Melting Furnace Natural Silica 2.35g Heat Resistant Fire Bricks
Definition:
Silica Material Brick belongs to acid refractory material, has good ability of resisting acid slag erosion, the softening temperature of load is as high as 1640 ~ 1670℃, the volume of long-term use is relatively stable under high temperature.
The Silica Material Brick is mainly an acid refractory material composed of scale quartz, calcite and a small amount of residual quartz and glass phase.
The silica content of Silica Material Brick is above 94%.True density 2.35g/cm3.It is resistant to acid slag. Higher high temperature strength. High refractoriness under load. In high temperature for a long time without deformation. Low thermal shock stability. Using natural silica as raw material, with appropriate amount of mineralization agent, to promote the conversion of quartz in the billet to scale quartz.
It 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) Silicon oxide is above 91%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C
Application:
Silica Material Brick 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.
It is also used for high temperature load bearing parts of hot blast furnace and acid open hearth furnace top.
