Definition:
Insulating Silica Fireproof Brick is also known as silica insulation brick. Lightweight refractories with silica above 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are not much different from ordinary silicon bricks with the same composition.
However, due to the large number of pores, the compressive strength, slag resistance, and corrosion resistance are not as good as those of ordinary silicon bricks, but the thermal shock resistance has been improved.
Using finely divided silica as raw material, the critical particle size is usually not more than 1mm, and the particles less than 0.5mm are not less than 90%. Add flammable substances to the ingredients or use the gas generation method to form a porous structure, which is obtained by firing. Can also be made into non-burning products.
Insulating Silica Fireproof Brick is mainly used in various parts of the kiln that require heat insulation or reduce its own weight without direct contact with the melt, without the action of aggressive gases, or with sudden temperature changes. When used at high temperature, it must not be in contact with alkaline refractories. According to different materials, the maximum service temperature is 1200～1550℃.
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:
Insulating Silica Fireproof Brick are used in the Metallurgy, building materials, chemical industry, petroleum, machinery manufacturing, silicate, power and other industries.
It’s widely used for the linings and insulating layers of industry kilns, and the areas without strong erosion and souring action by molten materials at high temperature.
