos sulfur and chlorine.
Not afraid of wetted. Its performance remain unchanged after being dried
