Fireproof Silica Refractory Bricks

Refractory Fire Resistant Silica Brick

 

Definition:

Refractory Fire Resistant 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.

 

Refractory Fire Resistant Silica Brick is slowly fired at 1350 ~ 1430℃ in reducing atmosphere. When heated to 1450℃, about 1.5~2.2% of the total volume expansion, the residual expansion will make the cut joints close, to ensure that the masonry has good air tightness and structural strength.

 

Advantage:

 

    (1) Refractoriness under load:

    The refractoriness under load of Refractory Material​​ is higher than that of clay brick and high aluminum brick, reaching 1640 ~ 1670℃, which belongs to advanced refractory materials. 

 

    (2) Thermal conductivity:

    Refractory Material​​ ​ has better thermal conductivity than clay brick and high aluminum brick

 

Application:

    

  Refractory Material​​ is mainly used for the partition of coking chamber and combustor of coke making furnace, regenerator chamber and cinder chamber of steelmaking open hearth furnace, soaking pit, refractory material of glass melting furnace and sintering furnace of ceramics and other kiln vault and other load-bearing parts.

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.
