Definition:
high density silica insulating fire bricks also called siliceous insulation brick. Lightweight refractory material with silicon dioxide above 91% and bulk density below 1.2g/cm3. The refractoriness and softening temperature under load are not much different from ordinary silica bricks with the same composition. However, due to the many pores, the compressive strength, slag resistance, and corrosion resistance are not as good as ordinary silica bricks, but the thermal shock resistance has been improved.
high density silica insulating fire bricks refer to heat-insulating refractory products made of silica as the main raw material and with an SiO2 content of not less than 91%. In addition to the thermal insulation properties of Insulating silica bricks, high density silica insulating fire bricks maintains the characteristics of silicon bricks to a large extent. The starting temperature of load softening is high, and the volume expands slightly during the heating process, which enhances the integrity of the kiln. The manufacture of siliceous high density silica insulating fire bricks uses finely pulverized silica as the raw material, adding part of the waste silica bricks or waste siliceous Insulating silica bricks powder, mineralizers and burnout additives. Add water to the mixer according to a certain proportion to mix into a mud, which is formed by mechanical or manual molding. After the brick is dried, the residual moisture is less than 0.5% before it can be loaded into the kiln. In order to prevent the violent volume expansion due to the polycrystalline transformation of SiO2, causing cracks in the product, a slower temperature rise and fall speed are required during firing.
Advantage:
1. Silicon oxide is above 90%.
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:
1. Glass furnace and Glass Kiln for glass industry
2. Hot blast furnace or stove
3. Iron Steel making furnaces
4. Ceramic tunnel kiln,Cement kiln
5. Other high temperature kiln furnace
