High Quantity Silica Insulation Refractory Brick for Glass Furnace
The Description:
Also known as silicon heat insulation brick. Lightweight refractory material with silica above 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are not much different from that of ordinary silicon bricks with the same composition. However, due to many pores, the compressive strength, slag resistance and corrosion resistance are not as good as ordinary silicon bricks, and the thermal shock resistance has been improved.
The use of fine 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%. A porous structure is formed by adding flammable substances to the ingredients or by gas generation method, and is prepared by firing. It can also be made into non-burning products. It is mainly used in various parts of the furnace that require heat insulation or weight reduction without direct contact with the melt, without the action of corrosive gases, and without sudden temperature changes. It is used at high temperature and cannot be in contact with alkaline refractory materials. Depending on the material, its maximum use temperature is 1200 ~ 1550ºC.
