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.
2). As ceramic parts of flexible pad and channel heaters at
operations of pre and postweld heat treatment; Welding process,
stress-relieving, pre-heating & post heating, other
resistance-heating environment
3). halogen lamps, high and low pressure uv lamps, mercury lamps,
uv lamp holders and heating tubes.
4). high-power electrical applicance and all kinds of insulation
device.
