Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks
Standard sizing:This brick is special size for pipes of industry furance ,Special size and OEM Service also provide!
The size is precise, providing kinds of shapes according to customer's drawing
Definition:
Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks 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.
Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks is made of silicon as raw material with high temp firing ,which silicon oxide is above 93% ,used in hot blast furnace,coke oven,glass kiln,these brick have good volume stability at high temperature, high refractoriness under the load,small rate of shrinkage in working condition.
Advantage:
The Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks for coke oven has low alkali and low content of residual quartz.
The Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks has high strength and refractoriness under load.
The Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks also has strong ability in acid slag resistance.
This Blast Stove Used Silica Fire Resistant Refractory Brick Silica Refractory Bricks is used to the walls, hearth or other parts of the combustion chamber, and carbonization chamber
Application:
1). Gas cooker,Water heater,Gas oven, Gas boiler,Air-conditioning and so on.
